摘要

Abstract

Hybrid tilapia were reared at densities of 1

5 or 10 fish per tank for four weeks. Mortality was 0 at 1 and 10 fish per tank

but was 25% at 5 fish per tank. Specific growth rate was highest at 1 fish per tank

and lowest at 5 fish per tank. The lower growth rate at the intermediate stocking density was associated with reduced feed efficiency

but there was no reduction in feed intake or digestibility. The results suggested increased metabolic cost caused by aggressive behaviour at intermediate stocking density

which can be suppressed by a further increase in density.
