It must work actively not just to create value for the consumer, but to involve the consumer in co-creating value for shrimp product innovation in the market. In this theoretical work, we conceptualize the business concept of value co-creation in the context of shrimp products, and propose a framework of value co-creation for shrimp product innovation in shrimp industries. With guidance on value co-creation in in shrimp industry, and shrimp value chain actors mapped to the co-creation cycle, companies can use the framework to offer new shrimp product to consumer communities. Although customer co-creation is known approach in the world, it is not commonly used by the companies in Bangladesh. This paper makes an original contribution by conceptualizing co-creation and set the examples of best co-creation practices in food sector. The results of the study provide management with guidelines for successful co-creation projects with an innovation- and market-oriented approach. The framework also provides a basis for further research in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bangladesh" title="bangladesh">bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp%20industry" title=" shrimp industry"> shrimp industry</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20co-creation" title=" value co-creation"> value co-creation</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp%20product" title=" shrimp product "> shrimp product </a> </p> <a href="https://publications.waset.org/abstracts/30628/conceptualization-of-value-co-creation-for-shrimp-products-in-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30628.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">514</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">86</span> The Determination of Total Microbial Count and Prevalence of Salmonella in the Shrimp Supply in Khuzestan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sana%20Mohammad%20Jafar">Sana Mohammad Jafar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Salmonella is one of the major causes of foodborne diseases throughout the world. Shrimp are an important commodity in world fishery trade. The microbiological quality of shrimp must be evaluated for assurance of shrimp. The aim of this study was to evaluate the microbiological quality and to determine the prevalence of Salmonella in shrimp sold in Khuzestan province. In this study, a total of 245 samples of shrimp sold in Khuzestan province were tested for Salmonella prevalence and total microbial population. The mean aerobic bacterial count in 50.2% of samples was 2200, in 29.8% of samples was 13,600, in 20% of samples was 36,700, and the mean aerobic bacterial count in the total samples was 20,000. (20,000 cfu/cc). Of the total samples, 33 samples were positive for Salmonella and the prevalence of Salmonella was determined 13.4%. These results indicate the possibility that shrimp contribute to foodborne infections. The improvement of shrimp quality is an important issue, and shrimp before consuming should be washed with water containing chlorine, with the aim of increasing safety. In addition, it should be avoided to eat shrimp as raw or not cooked properly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=determination" title="determination">determination</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20microbial" title=" total microbial"> total microbial</a>, <a href="https://publications.waset.org/abstracts/search?q=Salmonella" title=" Salmonella"> Salmonella</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp" title=" shrimp"> shrimp</a> </p> <a href="https://publications.waset.org/abstracts/92848/the-determination-of-total-microbial-count-and-prevalence-of-salmonella-in-the-shrimp-supply-in-khuzestan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92848.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">240</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">85</span> Effect of Non-Tariff Measures to Indonesian Shrimp Export in International Market: Case of Sanitary and Phytosanitary and Technical Barriers to Trade</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Khaliqi">Muhammad Khaliqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amzul%20Rifin"> Amzul Rifin</a>, <a href="https://publications.waset.org/abstracts/search?q=Andriyono%20Kilat%20Adhi"> Andriyono Kilat Adhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The non-tariff policy could make Indonesian shrimp exports decrease in the international market.

Experimental groups of shrimp with average initial body weight (2.43 ± 0.54 g) were fed each with 4 isonitrogeneous (38% crude protein) diets formulated to include 0, 25, 50 and 100% (diets 1 to 4, respectively) of fish meal substituted with mealworm. After eight weeks of feeding trials, shrimp fed with diet 3 and 4 revealed the highest values for live weight gain(8.01 ± 2.51 and 7.93 ± 1.12), specific growth rates (2.70 ± 1.12 and 2.59 ± 0.51) as well as better feed conversion ratio (2.69 ± 0.09 and 2.72 ± 0.19) compared to the control group with statistically significant manner (p<0.05). Survival range was 98% in all the treatments. An increase in weight gain and other growth associated parameters was observed with higher replacement. These results clearly indicate that 50% and 100% of fish meal protein in shrimp diet can be replaced by mealworm not only without any adverse effect but also the effect of promoting growth performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mealworm" title="mealworm">mealworm</a>, <a href="https://publications.waset.org/abstracts/search?q=Litopenaeus%20vannamei" title=" Litopenaeus vannamei"> Litopenaeus vannamei</a>, <a href="https://publications.waset.org/abstracts/search?q=Tenebrio%20molitor" title=" Tenebrio molitor"> Tenebrio molitor</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20shrimp" title=" white shrimp"> white shrimp</a> </p> <a href="https://publications.waset.org/abstracts/26041/nutritive-advantage-of-mealworm-tenebrio-molitor-in-the-diet-of-white-shrimp-litopenaeus-vannamei" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26041.