Fish can survive inside/outside of water medium within a certain time. By knowing the level of survival fish at outside of water medium, a person can transport the fish to a place with more efficiently. Transport of live fish from one place to another can be done with wet and dry media system. In this experiment the treatment-given the observed differences in fish species. This experiment aimed to test the degree of resilience of fish out of water media. Based on the ANOVA table is obtained, it can be concluded that the type of fish affects the level of resilience of fish outside the water (Fhit> Ftab). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fish" title="fish">fish</a>, <a href="https://publications.waset.org/abstracts/search?q=transport" title=" transport"> transport</a>, <a href="https://publications.waset.org/abstracts/search?q=retention%20rate" title=" retention rate"> retention rate</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20resiliance" title=" fish resiliance "> fish resiliance </a> </p> <a href="https://publications.waset.org/abstracts/12212/the-resistance-of-fish-outside-of-water-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12212.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">336</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">17456</span> Effect of Different Model Drugs on the Properties of Model Membranes from Fishes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kumpugdee-Vollrath">M.

Srivastav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rohu (Labeo rohita) is an Indian major carp and highly relished freshwater food for its unique flavor, texture, and culinary properties. It is highly perishable and, spoilage occurs as a result of series of complicated biochemical changes brought about by enzymes which are the function of time and storage temperature also. The influence of storage temperature (5, 0, and -5 °C) on colour and texture of fish were studied during 14 days storage period in order to analyze kinetics of colour and textural changes. The rate of total colour change was most noticeable at the highest storage temperature (5°C), and these changes were well described by the first order reaction. Texture is an important variable of quality of the fish and is increasing concern to aquaculture industries. Textural parameters such as hardness, toughness and stiffness were evaluated on a texture analyzer for the different day of stored fish. The significant reduction (P ≤ 0.05) in hardness was observed after 2nd, 4th and 8th day for the fish stored at 5, 0, and -5 °C respectively. The textural changes of fish during storage followed a first order kinetic model and fitted well with this model (R2 > 0.95). However, the textural data with respect to time was also fitted to modified Maxwell model and found to be good fit with R2 value ranges from 0.96 to 0.98. Temperature dependence of colour and texture change was adequately modelled with the Arrhenius type equation. This fitted model may be used for the determination of shelf life of Rohu Rohu (Labeo rohita) Fish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=first%20order%20kinetics" title="first order kinetics">first order kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=biochemical%20changes" title=" biochemical changes"> biochemical changes</a>, <a href="https://publications.waset.org/abstracts/search?q=Maxwell%20model" title=" Maxwell model"> Maxwell model</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour"> colour</a>, <a href="https://publications.waset.org/abstracts/search?q=texture" title=" texture"> texture</a>, <a href="https://publications.waset.org/abstracts/search?q=Arrhenius%20type%20equation" title=" Arrhenius type equation"> Arrhenius type equation</a> </p> <a href="https://publications.waset.org/abstracts/57115/kinetic-modeling-of-colour-and-textural-properties-of-stored-rohu-labeo-rohita-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57115.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">234</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">17454</span> Comparative Analysis of Integrated and Non-Integrated Fish Farming in Ogun State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20G.%20Abiona">B.

Primary data were collected using interview guide. Random sampling techniques was used to select 133 non-integrated fish farmers (NIFF) and 216 integrated fish farmers (IFF) (n = 349) from the study area. Data were analyzed using Chi-square, T-test and Pearson Product moment correlation. Results showed that 92.5% of NIFF was male compared to IFF (90.7%). Also, 96.8% of IFF and 79.7% of NIFF were married. The mean ages of sampled farmers were 44 years (NIFF) and 46 years (IFF) while the mean fish farming experiences were 4 years (NIFF) and 5 years (IFF). Also, the average net profit per year of integrated fish farmers was ₦162,550 compared to NIFF (₦61,638). The chi-square analyses showed that knowledge of fish farming had significant relationship with respondents sex (χ2 = 9.44, df = 2, p < 0.05), age (r = 0.20, p< 0.05) and farming experience (r = p = 0.05). Significant differences exist between integrated and non-integrated fish farming, considering their knowledge of fish farming (t = 21.5, χ = 43.01, p < 0.05). The study concluded that IFF are more profitable compared to NIFF. It was recommended that private investors and NGOs should sponsor short training and courses which will enhance efficiency of fish farming to boost productivity among fish farmers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=profitability%20analysis" title="profitability analysis">profitability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=farms" title=" farms"> farms</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a> </p> <a href="https://publications.waset.org/abstracts/7469/comparative-analysis-of-integrated-and-non-integrated-fish-farming-in-ogun-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7469.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">336</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">17453</span> Clove Essential Oil Improves Lipid Peroxidation and Antioxidant Activity in Tilapia Fish Fillet Cooked by Grilling and Microwaving</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Oskoueian">E.

