通过1988年4月至1989年4月的生态调查表明,福清柯屿围垦水域的浮游动物种类组成比较复杂,经鉴定有79种,包括淡水—半咸水、沿岸低盐和外海广高盐性的种类。各生态类群的分布范围比较稳定,显示了围垦水域水流滞缓的态势,同时,沿岸种和外海种在围垦水域的分布状况,可启示围垦内、外水体交换的动态。浮游动物数量较集中在10月至翌年4月出现,夏季较贫乏,和水产养殖动物的大量摄食有关。
According to the ecological survey conducted from April 1988 to April 1989, the species composition of the zooplankton in the reclaimed waters of Keyu Island in Fuqing County was rather complicated. There were 79 species identified, including freshwater-brackish water, coastal salt and seawater with high salinity kind of. The distribution of ecological groups is relatively stable, which shows the stagnant water flow in the reclaimed waters. At the same time, the distribution of coastal and marine species in the reclaimed waters can reveal the dynamics of the exchange of water bodies within and outside reclamation. The numbers of zooplankton were more concentrated in October to April than in the following year, with the poorer in summer, which was related to the large feeding of aquatic animals.