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">470</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">81</span> Improvement of Protein Extraction From Shrimp by Product Used for Electrospinning by Applying Emerging Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20P%C3%A9rez-Won">Mario Pérez-Won</a>, <a href="https://publications.waset.org/abstracts/search?q=Vilbett%20Briones%20L."> Vilbett Briones L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Guido%20Trautmann"> Guido Trautmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Jos%C3%A9%20Bugue%C3%B1o"> María José Bugueño</a>, <a href="https://publications.waset.org/abstracts/search?q=Gipsy%20Tabilo-Munizaga"> Gipsy Tabilo-Munizaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Gonzalez-Cavieres"> Luis Gonzalez-Cavieres</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fishing industry generates a significant amount of shrimp byproducts, which often result in environmental contamination. Protein extraction from these by-products is a potential solution to minimize waste and revalue the by-products. To improve the extraction of proteins (by chemical method) from shrimp (Pleuroncodes monodon) by-products, the emerging technologies of ohmic heating (OH), microwaves (MW) and pulsed electric fields (PEF) were used. The results show that microwaves, electrical pulses, and ohmic heating improved performance by 28.19%, 19.25%, and 3.65%, respectively. Furthermore, conformational changes were studied by DSC and FTIR. Subsequently, the use of these proteins in electrospinning technology was evaluated. In conclusion, this study demonstrates that the application of emerging technologies, can significantly improve the extraction yield of proteins from shrimp by-products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title="electrospinning">electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20technologies" title=" emerging technologies"> emerging technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=improving%20extraction" title=" improving extraction"> improving extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp%20by-products" title=" shrimp by-products"> shrimp by-products</a> </p> <a href="https://publications.waset.org/abstracts/170663/improvement-of-protein-extraction-from-shrimp-by-product-used-for-electrospinning-by-applying-emerging-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170663.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">77</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">80</span> Isolation and Characterization White Spot Syndrome Protein Envelope Protein 19 from Black Tiger Shrimp (Penaeus monodon)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andi%20Aliah%20Hidayani">Andi Aliah Hidayani</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmi%20Citra%20Malina%20A.%20R.%20Tassakka"> Asmi Citra Malina A.

However, now this shrimp more death due to virus attack such as white spot disease caused by white spot syndrome virus (WSSV). Various efforts have done to prevent the disease, like immunostimulatory, probiotics, and vaccine. White spot syndrome virus (WSSV) envelope protein VP19 gene is important because of its involvement in the system infection of shrimp. This study aimed to isolate and characterize an envelope protein VP19 – encoding gene of WSSV using WSSV infected Vanname Shrimp sample from some areas in South Sulawesi (Pangkep, Barru and Pinrang). The genomic of DNA were isolated from shrimp muscle using DTAB-CTAB method. Isolation of gene encoding envelope protein VP19 WSSV ws successfully performed with the results of the length of DNA fragment was 387 bp.

However, the appearance of diseases that significantly affect the production of shrimps has been an obstacle for the shrimp industry. We hypothesized that natural fibers from biodiversity can stimulate the immune system to prevent shrimp diseases like vibriosis. In this project, we extracted the fibers from vegetal sources in Ecuador and characterized them using common techniques like XRD, SEM, and then we tested the effect of fibers as immunostimulants for shrimps in-vitro and in-vivo using small aquarium and large pools. Our results demonstrate that vegetal fibers can significantly increase the survival of shrimps. Moreover, the production of shrimps in a large pool was significantly increased. Lastly, the test of color and taste successfully surpass the control group of shrimps not treated with fiber food supplements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fibers" title="fibers">fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=immunostimulant" title=" immunostimulant"> immunostimulant</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp" title=" shrimp"> shrimp</a>, <a href="https://publications.waset.org/abstracts/search?q=vibriosis" title=" vibriosis"> vibriosis</a> </p> <a href="https://publications.waset.org/abstracts/117615/immunostimulant-from-biodiversity-to-enhance-shrimp-survival-against-vibriosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117615.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">157</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">78</span> Life Cycle Assesment (LCA) Study of Shrimp Fishery in the South East Coast of Arabian Sea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leela%20Edwin">Leela Edwin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rithin%20Joseph"> Rithin Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20H.%20Dhiju%20Das"> P.