The tilapia fish considered as the third largest group of farmed fish. The oxidative deterioration of fish meat may occur during the cooking process. The proper cooking process and using natural antioxidant to prevent oxidation and enhance the quality of the tilapia fish fillet is necessary. Hence, this research was carried out to evaluate the potential of clove essential oil to prevent lipid peroxidation and enhance the antioxidant activity of tilapia fish fillet cooked using microwave and griller. The results showed that cooking using microwave significantly (p < 0.05) increased the lipid peroxidation and decreased the DPPH and ferric reducing activity power of the fish fillet as compared to grilling. The fortification of fish fillet using clove essential oil prevented from lipid peroxidation and enhanced the antioxidant activity of the fish fillet significantly (p < 0.05). Consequently, fortification of tilapia fish fillet using clove essential oil followed by cooking using griller to have high quality cooked fish meat is recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title="antioxidant activity">antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=fillet" title=" fillet"> fillet</a>, <a href="https://publications.waset.org/abstracts/search?q=fish" title=" fish"> fish</a>, <a href="https://publications.waset.org/abstracts/search?q=fortification" title=" fortification"> fortification</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20peroxidation" title=" lipid peroxidation"> lipid peroxidation</a> </p> <a href="https://publications.waset.org/abstracts/1537/clove-essential-oil-improves-lipid-peroxidation-and-antioxidant-activity-in-tilapia-fish-fillet-cooked-by-grilling-and-microwaving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1537.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">453</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">17452</span> Patterns in Fish Diversity and Abundance of an Abandoned Gold Mine Reservoirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20E.%20Obayemi">O.

The objective was to examined the fish assemblages of the reservoirs and provide more additional information on the reservoir. The fish species in the reservoirs comprised of twelve species of six families. The results of the study also showed that five species of fish were caught in reservoir five while ten fish species were captured in reservoir six. Species such as Malapterurus electricus, Ctenopoma kingsleyae, Mormyrus rume, Parachanna obscura, Sarotherodon galilaeus, Tilapia mariae, C. guntheri, Clarias macromystax, Coptodon zilii and Clarias gariepinus were caught during the sampling period. There was a significant difference (p=0.014, t = 1.711) in the abundance of fish species in the two reservoirs. Seasonally, reservoirs five (p=0.221, t = 1.859) and six (p=0.453, t = 1.734) showed there was no significant difference in their fish populations. Also, despite being impacted with gold mining the diversity indices were high when compared to less disturbed waterbodies. The study concluded that the environments recorded low abundant fish species which suggests the influence of mining on the abundance and diversity of fish species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igun" title="Igun">Igun</a>, <a href="https://publications.waset.org/abstracts/search?q=fish" title=" fish"> fish</a>, <a href="https://publications.waset.org/abstracts/search?q=Shannon-Wiener%20Index" title=" Shannon-Wiener Index"> Shannon-Wiener Index</a>, <a href="https://publications.waset.org/abstracts/search?q=Simpson%20index" title=" Simpson index"> Simpson index</a>, <a href="https://publications.waset.org/abstracts/search?q=Pielou%20index" title=" Pielou index"> Pielou index</a> </p> <a href="https://publications.waset.org/abstracts/173907/patterns-in-fish-diversity-and-abundance-of-an-abandoned-gold-mine-reservoirs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173907.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">106</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">17451</span> Higher Freshwater Fish and Sea Fish Intake Is Inversely Associated with Liver Cancer in Patients with Hepatitis B</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maomao%20Cao">Maomao Cao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and aims While the association between higher consumption of fish and lower liver cancer risk has been confirmed, however, the association between specific fish intake and liver cancer risk remains unknown. We aimed to identify the association between specific fish consumption and the risk of liver cancer. Methods: Based on a community-based seropositive hepatitis B cohort involving 18404 individuals, face to face interview was conducted by a standardized questionnaire to acquire baseline information. Three common fish types in this study were analyzed, including freshwater fish, sea fish, and small fish (shrimp, crab, conch, and shell). All participants received liver cancer screening, and possible cases were identified by CT or MRI. Multivariable logistic models were applied to estimate the odds ratio (OR) and 95% confidence intervals (CI). Multivariate multiple imputations were utilized to impute observations with missing values. Results: 179 liver cancer cases were identified. Consumption of freshwater fish and sea fish at least once a week had a strong inverse association with liver cancer risk compared with the lowest intake level, with an adjusted OR of 0.53 (95% CI, 0.38-0.75) and 0.38 (95% CI, 0.19-0.73), respectively. This inverse association was also observed after the imputation. There was no statistically significant association between intake of small fish and liver cancer risk (OR=0.58, 95%, CI 0.32-1.08). Conclusions: Our findings suggest that consumption of freshwater fish and sea fish at least once a week could reduce liver cancer risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-sectional%20study" title="cross-sectional study">cross-sectional study</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20intake" title=" fish intake"> fish intake</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20cancer" title=" liver cancer"> liver cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factor" title=" risk factor"> risk factor</a> </p> <a href="https://publications.waset.org/abstracts/139256/higher-freshwater-fish-and-sea-fish-intake-is-inversely-associated-with-liver-cancer-in-patients-with-hepatitis-b" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139256.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">273</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">17450</span> Determination of Cr Content in Canned Fish Marketed in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soheil%20Sobhanardakani">Soheil Sobhanardakani</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Vali%20Hosseini"> Seyed Vali Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Lima%20Tayebi"> Lima Tayebi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presence of heavy metals in the environment could constitute a hazard to food security and public health.

