The fishing industry dominated by artisanal marine fishing helps Ghana to meet its fish and protein requirements. Also, it provides employment for most coastal dwellers that depend on fishing as their main economic enterprise. Nonetheless, the marine fishing industry is confronted with challenges that have contributed to a declining fish production in recent past decade. Bad fishing practices and the general limited knowledge on sustainable management of fisheries resources are the limiting factors that affect sustainable fish production and sustainable marine biodiversity management in Ghana. This paper discusses the challenges and strategies for attaining and maintaining sustainable marine fishing in Ghana as well as the state of marine fishing in Ghana. It concludes that an increase in the level of involvement of local fishers in the management of fisheries resources of the country could help local fishers to employ sustainable fisheries resources exploitation methods that could result in an improvement in the spatio-economic development and wellbeing of affected fishing communities in particular and Ghana in general. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pair%20trawling" title="pair trawling">pair trawling</a>, <a href="https://publications.waset.org/abstracts/search?q=sargassum" title=" sargassum"> sargassum</a>, <a href="https://publications.waset.org/abstracts/search?q=spatio-economic%20development" title=" spatio-economic development"> spatio-economic development</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20marine%20fishing" title=" sustainable marine fishing"> sustainable marine fishing</a> </p> <a href="https://publications.waset.org/abstracts/86329/challenges-of-sustainable-marine-fishing-in-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4824</span> Illegal, Unreported and Unregulated (IUU) Fishing in ASEAN Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen%20Chiat%20Lee">Wen Chiat Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20Kuperan%20Viswanathan"> K.

Understanding the reasons contributing to IUU fishing is crucial in reducing it. Economic, institutional and social factors are key drivers of IIU fishing. The economic factor is the main contributor to IUU fishing. The two possible ways to curb the IUU fishing is highlighted. One way is to reduce the revenue from IUU fishing and another way is to increase the cost of IUU fishing. There are three costs of IUU fishing that can be increased namely the operating, capital and risk costs. Approaches for reducing the economic rent or profit from IUU fishing are developed and directions for reducing IUU fishing are also suggested. Improved registration of fishing vessels, preventing entry of illegal fish products and most importantly, developing co-management of fisheries are the ways forward for reducing IUU fishing. All governments in ASEAN must work in tandem with the stakeholders involved such as fishers, fishermen agencies or associations to exchange information for reducing the transaction cost of IUU fishing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Illegal" title="Illegal">Illegal</a>, <a href="https://publications.waset.org/abstracts/search?q=unreported%20and%20unregulated%20%28IUU%29%20fishing" title=" unreported and unregulated (IUU) fishing"> unreported and unregulated (IUU) fishing</a>, <a href="https://publications.waset.org/abstracts/search?q=co-management" title=" co-management"> co-management</a>, <a href="https://publications.waset.org/abstracts/search?q=fisheries%20management" title=" fisheries management"> fisheries management</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20rent%20framework" title=" economic rent framework"> economic rent framework</a> </p> <a href="https://publications.waset.org/abstracts/53286/illegal-unreported-and-unregulated-iuu-fishing-in-asean-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53286.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">231</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4823</span> A Fishery Regulation Model: Bargaining over Fishing Pressure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duplan%20Yves%20Jamont%20Junior">Duplan Yves Jamont Junior</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Diamond-Mortensen-Pissarides model widely used in labor economics is tailored to fishery. By this way, a fishing function is defined to depict the fishing technology, and Bellman equations are established to describe the behaviors of fishermen and conservationists. On this basis, a negotiation takes place as a Nash-bargaining over the upper limit of the fishing pressure between both political representative groups of fishermen and conservationists. The existence and uniqueness conditions of the Nash-bargained fishing pressure are established. Given the biomass evolution equation, the dynamics of the model variables (fishing pressure, biomass, fish need) is studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation" title="conservation">conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=fishery" title=" fishery"> fishery</a>, <a href="https://publications.waset.org/abstracts/search?q=fishing" title=" fishing"> fishing</a>, <a href="https://publications.waset.org/abstracts/search?q=Nash%20bargaining" title=" Nash bargaining"> Nash bargaining</a> </p> <a href="https://publications.waset.org/abstracts/60301/a-fishery-regulation-model-bargaining-over-fishing-pressure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60301.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">260</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4822</span> Initiating Learning to Know among Fishers for Sustainable Fishery on Lake Victoria.

This study sought to initiate self-direction for lifelong learning through social constructivism among fishers; with the major goal of creating a community of fishers who continuously learn from each other for sustainable fishing. Government of Uganda has instituted several mechanisms like co-management with Beach Management Unit (BMU) System against illegal fishing. However, illegal fishing persists, there is reduced fish stocks with several outcry on how fishers are handled. Some studies have indicated that it’s the poor orientation of BMU leaders and fishers which are top down. This initial engagement of fishers was conducted through a meeting and use of stake holder’s analysis tool to discuss the relevance of the study; harnessing fishers’ knowledge for sustainable fisheries on Lake Victoria, its objectives, the key stake holders to enable them fish sustainably. It revealed initial attempt to learn from each other and learning to know among fishers, with some elements of self-direction. However, fishers attempt to learning and self-direction are affected by prior brutal enforcement experiences. This meeting led to fishers gain some sense of hope towards enforcement brutality. The key stakeholders highlighted include MAAIF, FAO, UNBS, NaFIRRI, LVFO, BMU, UFPEA, Fishers m employers, Fisheries Protection Unit, GIZ, and any Non-Government organization but declined the Association of Fisheries and Lake Users in Uganda. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self%20direction" title="self direction">self direction</a>, <a href="https://publications.waset.org/abstracts/search?q=lifelong%20learning" title=" lifelong learning"> lifelong learning</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20constructivism" title=" social constructivism"> social constructivism</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20fishing" title=" sustainable fishing"> sustainable fishing</a> </p> <a href="https://publications.waset.org/abstracts/164141/initiating-learning-to-know-among-fishers-for-sustainable-fishery-on-lake-victoria-a-case-of-kigungu-fishing-ground-wakiso-district" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164141.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4821</span> Catch Composition and Amount of Illegal and Unreported Fishing in Iranian Coastal Waters - Hormozgan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasemi%20Mehran">Yasemi Mehran</a>, <a href="https://publications.waset.org/abstracts/search?q=Parsa%20Mehran"> Parsa Mehran</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzingohar%20Mehrnaz"> Farzingohar Mehrnaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Illegal, unreported, and unregulated (IUU) ﬁshing has been identiﬁed as one of the most serious threats to the sustainability of the world’s ﬁsheries. In the present study, illegal and unreported fishing of different species in waters of Persian Gulf and Oman Sea (Hormozgan province) were evaluated. Among 47 species of 33 families identified in this study, with 39 species belong to teleosts, 4 species belong to elasmobranchs and 4 species belong to invertebrate. The total weight of illegal and unreported catch were 78525.22 tonnes. Maximum and minimum values were found for Dussumiera acuta (20640.74 tonnes) and Tenualosa ilisha (0.733 tonnes), respectively. The most commercial species group was scombridae, carangidae and clupeidae, respectively. Teleosts with 91.15%, elasmobranchs with 4.82 and invertebrates with 4.03% constituted total weight of illegal and unreported fishing.

