摘　　要：实验室内用静水实验方法研究西施舌稚贝的摄食率与单胞藻投饵量、摄食时间的关系,结果表明单胞藻投饵量在适宜的范围之内,随着投饵量的增加,摄食率也随之增加,而超过一定范围时,摄食率有所下降,西施舌稚贝的摄食率在投喂饵料2 h后逐步下降.In order to reveal the relationships among the clam ingestion, quantity of microalgae and the time of feeding, the experiments were carried out within static systems in laboratory. The results obtained showed that the ingestion rate of juveniles of Coelomactra antiquata increased rapidly with the increase of the quantity of microalgae when the quantity of microalgae was appropriate, but decreased when the quantity of microalgae was exceeded. After around 2 h of feeding, the ingestion rate declined gradually.