Samples of four popular brands of canned fish in the Iranian market (yellowfin tuna, common Kilka, Kawakawa, and longtail tuna) were analyzed for level of Cr after wet digestion with acids using graphite furnace atomic absorption spectrophotometry. The mean concentrations for Cr in the different brands were: 2.57, 3.24, 3.16, and 1.65 μg/g for brands A, B, C, and D respectively. Significant differences were observed in the Cr levels between all of the different brands of canned fish evaluated in this study. The Cr concentrations for the varieties of canned fishes were generally within the FAO/WHO, U.S. FDA, and U.S. EPA recommended limits for fish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title="heavy metals">heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20metals" title=" essential metals"> essential metals</a>, <a href="https://publications.waset.org/abstracts/search?q=canned%20fish" title=" canned fish"> canned fish</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security" title=" food security"> food security</a> </p> <a href="https://publications.waset.org/abstracts/19901/determination-of-cr-content-in-canned-fish-marketed-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19901.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">293</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">17449</span> Analysis of Hydraulic Velocity in Fishway Using CCHE2D Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Abbas%20Kamanbedast">Amir Abbas Kamanbedast</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20Mohammad%20Shafipor"> Masood Mohammad Shafipor</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Ghotboddin"> Amir Ghotboddin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fish way is a structure that in generally using to migrate to the place where they are spawned and is made near the spillway. Preventing fish spawning or migrating to their original place by fishway structures can affect their lives in the river or even erase one access to intended environment. The main objective of these structures is establishing a safe path for fish migration. In the present study first the hydraulic specifications of Hamidieh diversion dam were assessed and then it is problems were evaluated. In this study the dimensions of the fish way, including velocity of pools, were evaluated by CCHE2D software. Then by change slope in this structure streamlines like velocity in the pools were measured. For calibration can be use measuring local velocities in some pools. The information can be seen the fishway width of 0.3 m has minimum rate of descent in the total number of structures (pools and overflow). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fishway" title="fishway">fishway</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity" title=" velocity"> velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidieh-Diversion%20Dam" title=" Hamidieh-Diversion Dam"> Hamidieh-Diversion Dam</a>, <a href="https://publications.waset.org/abstracts/search?q=CCHE2D%20model" title=" CCHE2D model"> CCHE2D model</a> </p> <a href="https://publications.waset.org/abstracts/26983/analysis-of-hydraulic-velocity-in-fishway-using-cche2d-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26983.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">493</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">17448</span> Characterization of Fish Bone Catalyst for Biodiesel Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarina%20Sulaiman">Sarina Sulaiman</a>, <a href="https://publications.waset.org/abstracts/search?q=N.Khairudin"> N.Khairudin </a>, <a href="https://publications.waset.org/abstracts/search?q=P.Jamal"> P.Jamal</a>, <a href="https://publications.waset.org/abstracts/search?q=M.Z.%20Alam"> M.Z.

This study was done to promote the adoption of the fish solar tent dryers by the many small scale fish processors in Malawi through the assessment of the economic viability of these dryers. With the use of the project’s baseline survey data, a business model for a constructed ‘ready for use’ solar tent dryer was developed where investment appraisal techniques were calculated in addition with the sensitivity analysis. The study also conducted a risk analysis through the use of the Monte Carlo simulation technique and a probabilistic net present value was found. The investment appraisal results showed that the net present value was US$8,756.85, the internal rate of return was 62% higher than the 16.32% cost of capital and the payback period was 1.64 years. The sensitivity analysis results showed that only two input variables influenced the fish solar dryer investment’s net present value. These are the dried fish selling prices that were correlating positively with the net present value and the fresh fish buying prices that were negatively correlating with the net present value. Risk analysis results showed that the chances that fish processors will make a loss from this type of investment are 17.56%. It was also observed that there exist only a 0.20 probability of experiencing a negative net present value from this type of investment. Lastly, the study found that the net present value of the fish solar tent dryer’s investment is still robust in spite of any changes in the levels of investors risk preferences. With these results, it is concluded that the fish solar tent dryers in Malawi are an economically viable investment because they are able to improve the returns in the fish processing activity. As such, fish processors need to adopt them by investing their money to construct and use them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=investment%20appraisal" title="investment appraisal">investment appraisal</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20analysis" title=" risk analysis"> risk analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20analysis" title=" sensitivity analysis"> sensitivity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20tent%20drying" title=" solar tent drying"> solar tent drying</a> </p> <a href="https://publications.waset.org/abstracts/53136/economic-assessment-of-the-fish-solar-tent-dryers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53136.