The effect of rice bran and fish meal on heteroclarias and tilapia niloticus

Abstract

A Feeding trial was conducted to assess the growth performance of Heteroclarias and Clarias gariepinus in a Polyculture with Tilapia niloticus fed twice daily, seven times a week on rice bran and fish meal containing 28% crude protein, 8% crude fat, 1.6 % crude fibre, 4.5% moisture and 6.2% ash at 3% bodyweight. The experiment lasted for a period of 12 weeks. Rice bran and Fish meal were used per feeding time for each of the species to assess their performance. The response to the feed and the species were compared. Heteroclarias performed better in terms of growth rate than Clarias gariepinus, while Polyculture of hybrid (Heteroclarias) with Tilapia niloticus performed better compared to the Polyculture of Clarias gariepinus with Tilapia.
