Evaluation of leguminous seed meals and leaf meals as plant protein sources in diets for juvenile Penaeus indicus
MetadataShow full item record
The potential of locally available legumes (white cowpea, Vigna unguiculata, and green mung-bean, Vigna radiata) and leaf meals (papaya, Carica papaya, and cassava, Manihut esculenta) in combination with defatted soybean meal as protein sources was evaluated in juvenile Penaeus indicus. The feedstuffs were included in practical diets for P. indicus, replacing 9% of the protein in the basal diet. Juvenile P. indicus (mean initial weight 0.08±0.01 g) were fed the practical diets for 61 days. Shrimp fed the control diet had the highest weight gain and specific growth rate, which did not significantly differ (p>0.05) from those of shrimp fed white cowpea meal, papaya leaf meal and cassava leaf meal. Survival of the control shrimp was significantly higher (p<0,05) than that of shrimp fed cassava and papaya leaf meals but comparable to that of shrimp fed white cowpea meal. The growth of shrimp given green mungbean meal was comparable to that of shrimp fed papaya leaf meal, however the shrimp fed mungbean meal had the lowest survival. The apparent protein digestibility (APD) of white cowpea meal (87%) was significantly higher (p<0.05) than that of the control (82%) and cassava leaf meal (77%) based diets . However, the APD of the white cowpea meal based diet was comparable to those of the papaya leaf meal and green mungbean meal based diets. Results suggest that, besides digestibility, other factors such as the amino acid balance of the diet and the amount of anti-nutritional factors may influence the growth and survival of P. indicus.

Supporting ASEAN good aquaculture practices: Utilization of alternative protein sources for aquafeed to minimize pressure on fishery resources REP Mamauag -
Fish for the People, 2016 - SEAFDEC SecretariatAquaculture industry of Southeast Asia has been expanding steadily as a result of an increasing demand of food fish in the region as well as in the global scale. Aside from its contribution to the world’s fisheries, the aquaculture industry creates employment opportunities and provides income for the region’s fish farmers, as well as produces fish which is a major component in the diets of peoples in Southeast Asia. However, the fast development of aquaculture had been viewed as threat to sustainable capture fisheries production as the widespread use of fish by-catch in aquaculture feeds results in overexploitation of the fishery resources and to certain extent degradation of the resources. Recognizing the importance and urgency of addressing such concern, the Senior Officials of the ASEAN Member States responsible for fisheries adopted in June 2011, the Plan of Action on Sustainable Fisheries for Food security for the ASEAN Region Towards 2020 which includes provision on the need to “improve the efficient use of aquatic feeds by strictly regulating the quality of manufactured feed and feed ingredients and support continued research for developing suitable alternative protein sources that will reduce dependence on fishmeal and other fish-based products.” Along with such declaration, the SEAFDEC Aquaculture Department has been enhancing its R&D activities aimed at finding alternatives to fishmeal as feed ingredients in aquaculture feed formulations.
Book chapterMR Catacutan - In OM Millamena, RM Coloso & FP Pascual (Eds.), Nutrition in Tropical Aquaculture: Essentials of fish nutrition, feeds, and feeding of tropical aquatic species, 2002 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe development of a feed that is both effective and economical for an aquaculture species in all its life stages is a continuous effort. Aquafeed development started when natural food sources in culture systems became inadequate and had to be supplemented with prepared feed. As fish stocking densities in culture increase, supplemental feeding is no longer sufficient. A complete feed that contains all the necessary nutrients in sufficient amounts to bring about good growth, survival, and reproduction is needed. Feed ingredients generally come from animal or plant sources and some are by-products of the food industry. There is no single feed ingredient or feedstuff that contains all the nutrients in adequate amounts. Thus, different feed ingredients are combined to make a feed that has the desired composition and nutrient levels. In combining various feed ingredients, it is important to know how much of each feed ingredient should be used to produce a cost-effective aquafeed. With the growth and expansion of aquaculture into a major industry, several fish species are being cultured; thus, the development of more efficient aquafeed formulations should continue. In developing cost-effective formulated diets, many important factors have to be considered. This chapter discusses these factors and the mathematical calculations in formulating a feed. It aims to enable students to formulate diets using purified and practical feed ingredients, and also to formulate effective supplemental and complete diets for aquaculture species.
Book chapterET Marasigan, SL Miag-ao & AE Serrano - In T Bagarinao (Ed.), Research Output of the Fisheries Sector Program, 2007 - Bureau of Agricultural Research, Department of AgricultureTwo diets were formulated to include 8–14% soybean meal and 9–18% rice bran, 34–40% fish meal, 4–5% mussel meal, and 7–8% Acetes shrimp meal, and 11–13% cod liver oil. Soy bean meal and rice bran were included at 4:1 ratio together to replace 12.5% and 25% of the animal protein sources in the two diets. The two diets were prepared in dry D form and moist M form. The four test diets, D12.5, M12.5, D25, and M25 diets had 40–42% protein and 4,000 kcal/g gross energy. The control diet used was a dry diet with 44% crude protein and 4,260 kcal/g, made with 30% Peruvian fish meal, 8% squid meal, 22% Acetes shrimp meal, 8% cod liver oil, 8% soybean oil, but no plant protein sources. The five diets were fed to juvenile grouper (mean weights ranging from 1.63 ± 0.47 to 2.41 ± 0.91 g) in indoor 400 L concrete tanks (10 fish per tank). After 10 weeks, growth, feed intake, feed conversion ratios (1.2–2.2), and survival (60–80%) of juvenile grouper were not significantly different between the test diets and the control. The carcass composition of the harvested grouper was not significantly different among diets. Protein utilization was best among the fish fed the test diet D12.5. This study showed that soybean meal and rice bran at 4:1 ratio can be included in formulated diets for grouper to replace 12.5% to 25% of the animal protein sources. However, the results for the test diets may also have been due to other factors - the high fish meal content, inclusion of mussel meal, and increase in cod liver oil.