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">278</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">17446</span> Assessment of Landfill Pollution Load on Hydroecosystem by Use of Heavy Metal Bioaccumulation Data in Fish</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gintar%C4%97%20Sauliut%C4%97">Gintarė Sauliutė</a>, <a href="https://publications.waset.org/abstracts/search?q=Gintaras%20Svecevi%C4%8Dius"> Gintaras Svecevičius</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Landfill leachates contain a number of persistent pollutants, including heavy metals. They have the ability to spread in ecosystems and accumulate in fish which most of them are classified as top-consumers of trophic chains. Fish are freely swimming organisms; but perhaps, due to their species-specific ecological and behavioral properties, they often prefer the most suitable biotopes and therefore, did not avoid harmful substances or environments. That is why it is necessary to evaluate the persistent pollutant dispersion in hydroecosystem using fish tissue metal concentration. In hydroecosystems of hybrid type (e.g. river-pond-river) the distance from the pollution source could be a perfect indicator of such a kind of metal distribution. The studies were carried out in the Kairiai landfill neighboring hybrid-type ecosystem which is located 5 km east of the Šiauliai City. Fish tissue (gills, liver, and muscle) metal concentration measurements were performed on two types of ecologically-different fishes according to their feeding characteristics: benthophagous (Gibel carp, roach) and predatory (Northern pike, perch). A number of mathematical models (linear, non-linear, using log and other transformations) have been applied in order to identify the most satisfactorily description of the interdependence between fish tissue metal concentration and the distance from the pollution source. However, the only one log-multiple regression model revealed the pattern that the distance from the pollution source is closely and positively correlated with metal concentration in all predatory fish tissues studied (gills, liver, and muscle). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioaccumulation%20in%20fish" title="bioaccumulation in fish">bioaccumulation in fish</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroecosystem" title=" hydroecosystem"> hydroecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=landfill%20leachate" title=" landfill leachate"> landfill leachate</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a> </p> <a href="https://publications.waset.org/abstracts/38404/assessment-of-landfill-pollution-load-on-hydroecosystem-by-use-of-heavy-metal-bioaccumulation-data-in-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38404.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">286</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">17445</span> Effect of Chitosan and Ascorbic Acid Coating on the Refrigerated Tilapia Fish Fillet (Oreochromis niliticus)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jau-Shya%20Lee">Jau-Shya Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Rossita%20Shapawi"> Rossita Shapawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vin%20Cent%20Pua"> Vin Cent Pua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tilapia is a popular cultured fresh-water fish in Malaysia. The highly perishable nature of the fish and increasing demand for high-quality ready-to-cook fish has intensified the search for better fish preservation method. Chitosan edible coating has been evident to extend the shelf life of fish fillet. This work was attempted to explore the potential of ascorbic acid in enhancing the shelf life extension ability of chitosan coated Tilapia fillet under refrigeration condition (4 ± 1oC). A 3 2 Factorial Design which comprising of three concentrations of chitosan (1, 1.5 and 2%) and two concentrations of ascorbic acids (2.5 and 5%) was used. The fish fillets were analyzed for total viable count, thiobarbituric acid (TBA) value, pH, aw and colour changes at 3-day interval over 15-day storage. The shelf life of chitosan coated (1.5% and 2%) fillet was increased to 15 days as compared to uncoated fish fillet which can only last for nine days. The inhibition of microbial growth of fish fillet was enhanced with the addition of 5% of ascorbic acids in 2% of chitosan. The TBA value, pH and aw for chitosan coated samples were found lower than that of uncoated sample (p<0.05). The colour stability of the fish fillet was also improved by the composite coating. Overall, 2% of chitosan and 5% of ascorbic acid formed the most effective coating to enhance the quality and to lengthen the shelf life of refrigerated Tilapia fillet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ascorbic%20acid" title="ascorbic acid">ascorbic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=edible%20coating" title=" edible coating"> edible coating</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20fillet" title=" fish fillet"> fish fillet</a> </p> <a href="https://publications.waset.org/abstracts/74929/effect-of-chitosan-and-ascorbic-acid-coating-on-the-refrigerated-tilapia-fish-fillet-oreochromis-niliticus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74929.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">394</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">17444</span> Northern Westerrn Ghats of India Possess an Indigenous Fish Fauna: A Survey from Kudali River</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20A.%20Jamdade">R.

Tributaries of the Abbay and Tekeze Basins are supporting all life-requesting activities in Ethiopia. Fisheries of these habitats are also the mainstay of livelihoods. However, brutal human activities are affecting these ecosystems and the fish therein. This study was thus undertaken to examine fish distribution and community structure in relation to water parameters in Ayima, Gelegu and Shinfa Rivers. 2719 fish specimens identified into 43 species were sampled using gillnets, cast nets and electro-fishing on a seasonal campaign. Based on frequency of occurrence (%FO), 5 species fell in the ‘euconstant occurrence’ category or their FO was ≥75%, while many species were in the ‘constant occurrence’ category. Among others, site depth, total phosphorus, dissolved oxygen, and river channel diameter were key environmental factors determining fish community structure. Similarity percentage produced an overall average Bray-Curtis dissimilarity of 60.8% between the fish communities of the three rivers. The final model accounted for 77.2% of the total variance in fish composition, and all canonical axes were significant (Monte Carlo test 499, p =0.002). Generally, this study was conducted in areas where no ecological studies are undertaken, and the results obtained from this study could be important for the sustainable utilization of Ethiopian fisheries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fish%20biology" title="fish biology">fish biology</a>, <a href="https://publications.waset.org/abstracts/search?q=fisheries%20socioeconomics" title=" fisheries socioeconomics"> fisheries socioeconomics</a>, <a href="https://publications.waset.org/abstracts/search?q=aquatic%20biodiversity" title=" aquatic biodiversity"> aquatic biodiversity</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/190368/distribution-and-community-structure-of-fish-in-relation-with-water-physico-chemical-parameters-of-floodplain-rivers-in-the-alitash-national-park-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190368.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">29</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">17440</span> Counter-Current Extraction of Fish Oil and Toxic Elements from Fish Waste Using Supercritical Carbon Dioxide </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parvaneh%20Hajeb">Parvaneh Hajeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahram%20Shakibazadeh"> Shahram Shakibazadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Md.%20Zaidul%20Islam%20Sarker"> Md.

