Abstract：Three tracking surveys were conducted in 2013 after the releasing of Chinese shrime Fenneropenaeus chinensis to the nature waters of Wuleidao Bay .The results were compared to find out the releasing effect of different sizes of juveniles on its stock in Wuleidao Bay .It showed that the releasing juveniles strongly enhanced the recruitment of the nature stock due to the obviously increment of biomass in the bay of Wuleidao .The phase survival rate and contribution rate of larger Chinese shrimp were 2—3 times and 2—4 times higher than the smaller ones ,respectively .Before the middle of August ,there were significant differences in body length between larger and smaller shrimp .In late August ,released smaller ones had the size close to larger ones ,both showed basically synchronous growth .However ,there was differences in somatic features between larger and smaller ones . The larger shrimps were superior to smaller ones in condition factors .
