Abstract: There are three different biological bait feeding modes to feed the Chinese mitten crab stage larvae, which are the individual feeding rotifers, rotifers and Artemia mixed feeding and the individual feeding Artemia. Parameters such as megalopae of metamorphosis to metamorphosis rate, metamorphosis megalopa of Megalopae survival rate and survival postlarvae (Megalopae and juvenile) weight after the experiment were used to discuss the investment and feeding modes of Chinese mitten crab. The results showed that among three biological bait feeding modes, the rates of zoea survival and metamorphosis at 96 h fed with the highest Artemia group were 33.33%±2.31% and 86.2%±7.2%, respectively. The average weights were not significantly different among the survival megalopa of the three different biological bait feeding modes. The average weight of survival of I larval was between (12.10±0.98)mg and (13.16±1.10)mg (P <0.05). The average length of survival megalopa fed with the Artemia was the best.