Inventory data for the shrimp were collected over 1 year period and used to carry out a life cycle assessment (LCA). LCA was performed to assess and compare the environmental impacts associated with the fishing operations related to shrimp fishery. This analysis included the operation of the vessels, together with major inputs related to the production of diesel, trawl nets, or anti-fouling paints. Data regarding vessel operation was obtained from the detailed questionnaires filled out by 180 trawlers. The analysis on environmental impacts linked to shrimp extraction on a temporal scale, showed that varying landings enhanced the environmental burdens mainly associated with activities related to diesel production, transport and consumption of the fishing vessels. Discard rates for trawlers were also identified as a major environmental impact in this fishery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shrimp%20trawling" title="shrimp trawling">shrimp trawling</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assesment%20%28LCA%29" title=" life cycle assesment (LCA)"> life cycle assesment (LCA)</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabian%20sea" title=" Arabian sea"> Arabian sea</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts" title=" environmental impacts"> environmental impacts</a> </p> <a href="https://publications.waset.org/abstracts/39627/life-cycle-assesment-lca-study-of-shrimp-fishery-in-the-south-east-coast-of-arabian-sea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39627.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">323</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">77</span> Effect of Electromagnetic Fields on Protein Extraction from Shrimp By-Products for Electrospinning Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guido%20Trautmann-S%C3%A1ez">Guido Trautmann-Sáez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20P%C3%A9rez-Won"> Mario Pérez-Won</a>, <a href="https://publications.waset.org/abstracts/search?q=Vilbett%20Briones"> Vilbett Briones</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Jos%C3%A9%20Bugue%C3%B1o"> María José Bugueño</a>, <a href="https://publications.waset.org/abstracts/search?q=Gipsy%20Tabilo-Munizaga"> Gipsy Tabilo-Munizaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Gonz%C3%A1les-Cavieres"> Luis Gonzáles-Cavieres</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shrimp by-products are a valuable source of protein.

Shrimp samples in fresh condition were collected to perform the microbial assessment and 10 pathogenic isolates for antibiotic sensitivity test to 12 antibiotics. The results show that total bacterial count of all the samples were beyond the acceptable limit 105 cfu/g. In case of total coliform and E. coli density, no substantial difference (p<0.5) was found between the different shrimp samples from different districts and also high quantity of TC exceeding the limit (>102 cfu/g) proves the poor quality of shrimp. The FC abundance found in shrimps of Bagerhat and Satkhira was similar and significantly higher (p<0.5) than that of Khulna samples. No significant difference (p<0.5) was found among the high density of Salmonella-Shigella, Vibrio spp., and Staphylococcus spp. of the shrimp samples from the source places. In case of antibiotic sensitivity patterns, all of them were resistant to ampicillin, Penicillin and sensitive to kanamycin. Most of the isolates were frequently sensitive to ciprofloxacin and streptomycin in the sensitivity test. In case of nutritional composition, no significant difference (t-test, p<0.05) was found among protein, lipid, moisture and ash contents of shrimp samples. The findings prove that shrimp under this study was more or less contaminated and samples from Satkhira were highly privileged with food borne pathogens which confirmed the unhygienic condition of the shrimp farms as well as the presence of antibiotic resistance bacteria in shrimp fish supposed to threat food safety and deteriorate the export quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20borne%20pathogens" title="food borne pathogens">food borne pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=satkhira" title=" satkhira"> satkhira</a>, <a href="https://publications.waset.org/abstracts/search?q=penaeus%20indicus" title=" penaeus indicus"> penaeus indicus</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20sensitivity" title=" antibiotic sensitivity"> antibiotic sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=southwest%20Bangladesh" title=" southwest Bangladesh"> southwest Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title=" food safety"> food safety</a> </p> <a href="https://publications.waset.org/abstracts/2663/microbial-quality-assessment-of-indian-white-shrimp-penaeus-indicus-from-southwest-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2663.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">706</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">74</span> Application of Active Chitosan Coating Incorporated with Spirulina Extract as a Potential Food Packaging Material for Enhancing Quality and Shelf Life of Shrimp</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafik%20Balti">Rafik Balti</a>, <a href="https://publications.waset.org/abstracts/search?q=Nourhene%20Zayoud"> Nourhene Zayoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ben%20Mansour"> Mohamed Ben Mansour</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdellah%20Arhaliass"> Abdellah Arhaliass</a>, <a href="https://publications.waset.org/abstracts/search?q=Anthony%20Masse"> Anthony Masse</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Application of edible films and coatings with natural active compounds for enhancing storage stability of food products is a promising active packaging approach. Shrimp are generally known as valuable seafood products around the world because of their delicacy and good nutritional. However, shrimp is highly vulnerable to quality deterioration associated with biochemical, microbiological or physical changes during postmortem storage, which results in the limited