The aim of this study was to develop a method to extract oil from fish wastes with the least toxic elements contamination. Supercritical fluid extraction (SFE) was applied to detoxify fish oils from toxic elements. The SFE unit used consisted of an intelligent HPLC pump equipped with a cooling jacket to deliver CO2. The freeze-dried fish waste sample was extracted by heating in a column oven. Under supercritical conditions, the oil dissolved in CO2 was separated from the supercritical phase using pressure reduction. The SFE parameters (pressure, temperature, CO2 flow rate, and extraction time) were optimized using response surface methodology (RSM) to extract the highest levels of toxic elements. The results showed that toxic elements in fish oil can be reduced using supercritical CO2 at optimum pressure 40 MPa, temperature 61 ºC, CO2 flow rate 3.8 MPa, and extraction time 4.25 hr. There were significant reductions in the mercury (98.2%), cadmium (98.9%), arsenic (96%), and lead contents (99.2%) of the fish oil. The fish oil extracted using this method contained elements at levels that were much lower than the accepted limits of 0.1 μg/g. The reduction of toxic elements using the SFE method was more efficient than that of the conventional methods due to the high selectivity of supercritical CO2 for non-polar compounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title="food safety">food safety</a>, <a href="https://publications.waset.org/abstracts/search?q=toxic%20elements" title=" toxic elements"> toxic elements</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20oil" title=" fish oil"> fish oil</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20carbon%20dioxide" title=" supercritical carbon dioxide"> supercritical carbon dioxide</a> </p> <a href="https://publications.waset.org/abstracts/8379/counter-current-extraction-of-fish-oil-and-toxic-elements-from-fish-waste-using-supercritical-carbon-dioxide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8379.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">423</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">17439</span> Modulation of Fish Allergenicity towards the Production of a Low Allergen Farmed Fish</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denise%20Schrama">Denise Schrama</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Raposo"> Claudia Raposo</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Rodrigues"> Pedro Rodrigues</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Food allergies are conducted by a hypersensitive response of the immune system. These allergies are a global concern for the public health. Consumption of fish is increasing worldwide as it is a healthy meat with high nutritional value. Unfortunately, fish can cause adverse immune-mediate reactions, affecting part of the population with higher incidence in children. β-parvalbumin, a small, highly conserved stable, calcium or magnesium binding muscle protein is the main fish allergen. In fish-allergic patients, cross-reactivity between different fish species exist due to recognition of highly identical protein regions. Enolases, aldolases, or fish gelatin are other identified fish allergens in some fish species. With no available cure for fish allergies, clinical management is only based on an avoidance diet aiming at the total exclusion of offending food. Methods: Mediterranean fish (S. aurata and D. labrax) were fed specifically designed diets, enriched in components that target the expression or inactivation of parvalbumin (creatine and EDTA, respectively). After 90 days fish were sampled and biological tissues were excised. Proteomics was used to access fish allergens characterization and expression in muscle while IgE assays to confirm the lower allergenic potential are conducted in patients with history of fish allergies. Fish welfare and quality of flesh were established with biochemical, texture and sensorial analysis. Results: Fish welfare shows no major impact between diets. In case of creatine supplementation in D. labrax proteomic analysis show a slight decrease in parvalbumin expression. No accumulation of this compound was found in muscle. For EDTA supplementation in S. aurata IgE assay show a slight decrease in allergenicity when using sera of fish allergic patients. Conclusion: Supplementation with these two compounds seems to change slightly the allergenicity of the two mean Mediterranean species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fish%20allergies" title="fish allergies">fish allergies</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20nutrition" title=" fish nutrition"> fish nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=proteomics" title=" proteomics"> proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=aquaculture" title=" aquaculture"> aquaculture</a> </p> <a href="https://publications.waset.org/abstracts/93373/modulation-of-fish-allergenicity-towards-the-production-of-a-low-allergen-farmed-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93373.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">156</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">17438</span> Fermented Unripe Plantain (Musa paradisiacal) Peel Meal as a Replacement for Maize in the Diet of Nile Tilapia (Oreochromis niloticus) Fingerlings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20A.%20Bamidele">N.

Fingerlings (150) of Nile tilapia (1.70±0.1g) were stocked at 10 per plastic tank. Five iso-nitrogenous diets containing 40% crude protein in which maize meal was replaced by fermented unripe plantain peel meal at 0% (FUP0), 25% (FUP25), 50% (FUP50), 75% (FUP75) and 100% (FUP100) were formulated and prepared. The fingerlings were fed at 5% body weight per day for 56 days. There was no significant difference (p > 0.05) in all the growth parameters among the treatments. Feed conversion ratio of 1.35 in fish fed diet FUP25 was not significantly different (P > 0.05) from 1.42 of fish fed diet FUP0. Apparent protein digestibility of 86.94% in fish fed diet FUP100 was significantly higher (p < 0.05) than 70.37% in fish fed diet FUP0 while apparent carbohydrate of 88.34% in fish fed diet FUP0 was significantly different (p < 0.05) from 70.29% of FUP100. Red blood cell (4.30 ml/mm3) of fish fed diet FUP100 was not significantly different from 4.13 ml/mm3 of fish fed diet FUP50. The highest percentage profit of 88.85% in fish fed diet FUP100 was significantly higher than 66.68% in fish fed diet FUP0 while the profit index of 1.89 in fish fed diet FUP100 was significantly different from 1.67 in fish fed diet FUP0. Therefore, fermented unripe plantain peel meal can completely replace maize in the diet of O. niloticus fingerlings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fermentation" title="fermentation">fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20diets" title=" fish diets"> fish diets</a>, <a href="https://publications.waset.org/abstracts/search?q=plantain%20peel" title=" plantain peel"> plantain peel</a>, <a href="https://publications.waset.org/abstracts/search?q=tilapia" title=" tilapia"> tilapia</a> </p> <a href="https://publications.waset.org/abstracts/25105/fermented-unripe-plantain-musa-paradisiacal-peel-meal-as-a-replacement-for-maize-in-the-diet-of-nile-tilapia-oreochromis-niloticus-fingerlings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25105.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">537</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">17437</span> Pilot Scale Deproteinization Study on Fish Scale Using Response Surface Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Bellali">Fatima Bellali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariem%20Kharroubi"> Mariem Kharroubi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fish scale wastes are one of the main sources of production of value-added products such as collagen.

