Effects of varied types of live feeds and pelleted feeds on the bioenergetics and reproductive performances were studied under laboratory conditions. The highest feeding rate of 279.4 J/g live fish/day was observed in test fishes feed with Moina. Fish fed with pelleted feed exhibited the lowest feeding rate of 104.4 J/g live fish/day. But the absorption efficiency showed the opposite trend. The fish fed with pelleted feed showed the highest absorption efficiency 36% whereas the fish fed with Brachionus plicatilis exhibited the lowest absorption efficiency of 28%. The brood stock maintenance and larval growth were closely observed. The larvae grew like adult after 25th day of hatching. The mortality noticed during 2nd and 7th day of hatching was overcome by feeding the larvae with nutrient rich live feed. The sexually mature females and males were injected with 50 µg of GnRHa (gonadotrophin releasing hormone analogue) encapsulated in a biodegradable copolymer of fatty acid dimer and sebacic acid p (FAD-SA) of a 25:75 molar ratio. After fifteen days all treated females commenced spawning. Similar treatment induced a two-fold increase in sperm volume in male. Conclusion of the present study indicated that the laboratory scale production of marine clown fish, Amphiprion sebae can be successfully carried out using live feed than the pellet feeds which express better feeding rate, spawning and development.