shelf life of the product. Chitosan is considered as a functional packaging component for maintaining the quality and increasing the shelf life of perishable foods. The present study was conducted to evaluate edible coating of crab chitosan containing variable levels of ethanolic extract of Spirulina on microbiological (mesophilic aerobic, psychrotrophic, lactic acid bacteria, and enterobacteriacea), chemical (pH, TVB-N, TMA-N, PV, TBARS) and sensory (odor, color, texture, taste, and overall acceptance) properties of shrimp during refrigerated storage. Also, textural and color characteristics of coated shrimp were performed. According to the obtained results, crab chitosan in combination with Spirulina extract was very effective in order to extend the shelf life of shrimp during storage in refrigerated condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20packaging" title="food packaging">food packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=spirulina%20extract" title=" spirulina extract"> spirulina extract</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20shrimp" title=" white shrimp"> white shrimp</a>, <a href="https://publications.waset.org/abstracts/search?q=shelf%20life" title=" shelf life"> shelf life</a> </p> <a href="https://publications.waset.org/abstracts/108039/application-of-active-chitosan-coating-incorporated-with-spirulina-extract-as-a-potential-food-packaging-material-for-enhancing-quality-and-shelf-life-of-shrimp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108039.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">210</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">73</span> Diversification of Indonesian Terasi Shrimp (Acetes indicus) Powder as Alternative and Sustainable Food for the Double Burden of Malnutrition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Galuh%20Asri%20Bestari">Galuh Asri Bestari</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajar%20Shofiyya"> Hajar Shofiyya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Double burden of malnutrition (DBM) has been a global problem in these last decades occurs in both developed and developing countries. Overweight in adults and stunting among preschool children have dramatically increased and become the main problems of malnutrition that should be solved immediately since they are directly related with the health status and productivity. Reformulation of food product by using the local sea resources called terasi shrimp (Acetes indicus) has a potential possibility in facing the DBM. A study was carried out in Indonesia to determine the acceptability of terasi shrimp powder through sensory evaluation. Terasi shrimps were processed into powder form through sun drying and pounding methods. The powder form was directly added in food as alternative seasonings and tested among stunted and normal preschool children. Meanwhile, a further processing method is given to the shrimp powder tested in overweight and normal-weighed adults. The shrimp powder was mixed with sago flour and formed into balls, then steamed for 15-20 minutes, and finally served as alternative snacks. Based on the sensory evaluation, the shrimp powder has a good acceptance in taste (54%), shape (60%), and color properties (63%), while the shrimp balls has a good acceptance in size (65%), shape (50%), color (48%), taste (40%), and texture (36%). Terasi shrimp powder can be stored for a month in room temperature. In addition, carried out chemical analysis revealed that terasi shrimp (Acetes indicus) has higher percentage of protein, calcium, and iron than other animal sources, but conversely contains zero sodium and very low percentage of fat. Terasi shrimp’s shell also contains a substance called chitosan which acts by forming gels in the intestinal tract to entrap lipids, thus interfering with their absorption. After going through some processing methods, the shrimp powder and balls did not show any significant changes in their nutrient contents. So that, terasi shrimp powder is good to be consumed not only by overweight adults, but also by children to support their optimum growth. Intervention of terasi shrimp powder should be implemented step by step from national up to global governance program to face the DBM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Acetes%20indicus" title="Acetes indicus">Acetes indicus</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20food" title=" alternative food"> alternative food</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20burden%20of%20malnutrition" title=" double burden of malnutrition"> double burden of malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20evaluation" title=" sensory evaluation"> sensory evaluation</a> </p> <a href="https://publications.waset.org/abstracts/54582/diversification-of-indonesian-terasi-shrimp-acetes-indicus-powder-as-alternative-and-sustainable-food-for-the-double-burden-of-malnutrition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54582.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">305</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">72</span> Molecular Characterization of White Spot Syndrome Virus in Some Cultured Penaeid Shrimps of Coastal Regions in Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Baki%20Billah">Md.

This study was undermined to develop rapid detection method of WSSV. A total of shrimp samples 240 collected from the 12 shrimp farms of different coastal regions (Satkhira, Khulna, and Bagerhat) were analyzed by conventional PCR using VP28 and VP664 gene-specific primers. In satkhira, Bagerhat and Khulna 39, 41 and 29 samples were found WSSV positive respectively. Real-time PCR using 71-bp amplicon for VP664 gene correlated well with conventional PCR data. The prevalence rates of WSSV among the collected 240 samples were Satkhira 38%, Khulna 47% and Bagerhat 50%. Molecular analysis of the VP28 gene sequences of WSSV revealed that Bangladeshi strains phylogenetically affiliated to the strains belong to India. This work concluded that WSSV infections are widely distributed in the coastal regions cultured shrimp in Bangladesh.

