Abstract

This study was undertaken to formulate diet with the replacement of animal protein using plant protein. Growth rate and survival rate was monitored in Red Tilapia, fed with commercial pellet and formulated diet. Changes in water quality parameters were recorded. Experiment conducted with nine 200L tanks each filled with freshwater with aeration system. Each tank stocked with 180 tails measured juvenile tilapia fish. Crude palm kernel meal, crude soybean meal, crude palm oil, crude glutinous rice flour, minerals and vitamins premix were used as ingredients to formulate diet. Tilapia diets were formulated with 32% dietary protein level. Commercial pellet act as diet 1 (control diet), formulated pellet as diet 2 and 50% commercial pellet plus 50% formulated pellet as diet 3. The result indicated that, Diet 2 and Diet 3 showed significant differences (p<0.05) in weight, but no significant differences (p>0.05) in length. Better in specific growth rate and protein efficiency ratio were observed when tilapia fed with Diet 3. However, feed efficiency ratio was better when tilapia fed with Diet 2. Diet 3 was observed that ammonia concentration is the lowest among 3 Diets.
