Status Trofik Media Budidaya Ikan Nila (Oreochromis niloticus) Sistem Bioflok

Abstract

This experiment aimed to analyze the trophic status, floc volume, survival and growth rate of Nile Tilapia reared within biofloc system. A completely randomized design (CRD) with four treatments and three replicates was applied. The treatments were the difference in biomass stocking density. i.e; P1 (5 kg/m3) ; P2 (10 kg/m3); P3 (15 kg/m3) and P4 (20 kg/m3). Result showed that the survival rate of fish and floc volume have no significant difference among treatments. But, the growth of fish and the trophic status of culture media significantly differed among treatments. The highest growth rate was achived by P1 (5 kg/m3) and the lowest one was by P4 (20 kg/m3). Water quality parameters were recorded in the range of tolerable values for Tilapia raising during the treatments.