Fish were collected from a local hatchery of Pulau Ketam, Selangor, Malaysia and immediately transferred to flow-through sea water system and subjected to four different temperatures (22, 26, 30, and 34 °C) and two diets (formulated pellet and shrimp). Body weight gain, food consumption, food conversion ratio, food consumption efficiency, specific growth rate, relative growth rate, daily growth rate, and gastric emptying period were significantly influenced by temperature and diet (P<0.05). The best food conversion ratio was with the shrimp group recorded at 30°C (1.33±0.08). The highest growth rate was observed in the shrimp group at 30°C (3.97±0.57% day-1), and the lowest was observed in the formulated pellet group at 22°C (1.63±0.29% day-1). No significant difference was observed between the groups subjected to temperatures of 26 and 30°C. Similarly, the lowest gastric emptying period was detected in the shrimp group at 30°C (16h), where the proportion of meal residues in the stomach decreased from 100% to less than 8% after 12h of starvation. A significantly longer gastric emptying period was observed in the formulated pellet group at 22°C (28h). Overall, the best results were observed on shrimp group subjected to a 30°C temperature. The data obtained from this study suggest that a shrimp diet fed on L. malabaricus at 30°C will optimize the commercial production of this commercially important fish species. <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=diet" title=" diet"> diet</a>, <a href="https://publications.waset.org/abstracts/search?q=digestion%20rate" title=" digestion rate"> digestion rate</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=Malabar%20blood%20snapper" title=" Malabar blood snapper"> Malabar blood snapper</a> </p> <a href="https://publications.waset.org/abstracts/78474/exploring-the-optimum-temperature-and-diet-for-growth-and-gastric-emptying-time-of-juvenile-malabar-blood-snapper-lutjanus-malabaricus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78474.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">68</span> The Ability of Organic Acids Production by Lactic Acid Bacteria in M17 Broth and Squid, Shrimp, Octopus, Eel Infusion Broth </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatih%20%C3%96zogul">Fatih Özogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Sezen%20%C3%96z%C3%A7eli%CC%87k"> Sezen Özçeli̇k</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20%C3%96zogul"> Yesim Özogul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lactic, acetic, succinic, propionic, formic and butyric acid production by lactic acid bacteria (LAB) were monitored in M17 broth (the control) and some fish (squid, shrimp, octopus, and eel) infusion broth by using HPLC method. There were significant differences in terms of lactic, acetic, succinic, propionic, formic and butyric acid production (p < 0.005) among bacterial strains. Acetic acid production was the lowest by LAB while succinic acid followed by propionic acid was synthesized at the highest levels. Lactic acid production ranged from 0 to 938 mg/L by all LAB strains in different infusion broth. The highest acetic acid production was found by Lb. acidophilus and Lb. delbrueckii subsp. lactic in octopus and shrimp infusion broth, with values of 872 and 674 mg/L, respectively while formic acid formation ranged from 1747 mg/L by Lb. acidophilus in octopus infusion broth to 69 mg/L by Lb. delbrueckii subsp. lactis in shrimp infusion broth. Propionic acid and butyric acid productions by St. thermophilus were 9852 and 3999 mg/L in shrimp infusion broth while Leu. mes. subsp. cremoris synthesized 312 and 9 mg/L of those organic acid in European squid infusion broth, respectively.

To discover the molecular mechanism of antiviral activity, the binding assay showed that SPIPm2 bind to the components of viral particle and shrimp hemocyte. From our previous report, viral target protein of SPIPm2 was identified, namely WSV477 using yeast two-hybrid screening. WSV477 is an early gene product of WSSV and involved in viral propagation. In this study, the co-immunoprecipitation technique and Tandem Mass Spectrometry (LC-MS/MS) was used to identify the target protein of SPIPm2 from shrimp hemocyte. The target protein of SPIPm2 was cyclophilin A. In vertebrate, cyclophilin A or peptidylprolyl isomerase A was reported to be the immune suppressor interacted with cyclosporin A involved in immune defense response. The recombinant cyclophilin A from Penaeus monodon (rPmCypA) was produced in E.coli system and purified using Ni-NTA column to confirm the protein-protein interaction. In vitro pull-down assay showed the interaction between rSPIPm2 and rPmCypA. To study the biological function of these proteins, the expression analysis of immune gene in shrimp defense pathways will be investigated after rPmCypA administration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyclophilin%20A" title="cyclophilin A">cyclophilin A</a>, <a href="https://publications.waset.org/abstracts/search?q=protein-protein%20interaction" title=" protein-protein interaction"> protein-protein interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazal-type%20serine%20proteinase%20inhibitor" title=" Kazal-type serine proteinase inhibitor"> Kazal-type serine proteinase inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=Penaeus%20monodon" title=" Penaeus monodon"> Penaeus monodon</a> </p> <a href="https://publications.waset.org/abstracts/40707/interaction-between-kazal-type-serine-proteinase-inhibitor-spipm2-and-cyclophilin-a-from-the-black-tiger-shrimp-penaeus-monodon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40707.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">236</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">66</span> Drying Characteristics of Shrimp by Using the Traditional Method of Oven</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20A.%20Simsek">I.

