Abstract

Feed are one of the factors which is very influence on tilapia growth. The development of tilapia cultured was affected on waste increase in the waters. Biofloc technology was one alternative system to resolve the problem of waters waste. This study was aimed to analyzed growth and survival rate of tilapia with different feeding rate (FR). Experimental design was used completely randomized design (CRD). The treatments tested were (A) 7% FR, (B) 5% FR, (C) 3% FR with three treatments and three replications. The study was conducted using tilapia juvenile 5 cm with average weight 2 gram which was cultivated in 3,140 m3 fiber pond. The observed parameters include absolute growth, growth rate, survival rate, feed conversion rate. The allocation of different FR of biofloc system significantly different on growth and FCR of tilapia, but was not significantly different on survival rate of fish. Treatment with 7% FR was giving the best results with absolute growth was 8,83 gram, day growth rate was 0,221 gram/day, survival rate with percentage of 89,67%, and FCR was 1,5. The optimal absolute body weight of this biofloc system was in 7,3% FR. Keywords : Biofloc, tilapia, feeding rate, growth and the survival rate