The growing demand for prawns is straining the sustainability of the Banjar Regency fishery. To ensure the long-term sustainability and economic viability of the prawn fishing in this region, it is imperative to implement evidence-based management practices. This requires comprehensive data on the Catch per Unit Effort (CPUE), Maximum Sustainable Yield (MSY) and the current rate of prawn resource exploitation. it analyzed five years of prawn catch data (2019-2023) obtained from South Kalimantan Marine and Fisheries Services. Fishing gears (e.g. hook & line and cast net) were first standardized with Fishing Power Index, and then calculated effort and MSY. The intercept (a) and the slope (b) values of regression curve were used to estimate the catch-maximum sustainable yield (CMSY) and optimal fishing effort (Fopt) levels within the framework of the Surplus Production Model. The estimated rates of resource utilization were then compared to the criteria of The National Commission of Marine Fish Stock Assessment. The findings showed that the CPUE value peaked in 2019 at 33.48 kg/trip, while the lowest value observed in 2022 at 5.12 kg/trip. The CMSY value was estimated to be 17,396 kg/year, corresponding to the Fopt level of 1,636 trips/year. The highest utilization rate was 56.90% recorded in 2020, while the lowest rate was observed in 2021 at 46.16%. The annual utilization rates were classified as “medium”, suggesting that increasing fishing effort by 45% could potentially maximize prawn catches at an optimum level. These findings provide a baseline for sustainable fisheries management in the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=giant%20prawns" title="giant prawns">giant prawns</a>, <a href="https://publications.waset.org/abstracts/search?q=CPUE" title=" CPUE"> CPUE</a>, <a href="https://publications.waset.org/abstracts/search?q=fishing%20power%20index" title=" fishing power index"> fishing power index</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20potential" title=" sustainable potential"> sustainable potential</a>, <a href="https://publications.waset.org/abstracts/search?q=utilization%20rate" title=" utilization rate"> utilization rate</a> </p> <a href="https://publications.waset.org/abstracts/192545/maximizing-giant-prawn-resource-utilization-in-banjar-regency-indonesia-a-cpue-and-msy-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192545.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">16</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4817</span> Understanding Willingness to Engage in pro-Environmental Behaviour among Recreational Anglers in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kelvin%20Mwaba">Kelvin Mwaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicole%20Strickland"> Nicole Strickland</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Objectives: Overexploitation and illegal fishing have been identified as the primary cause of the global decline in the fish stock. While commercial companies and small-scale fishing sectors are strictly regulated in South Africa, recreational anglers are not. The underlying assumption seems to be that recreational anglers can self-regulate. The aim of the present study was to investigate the relationship that recreational anglers have with nature and how this relationship can predict unlawful fishing practices. Methods: Using a survey design, 99 self-identified recreational anglers were recruited through convenient sampling. The anglers were accessed from fishing tackle shops around False Bay in the Western Cape province of South Africa. Data was collected using a self-administered questionnaire that consisted of pro-environmental behavior survey and the Nature Relatedness Scale. Results: Data analyses indicated that significant differences with regard to nature relatedness on the basis of participants’ age and level of education. Older and more educated anglers scored higher on nature relatedness than younger and less educated anglers. Logistic regression analysis showed that nature relatedness was a significant predictor of pro-environmental behaviors (R²= 0.061). Discussion and Conclusion: The findings of the present study provide support regarding the importance of encouraging healthy and sustainable relationships between humans and nature. Combating harmful fishing practices can achieve through understanding and promoting human care for nature among anglers and others involved in fishing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pro-environmental" title="pro-environmental">pro-environmental</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior" title=" behavior"> behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=anglers" title=" anglers"> anglers</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/88789/understanding-willingness-to-engage-in-pro-environmental-behaviour-among-recreational-anglers-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88789.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4816</span> Shark Fishing in Iceland: Ocean Oral History</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalr%C3%BAn%20Kaldakv%C3%ADsl%20Eyger%C3%B0ard%C3%B3ttir">Dalrún Kaldakvísl Eygerðardóttir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shark fishing has been practiced for centuries in Iceland. The broad objective of this ongoing research is to study the history of shark fishing in Iceland from the high days of Icelandic shark fishing in the latter half of the 19th century to recent days. The main focus is on shark fishing in the 20th and 21st century. The research sheds light on how sharks have shaped the Icelandic society and how Icelandic society has shaped the lives of sharks, by providing historical context to the relationship between Icelanders and one of the top predators in the North Atlantic Ocean, the Greenland shark. It is important to explore this aspect of Icelandic history further, to enhance people´s understanding of the marine ecosystem from the context of the past and the current increasing concerns about the status of sharks worldwide. Next to nothing has been written about shark fishing in the 20th and 21st Iceland, which shows the importance of interviewing shark fishermen – most of whom are at an old age today. The main methodology used in the research is oral history. Oral history is a large and growing field of research within history, which is based on obtaining oral sources through interviews, analyzing them, and presenting them. The video-poster sheds light on how oral history provides useful historical information on shark fishing and shark conservation in Iceland. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20history" title="oral history">oral history</a>, <a href="https://publications.waset.org/abstracts/search?q=shark%20fishing%20in%20Iceland" title=" shark fishing in Iceland"> shark fishing in Iceland</a>, <a href="https://publications.waset.org/abstracts/search?q=19.%20and%2021.%20century" title=" 19. and 21. century"> 19. and 21. century</a>, <a href="https://publications.waset.org/abstracts/search?q=shark%20conservation" title=" shark conservation"> shark conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20environmental%20history" title=" marine environmental history"> marine environmental history</a> </p> <a href="https://publications.waset.org/abstracts/164109/shark-fishing-in-iceland-ocean-oral-history" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164109.