Abstract: The wild collected in May 2005 and farmed juvenile yesso scallop Patinopecten yessoensis were cultured in rafts at Guanglu Island sea in Dalian coast from November 2005 to March 2007. It was found that the wild juveniles （7 month old） had an average shell length of 15.38 mm, shell height 16.22 mm, shell width 3.72 mm and wet body weight 0. 53 g, very significantly lower than the farmed juveniles （9 month old） （ P 〈 0. 01 ） during the early cultural period （November 2005）. There were no significant differences in shell length, shell height, shell width, and wet body weight between the wild （ 15 month old） and hatchery - produced farmed juvenile （21 month old） yesso scallop in July 2006（P 〉0.05）. Until March 2007, however, the wild juveniles （23 month old） had an average shell length of 78.49 mm, shell height 80.71 mm, shell width 22.05 mm and wet body weight 65.12 g, higher than the farmed juveniles （25 month old） . During the whole cultural period, there was very significantly higher daily growth performance （0. 1310 mm/d in shell length, 0. 1339 mm/d in shell height, 0. 0380 mm/d shell width and 0. 1341 g/d in wet body weight） in the wild juveniles than that in the farmed juveniles （0. 1143 mm/d in shell length, 0. 1157 mm/d in shell height, 0. 0347 mm/d shell width and 0. 1263 g/d in wet body weight） （P 〈 0. 01 ）. The survival rates were 80.37% and 75.35% for the wild and artificial population.