A comparative analysis of the quality of Diplotaxodon (Ndunduma) from Lake Malawi processed in solar tent dryer and open sun drying was conducted using proximate analysis, microbial analysis and sensory evaluation. Proximates for solar tent dried fish and open sun dried fish in terms of proteins, fats, moisture and ash were 63.3±0.15% and 63.3±0.34%, 19.6±0.09% and 19.9±0.25%, 8.3±0.12% and 17.0±0.01%, and 15.6±0.61% and 21.9±0.91% respectively. Crude protein and crude fat showed non-significant differences (p = 0.05), while moisture and ash content were significantly different (p = 001). Open sun dried fish had significantly higher numbers of viable bacteria counts (5.2×10⁶ CFU) than solar tent dried fish (3.9×10² CFU). Most isolated bacteria from solar tent dried and open sun dried fish were 1.0×10¹ and 7.2×10³ for Total coliform, 0 and 4.5 × 10³ for Escherishia coli, 0 and 7.5 × 10³ for Salmonella, 0 and 5.7×10² for shigella, 4.0×10¹ and 6.1×10³ for Staphylococcus, 1.0×10¹ and 7.0×10² for vibrio. Qualitative evaluation of sensory properties showed higher acceptability of 3.8 for solar tent dried fish than 1.7 for open sun dried fish. It is concluded that promotion of solar tent drying in processing small fish species in Malawi would support small-scale fish processors to produce quality fish in terms of nutritive value, reduced microbial contamination, sensory acceptability and reduced moisture content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diplotaxodon" title="diplotaxodon">diplotaxodon</a>, <a href="https://publications.waset.org/abstracts/search?q=Malawi" title=" Malawi"> Malawi</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20sun%20drying" title=" open sun drying"> open sun drying</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20tent%20drying" title=" solar tent drying"> solar tent drying</a> </p> <a href="https://publications.waset.org/abstracts/53029/quality-analysis-of-lake-malawis-diplotaxodon-fish-species-processed-in-solar-tent-dryer-versus-open-sun-drying" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53029.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">336</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">17435</span> Fish Scales as a Nonlethal Screening Tools for Assessing the Effects of Surface Water Contaminants in Cyprinus Carpio</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahid%20Mahboob">Shahid Mahboob</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Muhammad%20Ashraf"> Hafiz Muhammad Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Salma%20Sultana"> Salma Sultana</a>, <a href="https://publications.waset.org/abstracts/search?q=Tayyaba%20Sultana"> Tayyaba Sultana</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Al-Ghanim"> Khalid Al-Ghanim</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahid%20Al-Misned"> Fahid Al-Misned</a>, <a href="https://publications.waset.org/abstracts/search?q=Zubair%20Ahmedd"> Zubair Ahmedd</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is an increasing need for an effective tool to estimate the risks derived from the large number of pollutants released to the environment by human activities. Typical screening procedures are highly invasive or lethal to the fish. Recent studies show that fish scales biochemically respond to a range of contaminants, including toxic metals, organic compounds, and endocrine disruptors. The present study evaluated the effects of the surface water contaminants on Cyprinus carpio in the Ravi River by comparing DNA extracted non-lethally from their scales to DNA extracted from the scales of fish collected from a controlled fish farm. A single, random sampling was conducted. Fish were broadly categorised into three weight categories (W1, W2 and W3). The experimental samples in the W1, W2 and W3 categories had an average DNA concentration (µg/µl) that was lower than the control samples. All control samples had a single DNA band; whereas the experimental samples in W1 fish had 1 to 2 bands, the experimental samples in W2 fish had two bands and the experimental samples in W3 fish had fragmentation in the form of three bands. These bands exhibit the effects of pollution on fish in the Ravi River. On the basis findings of this study, we propose that fish scales can be successfully employed as a new non-lethal tool for the evaluation of the effect of surface water contaminants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fish%20scales" title="fish scales">fish scales</a>, <a href="https://publications.waset.org/abstracts/search?q=Cyprinus%20carpio" title=" Cyprinus carpio"> Cyprinus carpio</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive" title=" non-invasive"> non-invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20fragmentation" title=" DNA fragmentation"> DNA fragmentation</a> </p> <a href="https://publications.waset.org/abstracts/28624/fish-scales-as-a-nonlethal-screening-tools-for-assessing-the-effects-of-surface-water-contaminants-in-cyprinus-carpio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28624.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">414</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">17434</span> An Economic Study for Fish Production in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20Elsayed%20Elkheshin">Manal Elsayed Elkheshin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Saleh%20Mansour"> Rasha Saleh Mansour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Fawzy%20Mohamed%20Eldnasury"> Mohamed Fawzy Mohamed Eldnasury</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamdouh%20Elbadry%20Mohamed"> Mamdouh Elbadry Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research Aims to identify the main factors affecting the production and the fish consumption in Egypt, through the econometric estimation for various forms functions of fish production and fish consumption during the period (1991-2014), as the aim of this research to forecast the production and the fish consumption in Egypt until 2020, through determine the best standard methods using (ARIMA).This research also aims to the economic feasibility of the production of fish in aquaculture farms study; investment cost and represents the value of land, buildings, equipment and irrigation. Aquaculture requires three types of fish (Tilapia, carp fish, and mullet fish), and the total area of the farm, about an acre. The annual Fish production from this project about 3.5 tons.