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4815</span> Navigating Rough Seas: A Qualitative Exploration of National Sociotechnical Imaginaries of Myanmar’s Future Marine Fisheries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hannes%20Groeneweg">Hannes Groeneweg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Myanmar is considered one of the largest fishing nations in the world. The country’s rapid economic and political reform process since 2011 entails both challenges and opportunities for its marine fishing sector. The development pathway of the sector remains unclear. Which future will eventually materialize is shaped and determined by the various visions and actions of the stakeholders engaging in political debates and decision-making. These visions can be conceptualized through the Science and Technology Studies (STS) concept of sociotechnical imaginaries. The research of this article is guided by the question of which imaginaries are currently relevant, who is propagating these imaginaries, and how are these imaginaries produced and contested. Using qualitative documentary analysis of policy documents, reports, and media articles as well as in-depth interviews with key stakeholders, three archetypical national sociotechnical imaginaries of Myanmar’s future marine fisheries were identified: The industrial scale extractivism imaginary views marine fishing sector as a driver for national economic growth and focuses on the industrial and technological development of the production chain, increasing yield and exports. Sustainable fishing management encompasses the vulnerability of marine ecosystems and views increasing efficient sustainability governance, planning, and management into existing fishing practices. In the traditional sufficiency fishing imaginary, small-scale fishing practices are viewed as an important livelihood practice for millions of coastal dwellers. The need to conserve them through strengthening the self-reliance, autonomy, and resilience of these communities is stressed. In national debates, the first two imaginaries are currently dominant. The imaginaries, as well as their contestations, are also linked to other critical political issues. The paper suggests that participatory decision-making processes are needed to create an inclusive imaginary of the future marine fishing sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=science%20and%20technology%20studies" title="science and technology studies">science and technology studies</a>, <a href="https://publications.waset.org/abstracts/search?q=sociotechnical%20imaginaries" title=" sociotechnical imaginaries"> sociotechnical imaginaries</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20fishing" title=" marine fishing"> marine fishing</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20coproduction" title=" knowledge coproduction"> knowledge coproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=Myanmar" title=" Myanmar"> Myanmar</a> </p> <a href="https://publications.waset.org/abstracts/131477/navigating-rough-seas-a-qualitative-exploration-of-national-sociotechnical-imaginaries-of-myanmars-future-marine-fisheries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131477.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4814</span> Status of Artisanal Fishery in Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esmail%20Shakman">Esmail Shakman</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Etyab"> Khaled Etyab</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibraheim%20Taboni"> Ibraheim Taboni</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Et-wail"> Mohamed Et-wail</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdallah%20Ben%20Abdallah"> Abdallah Ben Abdallah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was carried out along the Libyan coast during the period from 1st February to 31st March 2013.

The study found that more than 91% of the landing sites were permanent and around 8% were seasonal. The type of landing sites were mostly harbors (42.86%), 31.75% protected bays and 25.4% are open beach. However, seven types of fishing boats were observed; flouka type was the largest percentage (70.06%), then 18.14% for mator, 3.28% for lampara, 0.41% for Tarrad, Gayag (0.16%), 5.97 for Daghesa, and 1.98% for batah. Moreover, the majority of them were concentrated in the western region of the country. The most common used fishing gearsare the trammel nets about 80%, which are used by flouka, mator, Tarrad, and batah. The using of trammel nets rely on the fishing season, fishes size and the target fish species.

However, it can be catched by reef traps in some water sources. Freshwater shrimps are constantly catching for commercial reasons because of a favorite bait for angling. There are more or less damage catching fishing vehicles to the habitat. This study was carried out in the Kırkgöz spring, Antalya and examined the effect of reef traps on the Kırkgöz spring habitat. Reef traps used 18.5x23.5x25 cm perforated bricks are arranged next to each other, blocks of random dimensions are prepared in 5x10, 18x24, 7x8 meter dimensions. These blocks are constructed with two layers of bricks that are covered with various materials such as carpets and blankets. Then, freshwater shrimps enter the holes of bricks. The bricks are closed off from both sides and discharged into a container when it is desired to be caught. The reef traps built on the plants which staying on the plant for a long time have been damaging the vegetation under the reef traps. Fishermen are setting new traps on the plants to increase the fishing efficiency since the freshwater shrimps are among the water plants. As a result, this application disrupts the aquatic organisms in their habitats. It is important to use fishing gears which will cause less damage and conserve stocks for sustainable fishing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reef%20trap" title="reef trap">reef trap</a>, <a href="https://publications.waset.org/abstracts/search?q=Antalya" title=" Antalya"> Antalya</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a> </p> <a href="https://publications.waset.org/abstracts/83607/the-impact-on-habitat-of-reef-traps-used-in-the-freshwater-shrimp-palaemonetes-antennarius-h-milne-erwards-1837-catch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83607.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4812</span> Politicization of India Sri Lanka Fishing Dispute</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Faslan">Mohamed Faslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research examines the impact of the politicization of the fishing dispute on India-Sri Lanka relations, particularly the influence of internal and party politics. The maritime border is clearly demarcated between India and Sri Lanka. India and Sri Lanka signed bilateral agreements on maritime boundaries in 1974 and 1976 respectively. They signed the United Nations Law of the Sea- III as well. Despite this, fishing disputes persist between the two nations. Tamil Nadu politics is closely linked with Sri Lankan Tamil issues and Tamil Nadu has been playing a significant role in Indo-Lanka relations. This is due to the fact that many Indian trawlers involved in fishing activities in Sri Lankan waters are from Tamil Nadu. The Government of Tamil Nadu is also very concerned about the issue of fishing in Sri Lankan waters. During the ethnic war, Sri Lankan fishermen were restricted on fishing activities in the Northern sea by the Sri Lankan Government and Liberation Tigers of Tamil Elam (LTTE). This created a vacuum in the Northern sea of Sri Lanka, and Indian trawlers filled the vacuum with the support of the LTTE. After the end of the war, Northern fishermen of Sri Lanka recommenced their fishing activities and realized that the Tamil Nadu trawlers had scooped their fishing resources. The Northern fishermen started to protest the invasion of Indian trawlers and pushed the Sri Lankan Government to stop the Indian trawlers. When Sri Lanka arrested Indian fishermen and confiscated their fishing boats, the Tamil Nadu Government used this as an opportunity to accuse Sri Lanka as having a Sinhalese government, to express feelings of hatred towards Sri Lanka due to the ethnic war against Tamils and tried to increase the voting bank by selling Tamil feelings. Thus, this research finds that Tamil Nadu does not associate this fishing dispute with Tamils in Sri Lanka but with the Sinhalese despite the status quo. This research has covered the Northern fishermen and stakeholders of Sri Lanka and could not do any field research in India due to visa restrictions. However, the researcher tries to balance the gap by referring to secondary sources and a few interviews with Indian scholars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indo%20Lanka%20relations" title="Indo Lanka relations">Indo Lanka relations</a>, <a href="https://publications.waset.org/abstracts/search?q=fishing%20dispute" title=" fishing dispute"> fishing dispute</a>, <a href="https://publications.waset.org/abstracts/search?q=maritime%20border" title=" maritime border"> maritime border</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamil%20Nadu%20%26%20Sri%20Lankan%20waters" title=" Tamil Nadu & Sri Lankan waters"> Tamil Nadu & Sri Lankan waters</a> </p> <a href="https://publications.waset.org/abstracts/13595/politicization-of-india-sri-lanka-fishing-dispute" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13595.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4811</span> Bioeconomic Modelling for Barramundi (Lates calcarifer) in Queensland: Implications for Recreational Fishing Following Recent Gill Netting Closures </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabiha%20S.%20Marine">Sabiha S.

