This study has been conducted from March to April 2017 in the Laboratory of Aquaculture, Aquaculture study Program, Faculty of Agriculture, University of Sriwijaya. This research was arranged according to completely randomized design (CRD) with 5 treatment levels and 3 replications. The treatment levels consisted of P1 (0 % industrial soy sauce liquid waste + 100 % Zarrouk medium), P2 (25 % industrial soy sauce liquid waste + 75 % Zarrouk medium), P3 (50 % industrial soy sauce liquid waste + 50 % Zarrouk medium), P4 (75 % industrial soy sauce liquid waste + 25 % Zarrouk medium), P5 (100 % industrial soy sauce liquid waste + 0 % Zarrouk medium). The parameters observed during the study were population density and the maximum specific growth rate. The result of this study showed that the treatment P2 gave the best in maximum density (60.6 g.L-1 ) and specific growth rate (14.66%. day-1).
