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

Abstract

In this stud y, effects of com mercial extruder diet (CED), commercial flak es (CF), Daphnia magna (DM) and 50 % commercial flakes + 50 % daphnia (CFD) on feed conversion r atio, specific growth rate and sur vival rate of ang el fish (average weight 0,73±0,02 g) ( Pterophyllum scalare Lictenstein, 1823) were investigat ed. 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 f ed with addition live food to co mmercial flakes (CF) containing low protein showed parallel gro wth to fish fed with commercial extruder diet contain high protein (CED)