The fish processing industry generates a considerable amount of by-products which represents a considerable environmental problem. Accordingly, the reuse and valorisation of these by-products is a key process for marine resource preservation. The significant volume of fish waste produced worldwide, along with its environmental impact, underscores the urgent need for the adoption of sustainable practices. The transformative potential of utilizing fish processing waste to create industrial value is gaining recognition. The substantial amounts of waste generated by the fish processing industry present both environmental challenges and economic inefficiencies. Different added-value products can be recovered by the valorisation industries, whereas fishing companies can save costs associated with the management of those wastes, with associated advantages, not only in terms of economic income but also considering the environmental impacts. Fish processing by-products have numerous applications; the target portfolio of products will be fish oil, fish protein hydrolysates, bacteriocins, pigments, vitamins, collagen, and calcium-rich powder, targeting food products, additives, supplements, and nutraceuticals. This literature review focuses on the main valorisation ways of fish wastes and different compounds with a high commercial value obtained by fish by-products and their possible applications in different fields. Highlighting its potential in sustainable resource management strategies can play and important role in reshaping the fish processing industry, driving it towards circular economy and consequently more sustainable future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fish%20process%20industry" title="fish process industry">fish process industry</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20wastes" title=" fish wastes"> fish wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=by-products" title=" by-products"> by-products</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20economy" title=" circular economy"> circular economy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/192280/valorization-cascade-approach-of-fish-by-products-towards-a-zero-waste-future-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192280.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">17</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">17432</span> Analyzing the Support to Fisheries in the European Union: Modelling Budgetary Transfers in Wild Fisheries </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Angulo">Laura Angulo</a>, <a href="https://publications.waset.org/abstracts/search?q=Petra%20Salamon"> Petra Salamon</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Banse"> Martin Banse</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Storkamp"> Frederic Storkamp</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fisheries subsidies are focus on reduce management costs or deliver income benefits to fishers. In 2015, total fishery budgetary transfers in 31 OECD countries represented 35% of their total landing value. However, subsidies to fishing have adverse effects on trade and it has been claimed that they may contribute directly to overfishing. Therefore, this paper analyses to what extend fisheries subsidies may 1) influence capture production facing quotas and 2) affect price dynamics. The study uses the fish module in AGMEMOD (Agriculture Member States Modelling, details see Chantreuil et al. (2012)) which covers eight fish categories (cephalopods; crustaceans; demersal marine fish; pelagic marine fish; molluscs excl. cephalopods; other marine finfish species; freshwater and diadromous fish) for EU member states and other selected countries developed under the SUCCESS project. This model incorporates transfer payments directly linked to fisheries operational costs. As aquaculture and wild fishery are not included within the WTO Agreement on Agriculture, data on fisheries subsidies is obtained from the OECD Fisheries Support Estimates (FSE) database, which provides statistics on budgetary transfers to the fisheries sector. Since support has been moving from budgetary transfers to General Service Support Estimate the last years, subsidies in capture production may not present substantial effects. Nevertheless, they would still show the impact across countries and fish categories within the European Union. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AGMEMOD" title="AGMEMOD">AGMEMOD</a>, <a href="https://publications.waset.org/abstracts/search?q=budgetary%20transfers" title=" budgetary transfers"> budgetary transfers</a>, <a href="https://publications.waset.org/abstracts/search?q=EU%20Member%20States" title=" EU Member States"> EU Member States</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20model" title=" fish model"> fish model</a>, <a href="https://publications.waset.org/abstracts/search?q=fisheries%20support%20estimate" title=" fisheries support estimate"> fisheries support estimate</a> </p> <a href="https://publications.waset.org/abstracts/76330/analyzing-the-support-to-fisheries-in-the-european-union-modelling-budgetary-transfers-in-wild-fisheries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76330.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">246</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">17431</span> Scanning Electron Microscopy of the Erythrocytes of Channa punctatus (Bloch) Exposed to Mercuric Chloride</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shweta%20Maheshwari">Shweta Maheshwari</a>, <a href="https://publications.waset.org/abstracts/search?q=Anish%20Dua"> Anish Dua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hematological changes reflect the adverse effects of heavy metals on fish. Hematology is a valuable tool to evaluate pathological condition of the fish. It helps in diagnosing the structural and functional status of fish exposed to toxicants. Morphological alteration in erythrocytes due to environmental stress can be studied through ultra-structural analysis. The aim of the present study was to assess the toxicity of mercuric chloride on red blood cells of an air breathing fish, Channa punctatus. Fish were subjected to chronic experiments using three sublethal concentration of mercuric chloride (0.020mg/L, 0.027mg/L, 0.040mg/L) for a period of 15, 30 and 60 days. Exposed fish of all the three concentrations were subjected to a recovery period of 30 days. A control was maintained in tap water simultaneously. For SEM analysis, blood from caudal vein of fish was taken and examined at an accelerating voltage of 20kV. Scanning electron micrographs revealed elliptical shaped erythrocytes of control fish. Alterations in the erythrocyte morphology such as presence of spherocytes, membrane internalization, crenation of membrane and development of lobopodial projections were observed in the exposed fish. The study revealed that ultra-structural analysis appears to be a sensitive method to evaluate the toxicity of various toxicants to fish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Channa%20punctatus" title="Channa punctatus">Channa punctatus</a>, <a href="https://publications.waset.org/abstracts/search?q=erythrocytes" title=" erythrocytes"> erythrocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=mercuric%20chloride" title=" mercuric chloride"> mercuric chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscopy" title=" scanning electron microscopy"> scanning electron microscopy</a> </p> <a href="https://publications.waset.org/abstracts/37384/scanning-electron-microscopy-of-the-erythrocytes-of-channa-punctatus-bloch-exposed-to-mercuric-chloride" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37384.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">371</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">17430</span> Radiological Assessment of Fish Samples Due to Natural Radionuclides in River Yobe, North Eastern Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20T.%20Abba">H.

