大李家湾养殖水域浮游动物数量分布

1997年4月至1998年4月对大李家湾养殖水域进行了综合调查。结果表明，大李家湾共鉴定出浮游动物52种，隶属于5门、5纲、15目、33科40属。浮游动物生物量在养殖区内、外月际变化趋势相同，生物量差别不大。1月份生物量最高，11月份最低。在个体丰度上，小型浮游桡足类所占比例较大。同时，分析了浮游动物的分布与环境因素之间的关系。

Distribution of zooplankton in mariculture areas of Dalijia Bay

The survey of the mariculture area in Dalijia Bay was carried out from April 1997 to May 1998. The result of zooplankton was reported in this paper. As a result of analysis, 52 species of zooplankton were identified. They fall into 5 phylums, 5 classes, 15 order, 33 families, and 40 genera respectively. The biomass of zooplankton inside and outside the mariculture area have the same trend of distribution which shows a maximum in January and a minimum in November. As far as individual abundance, small copepoda have larger proportion.At the same time, the relationship between zooplankton distribution and environmental factor was discussed.