This management change is likely to improve the potential for more desirable stock structures through natural recruitment. Barramundi (Lates calcarifer) is one of the popular target fish for recreational and commercial fishers in Northern Australia. This investigation examines the effects of reduced commercial fishing from both biological and economic perspectives, particularly on the local Barramundi population of the Fitzroy River in Rockhampton, the largest river catchment flowing to the eastern coast of Australia. Data on different parameters of biological and economic aspects have been collated from secondary sources for analysis through a system simulation approach to identify the effectiveness of the commercial netting closures on recreational fishing effort, especially for the Barramundi population. The results have the potential to explain certain consequences of the netting closures in Queensland, which could serve to inform future fisheries management decisions. The study output as a whole will help in the better management of fisheries resources by evaluating recreational fishing opportunities in Queensland, where the potential for increases in recreation is high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barramundi" title="Barramundi">Barramundi</a>, <a href="https://publications.waset.org/abstracts/search?q=bioeconomic%20model" title=" bioeconomic model"> bioeconomic model</a>, <a href="https://publications.waset.org/abstracts/search?q=fishery%20management" title=" fishery management"> fishery management</a>, <a href="https://publications.waset.org/abstracts/search?q=recreational%20fishing" title=" recreational fishing"> recreational fishing</a> </p> <a href="https://publications.waset.org/abstracts/88961/bioeconomic-modelling-for-barramundi-lates-calcarifer-in-queensland-implications-for-recreational-fishing-following-recent-gill-netting-closures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88961.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4810</span> Production Value, Constraints, and Opportunities in East African Freshwater Fisheries: Systematic Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alamrew%20Eyayu">Alamrew Eyayu</a>, <a href="https://publications.waset.org/abstracts/search?q=Abebe%20Getahun"> Abebe Getahun</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Last%20Keyombe"> James Last Keyombe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Demand for fish continued to grow worldwide while production from capture fisheries has decreased. In the Eastern African Region (EAR), the open-access nature of capture fisheries has resulted in illegal fishing. Within communities engaged in fishing, small-scale fisheries support food security strategies and sustain livelihoods. Despite the role of fisheries in EAR, inland fisheries are vulnerable to loss, and management solutions authorized for inland fisheries are inadequate. This review investigates production potential, challenges, opportunities, and management of inland fisheries in the EAR. It is therefore expected that in aquaculture promising areas, the EAR will turn to depend more on aquaculture to meet the extended needs and supply gaps created as a result of capture fisheries shortfalls. However, aquaculture is still in its infant stage in the region, and there exists no adequate aquaculture policy framework and funds in some EAR (e.g., Ethiopia, Somalia). Stakeholders at all levels should entertain the importance of fishery-based activities for food security in EAR. As a result, easily implemented and community-oriented fisheries legislative documents need to be prepared for advancing sustainable fisheries management. Legislative documents might consider techniques of continual catch statistics (consider small water bodies as much as possible) of inland fisheries and enforcing existing laws to manage illegal fishing activities to accustom sustainable development of inland capture fisheries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquaculture" title="aquaculture">aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=capture%20fisheries" title=" capture fisheries"> capture fisheries</a>, <a href="https://publications.waset.org/abstracts/search?q=East%20Africa" title=" East Africa"> East Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=fisheries%20management" title=" fisheries management"> fisheries management</a> </p> <a href="https://publications.waset.org/abstracts/190374/production-value-constraints-and-opportunities-in-east-african-freshwater-fisheries-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">25</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4809</span> Socio-economic Baselining of Selected Icrmp Sites in Southwestern Cebu, Central Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachel%20Luz%20P.%20Vivas-rica">Rachel Luz P.

Four hundred sixteen (416) respondents from five barangays with Marine Protected Areas (MPAs) and four barangays without marine sanctuaries were considered in the study. Results showed similarity of socio-economic characteristics in terms of average age, majority were middle aged, and married. Households were male dominated, obtained low education for both MPA and Non-MPA areas. In terms of occupation, majority in both areas engaged in fulltime fishing however part time jobs as carpenter, construction worker, driver or farmer as another income source. Most of the households were nuclear families with average family size of five for both MPA and Non-MPA. Fishing experience ranged from less than 1 year to more than 50 years. Fishing grounds were within the 15 kilometer radius of each considered site. Even if the respondents were totally dependent on fishing as a major source of income, still their income is way below the poverty threshold both in the MPA and Non-MPA areas. This is further explained by the marginality of their fishing implements wherein majority uses gill nets, hook & line, spear and paddle boat in fishing. Their volume of catch from an average of 6 hours fishing expedition ranges from half a kilo to a maximum of 4 kilos. Majority are not members of fishing groups or organizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integrated%20coastal%20resource%20management%20program" title="integrated coastal resource management program">integrated coastal resource management program</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20protected%20areas" title=" marine protected areas"> marine protected areas</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-economic" title=" socio-economic"> socio-economic</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty%20threshold" title=" poverty threshold"> poverty threshold</a> </p> <a href="https://publications.waset.org/abstracts/39144/socio-economic-baselining-of-selected-icrmp-sites-in-southwestern-cebu-central-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39144.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">518</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4808</span> Modification Of Rubber Swab Tool With Brush To Reduce Rubber Swab Fraction Fishing Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20R.%20Hidayat">T.

