A 60-day indoor growth trial was conducted to study the effect of dietary supplementation of biofloc meal with tryptophan on growth and survival of juvenile GIFT tilapia. Five isonitrogenous and isoenergetic experimental diets (32% protein) were prepared at different enrichment levels of crystalline tryptophan viz., 0.1% (T1), 0.2% (T2), 0.3% (T3), 0.4% (T4) enriched with 20% biofloc meal included diet and control diet (T0) without tryptophan and biofloc meal. A commercial diet (T5) was used to compare the experimental diets. This feeding trial was conducted in 18 numbers of 40 L plastic troughs in triplicates, utilizing GIFT tilapias weighing with an average of 2 g size. During the experimental period, water quality parameters were measured and recorded daily. Among the experimental diets highest mean body weight of GIFT tilapia were recorded in T3 (41.84±1.09 g) followed by T4 (39.01±2.37g), T1 (36.77±2.54 g) and T2 (33.37±1.05g). Hence, the present study was assessed that diet with 20% biofloc meal supplemented with 0.3% tryptophan can improve the growth and survival of GIFT tilapia without any adverse effect on the fish performance.
