Abstract
In the present research work, an attempt was made to standardize the larval rearing technique of Ompok bimaculatus (Pabda), an endangered catfish of North-East India for sustainable conservation & diversification of aquaculture in general. Two days old yolk sack larvae were reared in the laboratory conditions for a period of 12 days and survival percentage at the end of the experimental period was recorded. The results of the study showed that it was possible to obtain a survival percentage ranging from 47% - 62 %. Further, rearing of larvae in cement tanks for a period of 30 days resulted in a survival percentage of about 90%. The results demonstrate the potential to improve larval survival by providing apt food and water quality conditions.