During the swab activity, problems occur frequent problems occur with the rubber swab. The rubber swab often breaks and becomes a fish inside the well. This rubber swab fishing activity caused the rig operation takes longer, the swab result data becomes too late and create potential losses of well operation for the company. The average time needed for fishing the fractions of rubber swab plus swab work is 42 hours. Innovation made for such problems is to modify the rubber swab tool. The rubber swab tool is modified by provided a series of brushes at the end part of the tool with a thread of connection in order to improve work safety, so when the rubber swab breaks, the broken swab will be lifted by the brush underneath; therefore, it reduces the loss time for rubber swab fishing. This tool has been applied, it and is proven that with this rubber swab tool modification, the rig operation becomes more efficient because it does not carry out the rubber swab fishing activity. The fish fractions of the rubber swab are lifted up to the surface. Therefore, it saves the fuel cost, and well production potentials are obtained. The average time to do swab work after the application of this modified tool is 8 hours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rubber%20swab" title="rubber swab">rubber swab</a>, <a href="https://publications.waset.org/abstracts/search?q=modifikasi%20swab" title=" modifikasi swab"> modifikasi swab</a>, <a href="https://publications.waset.org/abstracts/search?q=brush" title=" brush"> brush</a>, <a href="https://publications.waset.org/abstracts/search?q=fishing%20rubber%20swab" title=" fishing rubber swab"> fishing rubber swab</a>, <a href="https://publications.waset.org/abstracts/search?q=saving%20cost" title=" saving cost"> saving cost</a> </p> <a href="https://publications.waset.org/abstracts/142856/modification-of-rubber-swab-tool-with-brush-to-reduce-rubber-swab-fraction-fishing-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142856.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4807</span> Studying the Value-Added Chain for the Fish Distribution Process at Quang Binh Fishing Port in Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Van%20Chung%20Nguyen">Van Chung Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to study the current status of the value chain for fish distribution at Quang Binh Fishing Port with 360 research samples in which the research subjects are fishermen, traders, retailers, and businesses. The research uses the approach of applying the value chain theoretical framework of Kaplinsky and Morris to quantify and describe market channels and actors participating in the value chain and analyze the value-added process of these companies according to market channels. The analysis results show that fishermen directly catch fish with high economic efficiency, but processing enterprises and, especially retailers, are the agents to obtain higher added value. Processing enterprises play a role that is not really clear due to outdated processing technology; in contrast, retailers have the highest added value. This shows that the added value of the fish supply chain at Quang Binh fishing port is still limited, leading to low output quality. Therefore, the selling price of fish to the market is still high compared to the abundant fish resources, leading to low consumption and limiting exports due to the quality of processing enterprises. This reduces demand and fishing capacity, and productivity is lower than potential. To improve the fish value chain at fishing ports, it is necessary to focus on improving product quality, strengthening linkages between actors, building brands and product consumption markets at the same time, improving the capacity of export processing enterprises. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Quang%20Binh%20fishing%20port" title="Quang Binh fishing port">Quang Binh fishing port</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20chain" title=" value chain"> value chain</a>, <a href="https://publications.waset.org/abstracts/search?q=market" title=" market"> market</a>, <a href="https://publications.waset.org/abstracts/search?q=distributions%20channel" title=" distributions channel"> distributions channel</a> </p> <a href="https://publications.waset.org/abstracts/173556/studying-the-value-added-chain-for-the-fish-distribution-process-at-quang-binh-fishing-port-in-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173556.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4806</span> Mobulid Ray Post-Release Mortality to Assess the Feasibility of Live-Release Management Measures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sila%20K.%20Sari">Sila K.

Among elasmobranchs, mobulid rays are faced with high extinction risk due to intrinsic vulnerability to fishing and their conservation has been recognized as a strong priority both in Indonesia and worldwide. Despite their common vulnerabilities to fishing pressure due to slow growth, late maturation and low fecundity, only manta rays, but not devil rays, are protected in Indonesian waters. However, both manta and devil rays are captured in non-selective fisheries, in particular drift gillnets, since their habitat overlaps with fishing grounds for primary target species (e.g. marlin, swordfish and bullet tuna off the coast of Muncar). For this reason, mobulid populations are being heavily impacted, and while national-level protections are crucial to help conservation, they may not suffice alone to insure populations sustainability. In order to assess the potential of applying live-release management measures to conserve mobulids captured as bycatch in drift gillnets, we deployed pop-up survival archival transmitters to assess post-release mortality in Indonesian mobulid rays. We also assessed which fishing practices, in particular, soak duration, affected post-release mortality in order to draw relevant conclusions for management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mobulid" title="Mobulid">Mobulid</a>, <a href="https://publications.waset.org/abstracts/search?q=Devil%20ray" title=" Devil ray"> Devil ray</a>, <a href="https://publications.waset.org/abstracts/search?q=Manta%20ray" title=" Manta ray"> Manta ray</a>, <a href="https://publications.waset.org/abstracts/search?q=Bycatch" title=" Bycatch"> Bycatch</a> </p> <a href="https://publications.waset.org/abstracts/120119/mobulid-ray-post-release-mortality-to-assess-the-feasibility-of-live-release-management-measures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120119.