本文对大港湾浮游动物调查的结果进行了研究分析，共记录各类浮游动物７９种，划分有三个生态类群，以沿岸低盐暖水性类群和广盐暖水性类群为主体，体现亚热带性质的群落结构特点，总生物量和总个体数量均较高，分布趋势基本一致，南部水域高于北部水域，外侧水域高于内侧水域，高生物量区分布在东南侧。据大港湾浮游动物的多样性指数和丰富度等指标的分析结果。认为：大港湾未受污染，浮游动物种类丰富，多样性好，发展网箱养殖前景

Survey Report of Zooplankton in Dagang Bay

According to the result of survey on zooplankton in Dagang Bay, the were 79 species identified, which were divided into three ecological communities. Among them, ner-itic low salinity warm community and euryhaline warm community were dominant, which embodied the subtropical characteristic of community structure. Both the biomass and individual number of zooplankton were higher and their distribution trend was similar, as the south region was higher than the north region, the outside region was higher than the inside region. Based on the ecological characteristics, such as abundance indes and diversity indes, the result showed that the water of Dagang Bay hasn't polluted, the species were abundant, diversity and the future of cage culture industry were good.It also compared the species composition, biomass and community structure characteristics in Dagang Bay with those in Meizhou Bay, they were all higher than those in Meizhou Bay. And they had 50 species in common, similarity indes Cc was 50% .
