摘　　要：采用肠含物分析和摄食实验相结合的方法,对厦门港常见浮游动物———球型侧腕水母(Pleurobrachiaglo bosa)的食物组成、摄食行为、摄食强度进行研究.并根据台湾海峡、厦门港球型侧腕水母的生物量,估算其种群摄食强度.Studies on the feeding of ctenophore Pleurobrachia globosa from Xiamen Harbour were undertaken through gut content analysis and feeding experiment, with main resuslts as follows: 1) The principal food items of P. globosa were copepod, cirriped nauplii, brachyuran zoea, macruran larvae, amphipod with different selectivity; 2) Linear relation was found between feeding rate and prey density with the food level from 440 to 1750 prey·L-1: y=76.533 7+0.202 4 x; 3) The population feeding ration in Xiamen Harbour and in Taiwan Strait was estimated from gut content and feeding experiment.
