An experiment to evaluate the effect of replacing fish feed was conducted to evaluate the growth performance of Heteroclarias in circular tanks each having a capacity of fifty litres of water. Fishes were divided into three groups in triplicates, with 10 fishes per tank. The fingerlings stocked were of the same size and length. Fishes in tank A were fed with laboratory prepared Soya bean and corn meal feed, while B had already manufactured feed (Coppens) and C already manufactured feed (Aquamass) was used. The fingerlings were fed 4% of their body weight twice daily, from 6.00 to 8.00am and from 6.00 to 8.00pm. Growth performances were monitored weekly for eight weeks. The results showed that treatment A (laboratory prepared feed) had the best growth performance with a mean weight (23.3±0.02 g) and length (20.00 mm) gain which exceeds that of treatment B which had a mean of 10.5±0.01 g and length of (19.3 mm). There was a significant difference (p>0.05) between growth rate and different feeds.
