Abstract

A factorial experiment containing various protein and energy levels of diets was conducted for 60 days to determine the response of Indian White Shrimp, Penaeus indicus, juvenile whit mean weight of 3.22±0.04 g. Nine diets containing three levels of protein (35, 40 and 45%) and three levels of energy (350, 380 and 410 kcal/100g) were formulated and prepared in this trial. So this study was conducted with 9 treatments and triplicate random groups of 20 shrimps per each 300-liter tanks.
 Each tank was filled with 200 lit, water and exchanged 50 percent every day. The shrimp were fed their respective diets as a situation with the feed divided into three parts of feeding at 08:00, 14:00 and 20:00 h daily.
 In this study, D8 (40:410) diet with P/E ratio of 95.7mgp/kcal represent the notable performances for P. indicus. Furthermore, the present study showed that at constant protein levels, growth performances improved with increase in energy levels. The results of study also indicated at constant energy levels, weight gain, SGR, FCR and yield improved with increase in P/E ratio, but PER and NPU demonstrated a negative relationship between protein levels of 35 to 45.
The proximate analysis and amino acid profiles of shrimp carcass did not show significant difference among the different diets.