Currently, there has been an increasing interest in bioactive edible films and coatings to preserve the freshness and quality of foods. In this study, active edible coatings from microalgal exopolysaccharides (EPS) enriched with different concentrations of Red Seaweed Extract (RSE) (0.5, 1 and 1.5 % (w/v)) were developed and their effects on the quality changes of white shrimp during refrigerated storage (4 ± 1 °C) were examined over a period of 8 days. The control and the coated shrimp samples were analyzed periodically for microbiological (total viable bacteria, psychrotrophic bacteria, and enterobacteriaceae counts), chemical (pH, TVB-N, TMA-N, PV, TBARS), textural and sensory characteristics. The results indicated that the coating with a mixture of EPS and RSE could significantly decrease the total volatile basic nitrogen (TVB-N), trimethylamine (TMA) and thiobarbituric acid reactive substances (TBARS) (p < 0.05). With storage, EPS coatings containing RSE at both levels (1 and 1.5 %) were more effective in inhibiting the microbial species studied, specially psychrotrophic bacteria. Also, EPS + RSE coated samples had lower polyphenol oxidase (PPO) activity and lipid oxidation (p < 0.05) toward the end of storage. Textural and color properties of coated shrimp were generally more acceptable. Sensory scores indicated no significant changes in all samples during storage. The obtained results indicate that the edible EPS coating solutions enriched with RSE have noticeable effects on the quality and shelf life of shrimps when compared to control group. Finally, the present work demonstrates the effectiveness of EPS enriched coatings, offering a promising alternative to preserve more better the quality characteristics and to extend the shelf life of shrimp during the refrigerated storage <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20coating" title="active coating">active coating</a>, <a href="https://publications.waset.org/abstracts/search?q=exopolysaccharides" title=" exopolysaccharides"> exopolysaccharides</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20seaweed" title=" red seaweed"> red seaweed</a>, <a href="https://publications.waset.org/abstracts/search?q=refrigerated%20storage" title=" refrigerated storage"> refrigerated storage</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20shrimp" title=" white shrimp"> white shrimp</a> </p> <a href="https://publications.waset.org/abstracts/96247/active-exopolysaccharides-based-edible-coating-enriched-with-red-seaweed-gracilaria-gracilis-extract-for-improved-preservation-of-shrimp-quality-during-refrigerated-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96247.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">213</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">64</span> Effect of Bactocellon White Leg Shrimp (Litopenaeusvannamei) Growth Performance and the Shrimp Survival to Vibrio paraheamolyticus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Soltani">M.

The over-expressed mature recombinant (r)LvSWD exhibits antimicrobial activity against both Gram-positive and Gram-negative bacteria, especially VPAHPND. With four times the MIC of rLvSWD, the treated post larval shrimp infected by VPAHPND is able to survive longer with the 50% survival rate as long as 78 h as compared to 36 h of the infected shrimp without rLvSWD. To a certain extent, we have demonstrated that the rLvSWD can be applied to protect the post larval shrimp. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crustin" title="crustin">crustin</a>, <a href="https://publications.waset.org/abstracts/search?q=Litopenaeus%20vannamei" title=" Litopenaeus vannamei"> Litopenaeus vannamei</a>, <a href="https://publications.waset.org/abstracts/search?q=Vibrio%20parahaemolyticus%20AHPND" title=" Vibrio parahaemolyticus AHPND"> Vibrio parahaemolyticus AHPND</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/64929/antimicrobial-activity-of-a-single-wap-domain-swd-containing-protein-from-litopenaeus-vannamei-against-vibrio-parahaemolyticus-acute-hepatopancreatic-necrosis-disease-ahpnd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64929.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">216</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">62</span> Spinochromes: Kairomones Involved in the Symbiosis between the Shrimp Tuleariocaris holthuisi and Echinometra mathaei</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lola%20Brasseur">Lola Brasseur</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillaume%20Caulier"> Guillaume Caulier</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Demeyer"> Marie Demeyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascal%20Gerbaux"> Pascal Gerbaux</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Eeckhaut"> Igor Eeckhaut</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seawater being an ideal dispersing agent, chemical communication stays predominant in marine ecosystems. However, if many molecules acting in chemical heterospecific communication have already been well described in terrestrial ecosystems, only three of these molecules were identified in marine ecosystems. Echinoderms and their symbiotic organisms constitute very good models to study heterospecific chemical communication because each class synthesizes a specific type of molecules and symbioses with echinoderms as hosts are very usual. In this study, the chemical communication that allows the commensal shrimps Tuleariocaris holthuisi Hipeau-Jacquotte, 1965 to live with their host Echinometra mathaei (Blainville, 1825) was investigated. The chemoreception of the shrimp was characterized using olfactometers and it was demonstrated that hosts and synthetic hydroxynaphthoquinones are attractive to the symbiotic shrimps. Hydroxynaphthoquinonic pigments also known as spinochromes are by the way synthesized by sea urchin and involved in all probability in a lot of mechanisms. To our knowledge, this study is the first highlighting the ecological function of naphthoquinones as kairomones. Chemical extractions were also performed on sea urchins in order to analyze and identify their specific hydroxynaphthoquinones using HPLC-ESI-MS. Accurate mass identification and elemental composition have been performed on various organs (gonads, coelomic liquid, digestive system and test) in different morphotypes of Echinometra mathaei for a better understanding of the molecular diversity of these semiochemicals. Moreover, some experiments were performed to investigate the dependence of T. holthuisi for their host. First, the analyses showed that the molecules involved in shrimp pigmentation are the same that the ones involved in E. mathaei, suggesting a potential feeding on the host. Secondly, a substantial shrimp depigmentation and an increase of the mortality rate were demonstrated after the symbionts-host separation which could mean a potential implication of spinochromes in the shrimp metabolism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crustacean" title="crustacean">crustacean</a>, <a href="https://publications.waset.org/abstracts/search?q=sea%20urchin" title=" sea urchin"> sea urchin</a>, <a href="https://publications.waset.org/abstracts/search?q=spinochrome" title=" spinochrome"> spinochrome</a>, <a href="https://publications.waset.org/abstracts/search?q=symbiosis" title=" symbiosis"> symbiosis</a> </p> <a href="https://publications.waset.org/abstracts/55314/spinochromes-kairomones-involved-in-the-symbiosis-between-the-shrimp-tuleariocaris-holthuisi-and-echinometra-mathaei" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55314.