Skip feeding as an alternative strategy in the production of Nile tilapia Oreochromis niloticus (Linn.) in cages in selected lakes in the Philippines
MetadataShow full item record
Many inland water bodies in the Philippines are currently used for fish cage culture. Inappropriate practices including feed management in aquaculture results not only in the degradation of water quality but also in economic losses for the fish farmers. The effect of two feeding management schemes on the production of cage-cultured Nile tilapia Oreochromis niloticus (Linn.) in Lakes Bato and Buhi in Camarines Sur Province and Laguna de Bay in Rizal Province were studied. Daily (DAILY) and skip-feeding (SKIP) schemes using the same daily ration based on standing biomass were used. Mean final weight and daily growth rate were 18% higher in DAILY compared with SKIP in Lake Bato. No significant differences in both parameters were observed in tilapia reared in the two feeding treatments in Lakes Buhi and Laguna de Bay. Condition factor, survival and final yield did not show any significant differences in both treatments in all three lakes. Significant differences in feed conversion ratios (FCR) were observed between the two treatments with SKIP having 36% lower feed conversion ratio (FCR) in Lake Bato and 41% lower FCR in Lake Buhi and Laguna de Bay compared with the DAILY treatment. The results suggest that skip feeding is an economically and ecologically viable alternative to the cage culture of Nile tilapia in cages.

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.
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.

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.
