PROTEIN REQUIREMENTS OF GIFT TILAPIA FINGERLINGS PROTEIN REQUIREMENTS OF GIFT TILAPIA FINGERLINGS REARED IN SEAWATER

Abstract

GIFT tilapia fingerlings bio growth experiment was carried out in seawater. Seven diets were fed to tilapia fingerlings with different crude protein from 15 - 45 %. The mean weight gain of GIFT tilapia fingerlings reared in seawater showed highly significant positive correlation with different inclusion level of crude protein in the experimental diet. The mean growth value of GIFT tilapia fingerlings reared in seawater fed with different experimental diets showed significance differences in C/T2 (p<0.01), T2/T5 (p<0.05) and T6/T7 (p<0.01). GIFT tilapia fingerlings reared in seawater showed better growth (0.22 g / day) diet containing 20 % crude protein than other experimental diets. The present investigation showed that GIFT tilapia fingerlings reared in seawater require 20% crude protein than other experimental diets.
