Abstract

Nile tilapia(Oreochromis niloticus) fingerlings (average weight and length: 20.20 ± 0.20 g, 10 ±0.25 cm)cultivated at reusing water from systems with biofloc technology (BFT) under three treatments: T1: Control, T2: tilapia cultured in reused water biofloc (RW) with adding carbohydrate and T3: tilapia cultured in reused water biofloc (RW) without adding carbohydrate. Nine rectangular tanks (66 x 47 x 44 cm, 75L) were used with stocking densities (400 Fish/m3) for 60 days to investigate fish growth performance, feed utilization, body composition, survival, water quality and also economic evaluation was done. Fish were fed a commercial diet containing 30% crude protein. Growth performance of tilapia was recorded biweekly. Water temperature, dissolved oxygen and pH, were recorded daily, while NO2–, NO3–N; total hardness, carbonate hardness and total suspended solids were recorded biweekly. The body composition of the whole fish was determined at the end of the experiment. Results showed that the best water quality parameters, finial body weight, weight gain, daily weight gain, specific growth rate, final biomass, net yield, PER, FCR, FE, feed intake and economic evaluation were significantly(P<0.05) higher in T2 andT3 than T1. Survival rate was greater than 98% in all treatments, with no significant difference between them (P>0.05). The present study recommended rearing Nile tilapia in reusing water from systems with biofloc technology (BFT) without adding carbon source for best growth performance and prolonged the useful life, quality of water and reduced overall water consumption.