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4805</span> Marine Fishing and Climate Change: A China’s Perspective on Fisheries Economic Development and Greenhouse Gas Emissions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yidan%20Xu">Yidan Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Pim%20Martens"> Pim Martens</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Krafft"> Thomas Krafft</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Marine fishing, an energy-intensive activity, directly emits greenhouse gases through fuel combustion, making it a significant contributor to oceanic greenhouse gas (GHG) emissions and worsening climate change. China is the world’s second-largest economy and the top emitter of GHG emissions, and it carries a significant energy conservation and emission reduction burden. However, the increasing GHG emissions from marine fishing is an easily overlooked but essential issue in China. This study offers a diverse perspective by integrating the concepts of total carbon emissions, carbon intensity, and per capita carbon emissions as indicators into calculation and discussion. To better understand the GHG emissions-Gross marine fishery product (GFP) relationship and influencing factors in Chinese marine fishing, the relationship between GHG emissions and economic development in marine fishing, a comprehensive framework is developed by combining the environmental Kuznets curve, the Tapio elasticity index, and the decomposition model. Results indicated that (1) The GHG emissions increased from 16.479 to 18.601 million tons in 2001-2020, in which trawlers and gillnetter are the main source in fishing operation. (2) Total carbon emissions (TC) and CI presented the same decline as GHG emissions, while per capita carbon emissions (PC) displayed an uptrend. (32) GHG emissions and gross marine fishery product (GFP) presented an inverted U-shaped relationship in China; the turning point came in the 13th Five-year Plan period (2016-2020). (43) Most provinces strongly decoupled GFP and CI. Still, PC and TC need more effort to decouple. (54) GHG emissions promoted by an industry structure driven, though carbon intensity and industry scale aid in GHG emissions reduced. (5) Compare with TC and PC, CI has been relatively affected by COVID-19 in 2020. The rise in fish and seafood prices during COVID-19 has boosted the GFP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marine%20fishing%20economy" title="marine fishing economy">marine fishing economy</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse%20gas%20emission" title=" greenhouse gas emission"> greenhouse gas emission</a>, <a href="https://publications.waset.org/abstracts/search?q=fishery%20management" title=" fishery management"> fishery management</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20development" title=" green development"> green development</a> </p> <a href="https://publications.waset.org/abstracts/172786/marine-fishing-and-climate-change-a-chinas-perspective-on-fisheries-economic-development-and-greenhouse-gas-emissions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172786.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4804</span> Assessment of Women Involvement in Fishing Activities: A Case Study of Epe and Ibeju Lekki LGA, Lagos </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temitope%20Adewale">Temitope Adewale</a>, <a href="https://publications.waset.org/abstracts/search?q=Oladapo%20Raji"> Oladapo Raji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study was designed to investigate the assessment of women's involvement in fishing.

Pi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hampal (Hampala macrolepidota) is one of Citarum river indigenous fishes that still find in Jatiluhur dam. IUCN at 2013 said that hampal listed on redlist species category, this species was rare in Jatiluhur dam. This species more and more decreasing because change of habitats characteristic such as water quality and fishing effort. This study aims to determine and identify the influence of fishing effort and the quality of water on the productivity of fish resources hampal (Hampala macrolepidota) in Jatiluhur. The study was conducted from October to November 2013. Zones of research include lacustrine zone, transition and Riverin. Hampal fish productivity value computed by Hampal’s CPUE values. The results showed that fish MSY hampal obtained from surplus production model of Schaefer is equal to 0.2045 tons / quarterly. In the years 2011-2012 have occurred over fishing in 2013 while still under fishing. Total catches have exceeded the MSY during the year 2011 and the third quarterly of 2012 tons of fish that exceed 0.2045 hampal. The rate of utilization of fish resources hampal is equal to 80% of MSY or equal to the allowable catch (Total Allowable Catch) for fish in Jatiluhur hampal based Schaefer surplus production theory. Fishing effort, water quality parameters such as DO, turbidity and negatively correlated sulfide as H2S, while the temperature and pH positively correlated to productivity or unit catches fish hampal efforts in quarterly time series in the period 2011-2013. Shows that the higher fishing effort, DO, turbidity and sulfide in H2S and diminishing the temperature and pH of the productivity decreases. Variables that affect the productivity of fishing hampal only H2S only factor beta coefficient -0.834 which indicates a negative effect. It can be caused by H2S levels are toxic and have already exceeded the quality standard, while for other water quality parameters are still below the maximum standards allowed in the waters. Result of the study can be a reference of fishing regulation for hampal conservation in Jatiluhur dam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effort" title="effort">effort</a>, <a href="https://publications.waset.org/abstracts/search?q=hampal" title=" hampal"> hampal</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/23337/effects-of-effort-and-water-quality-on-productivity-cpue-of-hampal-hampala-macrolepidota-resources-in-jatiluhur-dam-west-java" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23337.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4802</span> Feasibility on Introducing an Alternative Solar Powered Propelling Mechanism for Multiday Fishing Boats in Sri Lanka</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oshada%20Gamage">Oshada Gamage</a>, <a href="https://publications.waset.org/abstracts/search?q=Chamal%20Wimalasooriya"> Chamal Wimalasooriya</a>, <a href="https://publications.waset.org/abstracts/search?q=Chrismal%20Boteju"> Chrismal Boteju</a>, <a href="https://publications.waset.org/abstracts/search?q=W.%20K.%20Wimalsiri"> W.

Since solar energy is readily available on the sea throughout the year, this free energy could be utilized to power multi-day fishing vessels. Multi-day boats have a large deck area where solar panels can be mounted above without much effort. This project involves studying the amount of power that can be generated using onboard solar panels and implementing an independent propelling system to run the boat. A chain drive system was designed to propel the boat, when the batteries are fully charged, from an electric motor using the same propeller. A 60 feet multi-day fishing boat built by a local boat manufacturer was chosen for the study. The service speed of the boat was around 6 knots with the electric motor, and the duration of cruising is 1 hour per day with around 11 hours of charging. 350-watt Mono-crystalline PV module, 75 kW HVH type motor, and 10 kWh lithium-ion battery packs were chosen for the study. From the calculations, it was obtained that the boat has 30 PV modules (10.5 kW), 5 batteries (47 kWh), The boat dimensions are 20 meter length of water line, 5.51 meter of beam, 1.8 meter of draught, and 77 ton of total displacement with the PV system net present value of USD 12445 for 20 years of operation and a payback period of around 8.2 years. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiday%20fishing%20boats" title="multiday fishing boats">multiday fishing boats</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20cells" title=" photovoltaic cells"> photovoltaic cells</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20powered%20boat" title=" solar powered boat"> solar powered boat</a> </p> <a href="https://publications.waset.org/abstracts/131035/feasibility-on-introducing-an-alternative-solar-powered-propelling-mechanism-for-multiday-fishing-boats-in-sri-lanka" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131035.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4801</span> Efficient Utilization of Unmanned Aerial Vehicle (UAV) for Fishing through Surveillance for Fishermen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Ahilan">T.