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">191</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">61</span> Alignment between Governance Structures and Food Safety Standards on the Shrimp Supply Chain in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maharani%20Yulisti">Maharani Yulisti</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Mugera"> Amin Mugera</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Fogarty"> James Fogarty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food safety standards have received significant attention in the fisheries global market due to health issues, free trade agreements, and increasing aquaculture production. Vertical coordination throughout the supply chain of fish producing and exporting countries is needed to meet food safety demands imposed by importing countries. However, the complexities of the supply chain governance structures and difficulties in standard implementation can generate safety uncertainty and high transaction costs. Using a Transaction Cost Economics framework, this paper examines the alignment between food safety standards and the governance structures in the shrimp supply chain in Indonesia. We find the supply chain is organized closer to the hierarchy-like governance structure where private standard (organic standard) are implemented and more towards a market-like governance structure where public standard (IndoGAP certification) are more prevalent. To verify the statements, two cases are examined from Sidoarjo district as a centre of shrimp production in Indonesia. The results show that public baseline FSS (Food Safety Standards) need additional mechanism to achieve a coordinated chain-wide response because uncertainty, asset specificity, and performance measurement problems are high in this chain. Organic standard as private chain-wide FSS is more efficient because it has been achieved by hierarchical-like type of governance structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=governance%20structure" title="governance structure">governance structure</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp%20value%20chain" title=" shrimp value chain"> shrimp value chain</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20safety%20standards" title=" food safety standards"> food safety standards</a>, <a href="https://publications.waset.org/abstracts/search?q=transaction%20costs%20economics" title=" transaction costs economics"> transaction costs economics</a> </p> <a href="https://publications.waset.org/abstracts/80466/alignment-between-governance-structures-and-food-safety-standards-on-the-shrimp-supply-chain-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80466.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">379</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">60</span> Relationship between Monthly Shrimp Catch Rates and the Oceanography-Related Variables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussain%20M.%20Al-foudari">Hussain M.

Catches of P. semisulcatus were basically positively correlated with temperature, i.e., the higher the temperature, the higher the catch rate, while those of M. affinis and P. stylifera were negatively correlated with temperature, i.e., high catch rates occurred in the low temperature waters. Thus, during the months January and April, P. semisulcatus preferred waters with high temperature, usually the offshore and southern areas, while M. affinis and P. stylifera preferred waters with low temperature, usually inshore and northern areas. The relationships between the catch rate of P. semisulcatus and salinity were not so clear. Results indicated that although salinity was one of the factors affecting the distribution of P. semisulcatus, it was not the principal factor, and impacts from other variables, such as temperature, might overshadow the correlation between the catch rates of P. semisulcatus and salinity. The relationship between shrimp catch rates and dissolved oxygen (DO) also showed mixed results. The catch rates of M. affinis increased with a decrease of surface DO in November 2013, but decreased with lower bottom DO in December. These results indicated that DO might be a factor affecting distributions of the shrimp; however; the true correlation between catch rate and DO might be easily overshadowed by other environmental variables. Catch rates of P. semisulcatus did not show any relationship with depth. P. semisulcatus is a migratory species and widely distributed in Kuwait's waters.During the shrimp season from July through December, P. semisulcatus occurs in almost all areas in Kuwait's waters irrespective of water depth. The catch rates of M. affinis and P. stylifera, however, showed clear relationships with depth. Both species had significantly higher catch rates in shallower waters, indicative of their restricted distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kuwait" title="Kuwait">Kuwait</a>, <a href="https://publications.waset.org/abstracts/search?q=Penaeus%20semisulcatus" title=" Penaeus semisulcatus"> Penaeus semisulcatus</a>, <a href="https://publications.waset.org/abstracts/search?q=Metapenaeus%20affinis" title=" Metapenaeus affinis"> Metapenaeus affinis</a>, <a href="https://publications.waset.org/abstracts/search?q=Parapenaeopsis%20stylifera" title=" Parapenaeopsis stylifera"> Parapenaeopsis stylifera</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabian%20gulf" title=" Arabian gulf"> Arabian gulf</a> </p> <a href="https://publications.waset.org/abstracts/36059/relationship-between-monthly-shrimp-catch-rates-and-the-oceanography-related-variables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36059.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">490</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">59</span> The Effect of Using Levels of Red Tiger Shrimp Meal in Starter Broiler Diet upon Growth Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20I.A.%20Al-Neemi">Mohammed I.A.

