An artificial diet for larval rabbitfish Siganus guttatus Bloch.
Share
Abstract
A 21-day feeding trial was conducted to determine growth, survival and metamorphosis of larval rabbitfish (Siganus guttatus ) fed artificial diets containing approximately 40, 45, 50 and 55% crude protein. Artemia nauplii served as the control feed. Larvae performed equally well on all artificial diets with specific growth rate, % metamorphosis and % survival of 7.80-8.35, 95.2-97.9% and 59.9-70.3%, respectively. In contrast, Artemia -fed larvae exhibited poor growth (5.03) and low survival (51%) possibly due to inadequate feeding level or poor nutritional quality of Artemia . Hence, a diet with 40% protein and estimated energy content of 3,971 kcal kg super(-1) may be used with satisfactory results during hatchery production of rabbitfish.

Processing of feedstuffs and aquafeeds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2002)This 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. -
Management of feeding aquaculture species
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2002)This 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. -
