【摘要】 四川妙音水库1987～1988年网箱养鲤取得几项结果:1.两年中浮游藻类种类无显著变化,但群落组成变化很大。1987年优势种为小球藻、十字藻和栅列藻,1988年为鱼腥藻和隐藻。网箱内增加了水绵、竹枝藻、丝藻等固着藻类。库内和网箱内浮游藻类生物量1988年较1987年显著增加;2.两年中浮游动物的群落组成相似,只是箱内增加了固着生物的某些种类,如聚缩虫、累枝虫等。浮游动物生物量1988年比1987年显著减少;3.妙音水库网箱养鲤后,使水体营养化加剧。提出了相应的网箱养鲤的技术措施。更多还原

【Abstract】 This paper presents the results of the influence of pankton on culturing carp in cages of Miao-yin reservoir in sichuan Provence, during 1987-1988. Which are as follows:1. phytoplankton species no major changes in two years, bat Community composition have shown considerable variation.The phytoplankton was dominated by Chlorella,Crusigenida. and Scen-edesmus in 1987. Anabena and Cyptomonas was dominated in 1988. Spirogyron, Draparnaladia and Ulothrix of peripyton has increased in cages. Phytoplankton biomass in 1988 has increased in abun dance than 1987.2. The community composition of zoopankton in 1988 similar to 1987, defferent from increasing some species example Epistylis sp., zoothamnium arbuscula etc. of attaching organism in cages, zooplankton biomass was considerable decreased in 1988 than 1987.3. Eutrophication of miaoyim reservoir has been increasing through cultural carp in cages, some suggestions regarding the management of the fishcultural technique in cages are Proposed.更多还原
