Abstract: Chinese mitten hand crab Eriocheir sinensis larvae and juveniles were reared in a tank made by authors under various light colors including blue（446-493 nm），green（502-579 nm），yellow（586-600 nm），red （620-644 nm）and white（440-637 nm）at water temperature of 17.3-19.1℃to investigate effects of color light on aggregation of the larvae and food intake of the juveniles.The results showed that the larvae from zoeaⅡto zoea Ⅴand megalopa had very significantly higher aggregation under blue light than under the other color light（P＜0.01）.The maximal megalopa（1097 individuals）in number were captured by a 1 L collector under blue light in an outdoor earthen pond，significantly higher than those under the green light（629 individuals）（P＜0.05），and very significantly higher than under white light（253 individuals），red light（121 individuals）and yellow light（35 individuals）（P＜0.01）.Observation of feeding activity revealed that there was no significant difference in food intake in the crab juveniles among all color light groups（P＞0.05），even though higher in day time than in night time （P＞0.05）.
