摘　　要：This paper studied the effects of different kind and density of baits and different starvation duration on Charybdis japonica larvae. The results showed that the preferable baits of zoaea-1 were Chaetoceros sp. and Isochrysis galbana ,and their proper feeding density were 20×10 4 cell·ml -1 .The preferable bait of the larvae after zoaea-1 was Artemia salina nauplius, and its proper feeding density for zoaea-2 and zoaea-3 was 2～3 ind·ml -1 .The point of no-return for zoaea-1 of Charybdis japonica was about 66 hours. 18 hours starvation did not affect the growth of the larvae, but their livability would be decreased, and their metamorphism would be suspended along with the starvation duration.This paper studied the effects of different kind and density of baits and different starvation duration on Charybdis japonica larvae.
