Studies on the effect of different food items on the survival of hatchlings of Clarias anguillaris

Abstract

Hatchlings of clarias anguillaris produced at Nnamdi Azikiwe University, Awka, Nigeria, were cultured in plastic aquaria set up in flow through system and observed for 30 days. The effect of different food items such as artemia, moina, zooplankton (mixture of artemia and moina), mixture of zooplankton and artificially compounded feeds on the survival of hatchlings were monitored. It was observed that the hatchlings on single diet could not survival beyond the 19th day of life. The individuals, were all the live foods plus the compounded feed were given, gave 90% survival after 30 days observation period. It is therefore recommended that live food in a mixture of compounded feed be fed to clarias anguillaris for high percentage survival to be achieved.


Key words: clarias anguillaris, Hatchlings, survival