The results showed that cases of Illegal Fishing by Foreign Nationals (WNA) in the Indonesian Exclusive Economic Zone (EEZ) were examined, tried, and decided in accordance with the fisheries law, criminal sanctions were not in accordance with and contrary to Indonesian positive law, both criminal law and fisheries law, but followed and were in line with UNCLOS Year 1982. Legal status and responsibility are only imposed on the master as the leader on board the ship as the representative of the ship owner/company. Meanwhile, the application of Indonesia's positive law to Unclos in 1982 was only in the form of fines and confiscation of evidence as an effort to seek compensation for illegal fishing activities in the waters of the Indonesian Exclusive Zone (EEZ). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EEZ" title="EEZ">EEZ</a>, <a href="https://publications.waset.org/abstracts/search?q=illegal%20fishing" title=" illegal fishing"> illegal fishing</a>, <a href="https://publications.waset.org/abstracts/search?q=WNA" title=" WNA"> WNA</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20law" title=" positive law"> positive law</a>, <a href="https://publications.waset.org/abstracts/search?q=Unclos%201982" title=" Unclos 1982"> Unclos 1982</a> </p> <a href="https://publications.waset.org/abstracts/184501/implementation-of-unclos-1982-on-capture-fisheries-in-the-case-of-illegal-fishing-in-the-waters-of-indonesias-exclusive-economic-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184501.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4799</span> Simulation of Climatic Change Effects on the Potential Fishing Zones of Dorado Fish (Coryphaena hippurus L.) in the Colombian Pacific under Scenarios RCP Using CMIP5 Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Mart%C3%ADnez-Arias">Adriana Martínez-Arias</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Josephraj%20Selvaraj"> John Josephraj Selvaraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Octavio%20Gonz%C3%A1lez-Salcedo"> Luis Octavio González-Salcedo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the Colombian Pacific, Dorado fish (Coryphaena hippurus L.) fisheries is of great commercial interest. However, its habitat and fisheries may be affected by climatic change especially by the actual increase in sea surface temperature. Hence, it is of interest to study the dynamics of these species fishing zones. In this study, we developed Artificial Neural Networks (ANN) models to predict Catch per Unit Effort (CPUE) as an indicator of species abundance. The model was based on four oceanographic variables (Chlorophyll a, Sea Surface Temperature, Sea Level Anomaly and Bathymetry) derived from satellite data. CPUE datasets for model training and cross-validation were obtained from logbooks of commercial fishing vessel. Sea surface Temperature for Colombian Pacific were projected under Representative Concentration Pathway (RCP) scenarios 4.5 and 8.5 using Coupled Model Intercomparison Project Phase 5 (CMIP5) and CPUE maps were created. Our results indicated that an increase in sea surface temperature reduces the potential fishing zones of this species in the Colombian Pacific. We conclude that ANN is a reliable tool for simulation of climate change effects on the potential fishing zones. This research opens a future agenda for other species that have been affected by climate change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climatic%20change" title="climatic change">climatic change</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title=" artificial neural networks"> artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=dorado%20fish" title=" dorado fish"> dorado fish</a>, <a href="https://publications.waset.org/abstracts/search?q=CPUE" title=" CPUE"> CPUE</a> </p> <a href="https://publications.waset.org/abstracts/72223/simulation-of-climatic-change-effects-on-the-potential-fishing-zones-of-dorado-fish-coryphaena-hippurus-l-in-the-colombian-pacific-under-scenarios-rcp-using-cmip5-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4798</span> Adaptation to Climate Change: An Anthropological Study on Changing Livelihood Strategies in South-West Coastal Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashik%20Sarder">Ashik Sarder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bangladesh is a disaster-prone and one of the most vulnerable countries to climate change. The country has a long coastal area which is frequently being affected by several types of natural disasters due to climate change. The disasters have impacts on the life and livelihood of different natural resources depending on communities living in the coastal areas. The Malo is a Hindu religious traditional fishing community living at Sarafpur Union of Dumuria Upazila of Khulna district of south-west coastal Bangladesh. Fishing is the only means of their livelihood and the community has been engaged in fishing practices inherently in rivers, estuaries, and sea for more than 300 years. and they are totally dependent on this traditional occupation. But, in recent year’s climate change has negative impacts on their only livelihood option. The study aims to examine the impacts of climate change on the livelihood of Malo fishing community in south-west coastal Bangladesh, identify the adaptation strategies undertaken and practiced by Malo fishing community to cope with climate change and sustain their livelihood and explore the changing adaptation strategies undertaken by Malo fishing community and others. The study has been conducted from both qualitative and quantitative perspectives. Data has been collected from both primary and secondary sources. The primary data has been collected in the participatory observation approach following both qualitative and quantitative method. The primary source of data includes village census, face-to-face interview and in-depth case studies using structured questionnaire. The secondary source of the literature includes different national and international documents, policy papers, books and articles; related websites and peer-viewed documents on climate change, vulnerability, adaptation, livelihood, and fisheries. The study has identified different practices of adaption to climate change by Malo fishing community and others in the selected area. Three types of adaption practices have been identified. Firstly, the indigenous adaptation practices by Malo fishing community to cope with climate change have been identified. These identified adaptation practices by Malo fishing community include; ensuring drinking water and sanitation facilities, planting trees to tackle impacts of cyclone, excavating dumps to preserve the valuable assets, growing vegetables and rearing domestic livestock to earn surplus money, taking loans for ensuring continuation of present livelihood and migrating to near city or towns for better livelihood options. Secondly, adaptation initiatives undertaken by the government have provided limited facility to this vulnerable fishing community and made them benefited. And thirdly, some adaptation initiatives commenced by few non-government and community-based organizations have also made the Malo fishing community as beneficiaries. The study has suggested recommendations for Malo fishing community to overcome the challenges and impacts of climate change for retaining their traditional fishing livelihood. The accumulated recommendations would be very useful for the researchers, academicians, policy-makers of Government and non-government organizations to conduct more researches and take initiatives for Malo fishing community to make them more capable to sustain their fishing livelihood. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=livelihood" title=" livelihood"> livelihood</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptation" title=" adaptation"> adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropology" title=" anthropology"> anthropology</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title=" vulnerability"> vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/98172/adaptation-to-climate-change-an-anthropological-study-on-changing-livelihood-strategies-in-south-west-coastal-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98172.