    Abstract


    The study was carried out to identify the most suitable stocking density for mouse grouper larvae (Cromileptes altivelis)from fry to fingerling stage. The larvae were reared at the densities of 10,20 and 30 individuals/l. Lower stocking densities, at 10 and 20 individuals/l weremore favorable forspecific growth rate (0.063 and 0.0625%/day), final total length (34.45 and 33.33mm)and survival rate (6.45 and 6.30%)(P<0.05). Results showed that the most appropriate density for rearing the mouse grouper from fry to fingerling stage is 20 individuals/l to optimize the growth, survival rate and economic efficiency.