A total 300 broiler chicks (Ross-308) were randomly assigned in treatments dietary contained three different levels of RTSM (0.00, 4.16 and 8.32 %) in experimental diet with a completely randomized design (CRD). Each treatment included four replicates (floor pens) and 25 broilers in each replication (Pen). Therefore, floor space for each boilers was 900 cm2. Initially, the broilers where exposed to a continues lighting of 23:30 hours and dark period of 30 minutes in each 24 hours. Feed and water were supplied ad libitum to the broilers throughout the experimental period (1-21 days). The results of this study indicated that body weight (B.W.), body weight gain (B.W.G), conversion ratio of feed, protein and energy (F.CR, P.C.R and E.C.R) were significantly (p ≤ 0.05) decreased by complete substituting (RTSM) for animal protein concentration (third treatment). Mortality percentage significantly (p ≤ 0.05) increased for third dietary treatment. No significant differences were found for feed, protein and energy intake among treatments during the experimental period (three weeks). In conclusion, (RTSM) could be included to 4.16% in the broiler starter diet or substitute the protein Red Tiger shrimp as alternative of protein animal protein concentrate as much as 50%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=red%20tiger%20shrimp" title="red tiger shrimp">red tiger shrimp</a>, <a href="https://publications.waset.org/abstracts/search?q=broiler" title=" broiler"> broiler</a>, <a href="https://publications.waset.org/abstracts/search?q=starter%20diet" title=" starter diet"> starter diet</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20performance" title=" growth performance"> growth performance</a>, <a href="https://publications.waset.org/abstracts/search?q=animal%20protein%20concentrate" title=" animal protein concentrate"> animal protein concentrate</a> </p> <a href="https://publications.waset.org/abstracts/19177/the-effect-of-using-levels-of-red-tiger-shrimp-meal-in-starter-broiler-diet-upon-growth-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19177.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">567</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">58</span> Cost Effective and Efficient Feeding: A Way Forward for Sustainable and Profitable Aquaculture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawan%20Kumar%20Sharma">Pawan Kumar Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Stephan%20Sampath%20Kumar"> J.

Apparently, excess dietary protein is undesirable, as it not only enhances the production cost but also leads to water quality deterioration. A field survey was conducted with aqua farmers of Kerala, India, a leading state in coastal aquaculture, to assess the role of protein component in feed that can be efficiently and effectively managed for sustainable aquaculture. The study showed an average feed amount of 13.55 ± 2.16 tonnes per hectare was being used by the farmers of Kerala. The average feed cost percentage of Rs. 57.76 ± 13.46 /kg was invested for an average protein level of 36.26 % ± 0.082 in the feed and Rs.78.95 ± 3.086 per kilogram of feed was being paid by the farmers. Study revealed that replacement of fish meal and fish oil within shrimp aquafeeds with alternative protein, and lipid sources can only be achieved if changes are made in the basic shrimp culturing practices, such as closed farming system through water recycling or zero-water exchange, and by maximizing in-situ, floc and natural food production within the culture system. The upshot of such production systems is that imports of high-quality feed ingredients and aqua feeds can eventually be eliminated, and the utilization of locally available feed ingredients from agricultural by-products can be greatly improved and maximized. The promotion of closed shrimp production systems would also greatly reduce water use and increase shrimp production per unit area but would necessitate the continuous provision of electricity for aeration during production. Alternative energy sources such as solar power might be used, and resource poor farming communities should also explore wind energy for use. The study concluded that farm made feed and closed farming systems are essential for the sustainability and profitability of the aquaculture industry. <p class="card-text"><strong>Keywords:</strong>
