摘要:

2008 年 3 月—2009 年 1 月调查分析流沙湾浮游动植物的生物量、叶绿素 a 含量、初级生产力、马氏珠母贝
Pinctada martensii 含壳重与鲜组织重的比值、养殖贝类和野生滤食性动物的滤水率、潮间带和潮下带底栖贝类及
吊养区附着滤食性动物现存量等,  应用营养动态模型和贝类养殖容量估算模型估算滤食性动物的总容量,  扣除野
生滤食性动物现存量,  最终确定马氏珠母贝的养殖容量。结果显示, 2 种模型估算马氏珠母贝的养殖容量分别为
19637.5t 和 20126.4t,  平均养殖容量 19881.95t。依据流沙湾马氏珠母贝的通常养殖密度(1.05×105
个·hm−2)和平均商品规格(41g·个−1)计算,  流沙湾马氏珠母贝的适养面积为 461.83hm2。

Abstract:

Nutrient Dynamic Model and Fang Jianguang’s Model were used to estimate aquaculture carrying capacity of
Pinctada martensii in the Liusha Bay. Biomass of plankton, chlorophyll a, primary production, weight ratio of whole P.  ma r t -
ensii to fresh tissue, biomass of benthic shellfish in tidal and subtidal area, biomass of fouling filtered animals in the Liusha
Bay were measured during March 2008 to January 2009. The filtered rates of cultured shellfish and wild filter animals were
measured by the Clearance Method. The aquaculture carrying capacity of P. martensii was estimated by excluding the biomass
of wild filtering shellfish from the carrying capacity of filtered animals. The results show that aquaculture carrying capacity of
P. martensii in the Liusha Bay should be 19637.5t and 20126.4t according to the results of the two models, with an average of
19881.95t. The suitable area for culturing P. martensii in the Liusha Bay
should be 461.83hm2
based on normal culture density
(1.05×105
ind·hm−2
) and average commercial size (41g·ind−1
).

Key words: Liusha Bay, Pinctada martensii, aquaculture carrying capacity