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">117</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4797</span> A Study on Aquatic Bycatch Mortality Estimation Due to Prawn Seed Collection and Alteration of Collection Method through Sustainable Practices in Selected Areas of Sundarban Biosphere Reserve (SBR), India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samrat%20Paul">Samrat Paul</a>, <a href="https://publications.waset.org/abstracts/search?q=Satyajit%20Pahari"> Satyajit Pahari</a>, <a href="https://publications.waset.org/abstracts/search?q=Krishnendu%20Basak"> Krishnendu Basak</a>, <a href="https://publications.waset.org/abstracts/search?q=Amitava%20Roy"> Amitava Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fishing is one of the pivotal livelihood activities, especially in developing countries. Today it is considered an important occupation for human society from the era of human settlement began. In simple terms, non-target catches of any species during fishing can be considered as ‘bycatch,’ and fishing bycatch is neither a new fishery management issue nor a new problem. Sundarban is one of the world’s largest mangrove land expanding up to 10,200 sq. km in India and Bangladesh. This largest mangrove biome resource is used by the local inhabitants commercially to run their livelihood, especially by forest fringe villagers (FFVs). In Sundarban, over-fishing, especially post larvae collection of wild Penaeus monodon, is one of the major concerns, as during the collection of P. monodon, different aquatic species are destroyed as a result of bycatch mortality which changes in productivity and may negatively impact entire biodiversity, of the ecosystem. Wild prawn seed collection gear like a small mesh sized net poses a serious threat to aquatic stocks, where the collection isn’t only limited to prawn seed larvae. As prawn seed collection processes are inexpensive, require less monetary investment, and are lucrative; people are easily engaged here as their source of income. Wildlife Trust of India’s (WTI) intervention in selected forest fringe villages of Sundarban Tiger Reserve (STR) was to estimate and reduce the mortality of aquatic bycatches by involving local communities in newly developed release method and their time engagement in prawn seed collection (PSC) by involving them in Alternate Income Generation (AIG). The study was conducted for their taxonomic identification during the period of March to October 2019. Collected samples were preserved in 70% ethyl alcohol for identification, and all the preserved bycatch samples were identified morphologically by the expertise of the Zoological Survey of India (ZSI), Kolkata. Around 74 different aquatic species, where 11 different species are molluscs, 41 fish species, out of which 31 species were identified, and 22 species of crustacean collected, out of which 18 species were identified. Around 13 different species belong to a different order, and families were unable to identify them morphologically as they were collected in the juvenile stage. The study reveals that for collecting one single prawn seed, eight individual life of associated faunas are being lost. Zero bycatch mortality is not practical; rather, collectors should focus on bycatch reduction by avoiding capturing, allowing escaping, and mortality reduction, and must make changes in their fishing method by increasing net mesh size, which will avoid non-target captures. But as the prawns are small in size (generally 1-1.5 inches in length), thus increase net size making economically less or no profit for collectors if they do so. In this case, returning bycatches is considered one of the best ways to a reduction in bycatch mortality which is a more sustainable practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bycatch%20mortality" title="bycatch mortality">bycatch mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=mangrove%20biome%20resource" title=" mangrove biome resource"> mangrove biome resource</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20practice" title=" sustainable practice"> sustainable practice</a>, <a href="https://publications.waset.org/abstracts/search?q=Alternate%20Income%20Generation%20%28AIG%29" title=" Alternate Income Generation (AIG)"> Alternate Income Generation (AIG)</a> </p> <a href="https://publications.waset.org/abstracts/164722/a-study-on-aquatic-bycatch-mortality-estimation-due-to-prawn-seed-collection-and-alteration-of-collection-method-through-sustainable-practices-in-selected-areas-of-sundarban-biosphere-reserve-sbr-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164722.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4796</span> Assessment of Household Livelihood Diversification and Fisheries Conservation Strategies among Fishermen in Coastal Areas of Ogun State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adeosun">Adeosun</a>, <a href="https://publications.waset.org/abstracts/search?q=Festus%20Idowu%3B%20Omoniyi"> Festus Idowu; Omoniyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Tunde"> Isaac Tunde</a>, <a href="https://publications.waset.org/abstracts/search?q=Adeosun">Adeosun</a>, <a href="https://publications.waset.org/abstracts/search?q=Olamide%20Modinat"> Olamide Modinat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study assessed the association between household livelihood diversification and fisheries conservation policies among fishermen in coastal areas of Ogun State, Nigeria by adopting a multistage sampling procedure. The sample size was 90 fishermen from six randomly selected fishing communities (Abureji, Agbalegiyo, Ilamo, Imosan, Iseku and Wharf) along the coastline in Ogun State, Nigeria. Data were collected using pre-validated interview schedule and subjected to descriptive and inferential analytical techniques. Results revealed that majority of the fishermen were married (98.9%), in the age bracket of 41-60 years (71.1%) with mean age of 49 years, had household size of 6-15 persons (91.1%) with mean household size being 9 persons, from extended families (90.0%), either either no formal (43.3%) or only primary education (41.1%), were non-members of social groups (62.2%), and had no other occupations (93.3%). It was also reported that there was generally low level of household livelihood diversification across the fishing communities. Gill nets were the most commonly used fishing gears across the fishing communities (80.0%). This was followed by seine nets (63.3%), traps (56.7%) and trawl nets (53.3%) while fish aggregating devices (35.6%), cast nets (37.8%) and hook and line (24.4%) were the least used fishing gears in the study locations. Results further revealed that coastal fishery was characterised by conflicts among water users (64.4%), absence of protected fishing areas (81.1%), and experience of water pollution (36.7%). Majority (71.1%) of the fishermen across the study locations agreed with closed season policy as a coastal fisheries conservation strategy. This was followed by gear restriction (30.0%). Results of Chi-square analysis revealed that there were significant associations between level of household livelihood diversification and fishermen’s agreement with gear restriction (χ2 = 15.545, df = 5), and closed season (χ2 = 11.214, df = 4). The study concluded that coastal fisheries is in a poor state and that it could be improved through the introduction of gear restriction and closed season policies. The study recommended that youths in the coastal areas should venture into fishing, and that government and non-governmental agencies should organize sensitization programmes on fisheries conservation policies across the coastal areas in Ogun State. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastal" title="coastal">coastal</a>, <a
