Effects of high stocking density on survival and growth of Sabaki tilapia Oreochromis spilurus

Abstract

This study's main objective was to estimate the survival rate and growth performance of grow-out Sabaki tilapia (Oreochromis spilurus, Günther, 1894) at different high stocking density levels: 50, 100, 150, 200 and 250 fish per m3. The experiments were conducted in triplicate and monitored for survival rate and growth performance for an experimental period of 16 weeks. Results indicated that the survival rate was significantly different in higher stocking density groups. The growth performance was not significantly different in each group. Overall, the results indicate that the Sabaki tilapia farming is feasible in high stocking density conditions.
