【摘要】 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更多还原

【Abstract】 The effects of body size,food density and its quality on assimilation efficiency of pacific oyster ( Crassostrea gigas ) were studied under artificial conditions in laboratory.The experimental results show that the filtration and ingestion rates of pacific oyster increased with its body size,which tallied with power function.The assimilation efficiency of pacific oyster was not significantly correlated with its body size,but correlated positively with the organic matter content of food and negatively with food density.更多还原
