| 摘 要： | 1993-1994年在保安湖主体湖区开展围圈养殖草鱼对浮游生物多样性影响的研究,包括围圈内外浮游动物种类组成、密度、生物量和多样性指数的季节变化等。分析表明,围圈内共有常见浮游动物64种,围圈外共有常见浮游动物55种。围圈内外浮游动物的年平均密度分别为3738和3196ind/L,年平均生物量分别为0.8177和0.8135mg/L,年平均多样性指数分别为3.3808和2.9717.研究结果表明:围圈养殖草食性鱼类对浮游动物现存量以及多样性指数无显着影响。

| Abstract: | In the period of 1993—1994, we carried out an experiment of the effect of cultivating grass carp in the enclosure on the biodive rsity of zooplankton in Baoan Lake. The paper dealt with reported seasonal varia tion of species composition, density and diversity indexes of zooplankton inside and outside of the enclosure, There were 64 species of zooplankton inside of th e enclosure. and 55 species of zooplankton outside of the outside. The biomass a n d diversity index average annual biomass and of zooplankton were 3738ind/L insid e of enclosure and 3196ind/L outside of enciosure respoctively inside and outsid e of enclosure. The average annual biomass of zooplankton were 08177mg/L insid e and 0.8135mg/L outside inside and outside of enclosure respectively. The averag e annual diversity index of zooplankton were 3.3808 and 2.9717 inside and outsid e enclosure respectively. The result showed that cultivating grazing fishes in the enclosure do not influe nce the standing crop and diversity of zooplankton |
