Abstract：The carrying capacities of Manila clam Ruditapes philippinarum in Jiaozhou Bay aquaculture areas were estimated by an ecosystem model established by actual determination via concentration of phyto-plankton and primary production ,and food budgets .The results showed that the maximal carrying capaci-ty of the clam was observed in various sizes of the clam in winter (January or March) and the minimal in September .The average carrying capacity in the aquaculture areas was shown to be 603 ind ./m2 in the clam with shell length of 2-2 .6 cm ,441 ind ./m2 in the clam with shell length of 2 .6-3 .3 cm ,and 362 ind ./m2 in the clam with shell length of 3 .3 -4 cm ,indicating that the stocking density of the clam was saturated in Jiaozhou Bay w here the appropriate reduction in density w as necessary to maintain the maximal yield ,high clam quality and low seeding cost .It is recommended that the stocking density of the clam be 718 ind ./m2 in Hongdao East zone ,693 ind ./m2 in Hongdao South zone ,557 ind ./m2 in Hongdao West zone ,805 ind ./m2 in Jiaozhou zone ,and 654 ind ./m2 in Huangdao zone ,with the average stocking density of 690 ind ./m2 .
