Abstract

Larval rearing, swimming, feeding and biting behavior of African catfish, Clarias gariepinus were studied under five different light Intensities (0, 0.1, 1, 10 and 100 lux). The study was conducted for 20 days, from 0 dAH until 20 dAH. In addition, the effects of light Intensity on survival rate and growth rate were also evaluated. African catfish larvae had the highest survival under dim light condition and highest growth under dark condition. Beside, Swimming activity and Ingestion rate of brine shrimp (Artemia naupli) also highest under dim light condition. Beside, for biting behavior experiment, African catfish were found that had the lowest number of biting activity under the dim light condition. Therefore, from these results can be recommended that African catfish larvae can be cultured under dim light condition to obtain higher Survival rate and lower cannibalism.
