Effect of Different Feed Types on Growth and Feed Conversation Ratio of Angel Fish (Pterophyllum scalare Lictenstein, 1823)

Abstract

In this study, effects of commercial extruder diet (CED), commercial flakes (CF), Daphnia magna (DM) and 50 %
commercial flakes + 50 % daphnia (CFD) on feed conversion ratio, specific growth rate and survival rate of angel fish
(average weight 0,73±0,02 g) (Pterophyllum scalare Lictenstein, 1823) were investigated. The experiment groups were fed for 60 days. According to the results of this study, the best weight gain, specific growth rate and condition factor were found on commercial extruder diet group. The worst of growth was found on commercial flakes group. However, growth of CFD group fed with addition live food to commercial flakes (CF) containing low protein showed parallel growth to fish fed with commercial extruder diet contain high protein (CED).
