The performances of fish culture were evaluated in the integrated recirculating aquaculture system consisting of a double drain type rearing tank (), a sedimentation tank, a floating bead filter, a foam separator and a rotating biological contactor. A system was stocked with nile tilapia at an initial rearing densities of (A), (B) and (C) oyer 30 days. Feed coefficient was 1.62, 1,79 and 1.80 and average daily growth rate was , 0.u5% and , respectively. The level of TAN was maintained below for of initial rearing density and for . The dissolved oxygen level () was not optimum but should not be inhibitory to fish growth. The total suspended solid was completely removed during overall experimental period. |
