摘　　要：2003年以来,对扁吻鱼Aspiorhynchus laticeps(Day)唯一栖息地的生物饵料及鱼类群落环境进行了初步研究。结果显示,克孜尔水库有浮游植物7门、34种(属),平均密度145.7×104个/L,平均生物量1.225mg/L,硅藻密度及生物量均占优势;浮游动物35种(属),平均密度958.6个/L,原生动物占优势;平均生物量1.449mg/L,枝角类和桡足类占优势;底栖动物1种(属),平均密度9.1个/m2,平均生物量0.08g/m2;水生植物2种(属)。栖息地分布鱼类隶属2目、3科、19种,土著种10种,外来种9种;其中鲤科15种,占78.9%,鳅科3种,占15.8%,鰕虎鱼科1种,占5.3%。探讨了扁吻鱼所面临的生态环境问题。The author conducted a preliminary study on the live feeds and fish community of the only habitat of Aspiorhynchus laticeps(Day) since 2003. The results showed that: There were 34 species (genus) of phytoplankton. The average density and biomass of phytoplankton was 145.7×104 ind/L and 1.225 mg/L,respectively. Diatom was dominant in the density and biomass. There were 35 species (genus) of zooplankton. The average density and biomass of zooplankton was 958.6 ind/L and 1.449 mg/L,respectively. Protozoa was t...
