Growth and survival of Pacu Piaractus brachypomus (Cuvier 1818) fed on crude protein from shrimp waste meal

Abstract

The objective this study was to find out the protein requirement from Shrimp waste meal for superior growth and survival of juveniles of Pacu under laboratory conditions. Three experimental diets were prepared from Shrimp waste maintaining the crude protein levels at 25, 30 and 35% (treatment T1, T2 and T3). Within an experimental period of 90 days, the control group of fishes attended an average weight of 9.81 ± 0.34g with an intermittent growth of 6.27 ± 0.31g and 8.00 ± 0.05g at the end of 30 days and 60 days. Pacu juveniles in T2 fed with 30% crude protein showed better increment in weight of 10.21 ± 0.46g, 23.00 ± 0.43g and 33.22 ± 0.60g at the end of 30 days, 60 days and 90 days respectively along with increment in total length.
