This study evaluated the effects of dietary fermented tuna by‐product meal (FTBM) in juvenile olive flounder, Paralichthys olivaceus. Five diets were formulated to replace fishmeal (FM) with FTBM at 0% (FTBM0), 12.5% (FTBM12.5), 25.0% (FTBM25), 37.5% (FTBM37.5), or 50% (FTBM50). After 8 wk, weight gain, specific growth rate, and feed efficiency of fish fed FTBM0 and FTBM12.5 diets were significantly higher than fish fed the other diets (P < 0.05). Also, mean cumulative survival rates (%) of fish fed the FTBM0 and FTBM12.5 diets were significantly higher than those fed FTBM50 diet at Day 9 postchallenge with Edwardsiella tarda (P < 0.05). Protein efficiency ratio of fish fed FTBM0 and FTBM12.5 diets was significantly higher (P < 0.05) than fish fed diets FTBM37.5 and FTBM50. Broken‐line regression analysis of weight gain showed an optimal FM replacement level of 10.65% with FTBM. Therefore, the optimal dietary inclusion of FTBM in juvenile olive flounder diets could be greater than 10.65% but less than 12.5% without any adverse physiological effects on fish health.

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.
