The effect of artifical substrates on nursery of Macrorachium rosenbergii (De Man) in net cages

Abstract

Macrorachium rosenbergii postlarvae measuring 1.27 to 0.04 cm and 0.007 g were reared in net cages at the rate of 500/m2 (300/cage) to determine the effects of 0, 1 and 2 substrate level on the survival and growth.
