在室内实验条件下 ,研究了体重、饵料密度和质量对太平洋牡蛎同化率的影响 .结果表明 ,太平洋牡蛎的滤水率、摄食率随个体的增大而增加 ,并且都符合幂函数模式 :FR (IR) =aWb.太平洋牡蛎同化率与其个体大小的关系不明显 .饵料丰度和质量是影响太平洋牡蛎同化率的重要因素 .随食物中有机物含量 (POM /TPM )的增加 ,太平洋牡蛎的同化率也增加 ,随饵料密度的增加而降低 The effects of body weight, diet density and mass on the assimilation rate of Pacific oyster were studied under laboratory conditions.The results showed that the filtration rate and feeding rate of Pacific oyster increased with the increase of individuals, and all fit the power function model: FR (IR) = aWb. There was no significant relationship between the assimilation rate and the individual size of Pacific oyster.Individual abundance and quality were the important factors affecting the assimilation rate of Pacific oyster.As the content of organic matter (POM / TPM) increased, the assimilation of Pacific oyster The rate also increased, decreasing with increasing feed density
