摘要
应用沉降法收集浮游植物,评价网箱养鱼对鱼塘水质的影响。通过四季采样,对浮游植物进行群落结构、生物数量、污染指示属、多样性指数、叶绿素A含量等参数的初步研究,结果表明,网箱养鱼对鱼塘水质有明显的影响,且随着鱼体的生长呈现出逐季增加的趋势。
The seasonal changes in ecological features of phytoplankton community such as population densities,biomass,saprobric indicators, diversity index and chlorophy content were studied in this paper. The results showed that there was a significant influence of netbox cultivating on fishpond water quality. And the influ-ence trended to be increased season by season with the growth of fishes.
