Development of formulated feeds for grow-out culture of grouper (Epinephelus coioides) - tank and field studies
MetadataShow full item record
The objectives of this study were to compare the performance of a Southeast Asian Fisheries Development Centre (SEAFDEC) formulated diet with a commercial feed for growout culture of grouper and to transfer technology on grouper diet developed at SEAFDEC to the industry. In the tank study, Epinephelus coioides juveniles were reared in 12 units of 150-litre tanks at 15 fish/tank with 4 replicates per treatment. Fish were fed the diets at a feeding rate of 5-6% of body weight (BW) and trash fish at 10-12% BW per day for 60 days. In the feeding trial, treatments were arranged in a randomized complete block design with size groups as block. 36 fish were stocked per size group. Formulated feeds were given twice a day for 120 days. In the tank study, the commercial feed resulted to significantly lower growth, survival and food conversion ratio (FCR) compared with the SEAFDEC diet and trash fish control. Results of the field trials at growout ponds did not show significant differences in growth performance, survival and FCR of grouper juveniles fed with the diets. Both the SEAFDEC diet and commercial feed conformed to the established protein requirement of juvenile grouper. In tank trials, the poor performance of commercial feed was attributed to the low protein content and deficiencies in essential amino acids as confirmed by analysis of the amino acid composition. Improvement in growth performance of fish given the commercial feed was achieved in field trials by increasing the dietary protein level and improving the amino acid composition to match that of the grouper juveniles.

Book chapterVR Alava - 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 CenterThis chapter teaches the reader to: differentiate the different feeding strategies in pond culture; learn feeding management methods such as stock sampling and record keeping, calculating daily feed ration, choosing appropriate feed size, and methods of applying feeds; understand the impact of feeding management on water quality and environment and on the cultured animal’s growth, survival, and feed conversion ratio; and describe the different feeding schemes used to culture fishes (milkfish, tilapia, rabbitfish, bighead carp, native catfish, sea bass, orange-spotted grouper, and mangrove red snapper; and crustaceans (tiger shrimp and mud crab). Other species for aquaculture stock enhancement (donkey’s ear abalone, seahorses, window-pane oyster) are also discussed.
Book chapterNV Golez - 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 CenterThis chapter will help the reader understand and appreciate the basic principles of processing, preparation, storage, and quality control in the preparation of aquafeeds. The material in this section is presented in sequence beginning with the processing of basic ingredients to remove antinutritional factors, followed by steps in feed preparation, from the easiest to the more complex processes, and storage. This chapter presents methods and equipment that are useful not only for feed millers, but also for extension workers and fish farmers.

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.
