于2001年9月~2002年9月对大连黑石礁海区浮游动物的生态学进行了调查研究,共鉴定出桡足类13种,枝角类4种,其它为毛颚动物、被囊动物、轮虫和原生动物等,桡足类是浮游动物中的主要类群;浮游动物数量和生物量的周年变化基本上为单峰形,高峰期位于8月。回归分析表明,浮游动物数量的变化与水温有一定的相关性。此外,黑石礁海区浮游动物群落小型化趋势较为明显。
From September 2001 to September 2002, the ecology of zooplankton in Heishui Reef of Dalian was investigated. 13 species of copepods and 4 species of cladocera were identified. The others were hairy-jaw animals, tunicates, Rotifers and protozoa, and copepods were the main groups in zooplankton. The annual variation of the numbers and biomass of zooplankton was basically monomodal, and the peak was in August. Regression analysis showed that the number of zooplankton changes with the water temperature has some relevance. In addition, the trend of miniaturization of zooplankton community in Heishui Reef is obvious.
