In the present study, the effects of different dietary regimes on digestive system in stinging catfish, Heteropneustes fossilis (Bloch) larvae were investigated. Seven different dietary regimes (DR), varying in food type (Artemia nauplii, zooplankton or microdiet) and their combinations, were evaluated in triplicate. Effect of different dietary regime on the histology of the digestive system, was observed that weaning had effect on the development of the digestive organ such as stomach, liver and pancreas in terms of the size of organs and lipid accumulation in liver and gastric glands number in stomach except intestine where no change was observed. However, at the end of study (22 dph), no differences were observed in the development of digestive system among different dietary regime regardless of the weaning strategies investigated. In conclusion, stinging catfish larvae can be rear with artemia for a few days followed by zooplankton, and may be weaned onto microdiets after a short period of co-feeding which gave better survival. This information would be very helpful to improve the larval rearing techniques for this important candidate catfish species in the Asian countries.