Radioactivity is phenomenon that leads to production of radiations, whereas radiation is known to trigger or induce cancer. The fish were analyzed to estimate the radioactivity (activity) concentrations due to natural radionuclides (Radium 222(226Ra), Thorium 232 (232Th) and Potassium 40 (40K)). The obtained result show that the activity concentration for (226Ra), in all the fish samples collected ranges from 15.23±2.45 BqKg-1 to 67.39±2.13 BqKg-1 with an average value of 34.13±1.34 BqKg-1. That of 232Th, ranges from 42.66±0.81 BqKg-1 to 201.18±3.82 BqKg-1, and the average value stands at 96.01±3.82 BqKg-1. The activity concentration for 40K, ranges between 243.3±1.56 BqKg-1 to 618.2±2.81 BqKg-1 and the average is 413.92±1.7 BqKg-1. This study indicated that average daily intake due to natural activity from the fish is valued at 0.913 Bq/day, 2.577Bq/day and 11.088 Bq/day for 226Ra, 232Th and 40K respectively. This shows that the activity concentration values for fish, shows a promising result with most of the fish activity concentrations been within the acceptable limits. However locations (F02, F07 and F12) fish, became outliers with significant values of 112.53μSvy-1, 121.11μSvy-1 and 114.32μSvy-1 effective Dose. This could be attributed to variation in geological formations within the river as while as the feeding habits of these fish. The work shows that consumers of fish from River Yobe have no risk of radioactivity ingestion, even though no amount of radiation is assumed to be totally safe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radiation" title="radiation">radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=radio-activity" title=" radio-activity"> radio-activity</a>, <a href="https://publications.waset.org/abstracts/search?q=dose" title=" dose"> dose</a>, <a href="https://publications.waset.org/abstracts/search?q=radionuclides" title=" radionuclides"> radionuclides</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20Yobe" title=" river Yobe "> river Yobe </a> </p> <a href="https://publications.waset.org/abstracts/12312/radiological-assessment-of-fish-samples-due-to-natural-radionuclides-in-river-yobe-north-eastern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12312.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">318</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">17429</span> Genotoxicity of 4-Nonylphenol (4NP) on Oreochromus spilurs Fish</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20Alsharif">M. M. Alsharif </a> </p> <p class="card-text"><strong>Abstract:</strong></p> 4-Nonylphenol Compound is widely used as an element of detergents, paints, insecticides and many others products. It is known that the existence of this compound may lead to the emission of estrogenic responses in mammals, birds and fish. It is described as pollutant since it causes disorder of endocrine glands. In previous studies, it was proven that this compound exists in water and in the materials precipitated in Red Sea coast in Jeddah near the drains of processed drainage water and near the drainage site of the residuals of paper factories. Therefore, this study aimed to evaluate the cytogenetic aberrations caused by 4-nonylphenol through exposing Talapia Fishes to aquatic solution of the compound with 0, 15, 30 microgram/liter for one month. Samples of gills and liver were collected for micronuclei, nuclear abnormalities and measuring DNA and RNA amount in the treated fish. The results pointed out that there is a significant increase in the numbers of micronuclei in the fish exposed to the former concentrations as compared to the control group. Exposing fishes to 4-nonylphenol resulted in an increased amount of both DNA and RNA, compared to the control group. There is a positive correlation between the amount of the compound (i.e. dosage dependent effect) and the inspiring for cytogenetic effect on Talapia fishes in Jeddah. Therefore, micronucleus test, DNA and RNA contents can be considered as an index of cumulative exposure, which appear to be a sensitive model to evaluate genotoxic effects of 4-Nonylphenol compound on fish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genotoxic" title="genotoxic">genotoxic</a>, <a href="https://publications.waset.org/abstracts/search?q=4-nonylphenol" title=" 4-nonylphenol"> 4-nonylphenol</a>, <a href="https://publications.waset.org/abstracts/search?q=micronuclei" title=" micronuclei"> micronuclei</a>, <a href="https://publications.waset.org/abstracts/search?q=fish" title=" fish"> fish</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA" title=" DNA"> DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=RNA" title=" RNA"> RNA</a> </p> <a href="https://publications.waset.org/abstracts/6220/genotoxicity-of-4-nonylphenol-4np-on-oreochromus-spilurs-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6220.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">308</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">17428</span> The Concentration of Natural Alpha Emitters Radionuclides in Fish and Their Contribution to the Internal Dose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wagner%20Pereira">Wagner Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Alphonse%20Kelecom"> Alphonse Kelecom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mining can impact the environment, and the major impact of some mining activities is the radiological impact. In human populations, such impact is well studied and regulated. For biota, this assessment always had as focus the protection of human food chain. The protection of biota itself is a new approach, still developing. In order to contribute to this new approach, fish collecting was carried out in areas of naturally occurring radioactive materials (NORM), where a uranium mine is in decommissioning phase. The activity concentrations were analyzed, in Bq/kg wet weight, for Uranium (Unat), Th-232 and Ra-226 in the lambari fish Astyanax bimaculatus L. (omnivorous fish) and in the traíra fish Hoplias malabaricus Bloch, 1794 (carnivorous fish). Seven composite samples (that is: a sufficient number of individuals to reach at least 2 kg of fresh weight) were collected every six months between 2013 and 2015. The mean activity concentrations (AC) for uranium ranged from 1.12 (lambari) to 0.60 (lungfish). For Th, variations ranged from 0.30 to 0.05 (lambari and traíra, respectively). Finally, the Ra-226 means ranged between 0.08 and 0.03. No temporal trends of accumulation could be identified. Systematically, the AC values of radionuclides were higher in omnivorous fish when compared to the carnivore ones. <p class="card-text"><strong>Keywords:</strong> <a
