摘　　要：文章采用方建光模型,通过对广东省南澳县深澳湾养殖环境的水温、叶绿素a、初级生产力和非养殖滤食性动物生物量的调查,结合室内测定的不同规格壳长的太平洋牡蛎(Crassostrea gigas)的滤水率,并参照非养殖滤食性动物相应的滤水率,对深澳湾各月份不同规格太平洋牡蛎养殖容量进行估算。研究发现,深澳湾各规格的太平洋牡蛎最大养殖容量出现在1月份和2月份,最小养殖容量出现在5月份。各规格的太平洋牡蛎年平均养殖容量分别为:壳长3.5～5.0 cm的太平洋牡蛎年平均养殖容量为27 ind/m2,壳长5.5～7.0 cm的太平洋牡蛎年平均养殖容量为16 ind/m2,壳长7.5～9.0 cm的太平洋牡蛎年平均养殖容量为17 ind/m2,壳长9.5～11.0 cm的太平洋牡蛎年平均养殖容量为16 ind/m2。This paper uses Fang jianguang model to estimate the carrying capacity of Crassostrea gigas with various shell length in the Shen＇ao Bay of Nanao County,Guangdong Province,based on the investigation of water temperature,chlorophyll-a,primary productivity and biomass of non-farmed filter feeders in the Shen＇ao Bay,and the detection of filtration rate of C.gigas with various shell length by reference to the filtration rate of non-farmed filter feeders.The result showed that the largest carrying capacity for C.gigas appeared in January and February,and the smallest carrying capacity appeared in May,and the annual average carrying capacities for C.gigas with the shell length of 3.5-5.0,5.5-7.0,7.5-9.0 and 9.5-11.0 cm were 27,16,17 and 16 ind/m2,respectively.
