摘　　要：笔者于2013年12月采用实验生态学方法,在室内进行不同体质量不同投饵时间、不同饵料密度对波纹巴非蛤[Paphia undulata(Born)〗滤水率的影响实验。结果表明:(1)波纹巴非蛤的滤水率(FR)随着体质量的增大而增大,单位体质量的滤水率(FR')随着其规格的增大而减小,FR'=0.330 3W-0.356 9(R2=0.996 5)。(2)分别以金藻和扁藻作为饵料,测定了8:00,14:00及20:00这3个时间点的滤水率,滤水率在8:00最大,14:00及20:00依次减小,3个时间点滤水率差异显著(P<0.05)。(3)以金藻和扁藻作为混合藻,滤水率随着藻密度的增加而增大,当浓度超过3.06×105cell·L-1,滤水率反而下降。Paphia undulata （Born, 1778） collected from Shen＇ao Bay, Shenzhen, Guangdong, China were fed thrice in the polyethylene buckets of 5 L with algal diet at different rates and different time in December 2013 to observe their filtration rates and carrying capacity by using the method for experimental ecology. P. undulata were observed to increase their filtration rates with their body weight, but their filtration rates per body weight were reduced with an increase in the body size ofP. undulata： FR＇ =0. 330 3W-0.3569（R2 =0. 996 5）. P. undulata were fed with algae Isochrysis galbana and Platymonas subcordiformis separately to observe their filtration rates at 8 am, 14 pm and 20 pm, and the filtration rates were found maximum at 8 am, followed by at 14 pm and 20 pm, and showed significant difference among these three feeding hours （P 〈 0. 05）. P. undulata were fed with the mixture of L galbana and P. subcordiformis, and their filtration rates were increased with the cell density of the mixed feed in the buckets, but decreased when the cell density exceeded 3.06 × 105cell·L-1.
