Growth performance of Pacu (Piaractus brachypomus) fed with different protein sources

Abstract

The present study was conducted to compare the performance of growth and survival of Pacu, Piaractus brachypomus fed on different experimental diets. Pacu (1.00 ± 0.02g) were fed with nine practically prepared diets for 90 days. Ground Nut Cake (GNC), Fish Meal (FM) and Cotton Seed Meal (CSM) were used at three different protein levels (20%, 25% and 30%), basal supplemented with rice bran and maize. The growth performance of P. brachypomus was found to be best when fed with diet FM25 (126.50gm) and the least with GNC20 (117.13gm). Survival rates were best in all the treatment, which showed 100% survival rate at the end of the experiment except on GNC20 and CSM20 (90%).
