Use of soybean meal and rice bran in formulated diets for the grouper Epinephelus coioides
MetadataShow full item record
Two 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.

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.

Three kinds of non-fish meal diets and a control diet containing 50% fish meal were processed. In the non-fish meal diets, the fish meal was replaced with commercially available plant or animal materials and supplemented with taurine and other ingredients for maintaining palatability. These diets were fed to one year old yellowtail (body weight: 753±96 g) in net cages. No significant differences in growth, daily weight gain, daily feed rate, feed conversion ratio and protein efficiency ratio were observed among fish given the diets. Non-fish meal diets were processed in a factory and their biological characteristics were studied such as uptake, stomach evacuation rate, and disease resistance. In addition, the diet palatability of each substitute protein source for fish was examined and ingredients that enhanced palatability of the non-fish meal diets were identified. Non-fish meal diets have the potential to support the growth of one year old yellowtail.

Development and use of alternative ingredients or fish meal substitutes in aquaculture feed formulation: Proceedings of the ASEAN Regional Technical Consultation on Development and Use of Alternative Dietary Ingredients or Fish Meal Substitutes in Aquaculture Feed Formulation MR Catacutan, RM Coloso & BO Acosta (Eds.) - 2015 - Aquaculture Department, Southeast Asian Fisheries Development CenterRecognizing the need for a concerted effort to follow-up on this priority issue of the ASEAN on aquaculture feed development and utilization. SEAFDEC (Aquaculture Department and Secretariat) and the Government of Myanmar organized the 'Regional Technical Consultation (RTC) on development and Use of Alternative Dietary Ingredients or Fish Meal Substitutes in Aquaculture Feed Formulation'. The meeting was convened with the main purpose of providing a forum for charting the regional priorities and future directions on feed development, particularly on the use of alternative feed ingredients or protein substitutes. The specific objectives were to: (i) review the ASEAN-SEAFDEC member country status, constraints associated with developing alternative dietary ingredients for aquaculture feed; (ii) identify specific advances being made in the region with respect to the development of alternative aquaculture feed ingredients; and (iii) define approaches or initiatives supporting catch reduction of low-value/trash fish; (iv) formulate relevant policy recommendations (regional and country-specific) for effective development and utilization of aquaculture feeds; and (v) enhance cooperation among member countries and relevant stakeholders on initiatives that support sustainable aquaculture practices, particularly on feeds. This publication presents the outputs of the RTC. The country reports and review papers presented during the conference which are contained in this volume are cited individually.
