摘要
1996～ 1998年对黄海北部对虾放流区进行了调查 ,共获得浮游动物 38种 ,优势种为小拟哲水蚤、克氏纺锤水蚤、大同长腹剑水蚤、尖尾海萤。浮游动物生物量 3年总的趋势是逐年增加 ,总平均值为 86 8 8mg/m3,比 1991～ 1992年有所增加。总体分析后认为
Distribution, species, and number of the zooplankton were investigated in the coast of Northern Yellow Sea where shrimp were stocked with from 1996 to 1998. Thirty-eight species of zooplankton were found, of which \%Paracalanus parvus, Acartia chausi, Oithona, Oypridina acuminata\% were of the dominant species. Average annual zooplankton biomass of 868.8 mg/m\+3, higher than that in between 1991 to 1992. Decline in recaptuer rate of Chinese shrimp may be attributed to other factors instead of decrease in zooplankton biomass.
