中文摘要:
      通过对乌鳢(Channa argus)养殖池塘和对照水体即排水区和南阳湖的比较研究,探讨了乌鳢养殖对浮游动物群落结构的影响。研究表明,乌鳢养殖池塘的浮游动物物种数24种,密度1 032 ind/L,均明显低于周边水体(排水区64种,密度1 995 ind/L;近湖区65种,密度2 569 ind/L),而其生物量达4.65 mg/L,高于周边水体(排水区3.10 mg/L,近湖区2.85 mg/L),这主要是由于养殖池塘浮游动物生物量以枝角类、桡足类和无节幼体等大型浮游动物(95.70%)为主体,原生动物和轮虫所占比例(4.30%)相对较小,而周边水体则以原生动物和轮虫为主体;养殖池塘优势种为大型溞(Daphnia magna)和萼花臂尾轮虫(Brachionus calyciflorus),亦不同于周边水体的优势种;综合分析浮游动物优势种和多样性指数的评价结果,池塘水体呈中度污染,排水区水体呈轻度-中度污染,近南阳湖水域达到了轻度污染水平,这表明乌鳢养殖对周边水体造成了一定程度污染。
英文摘要:
      The effects of snakehead (Channa argus) culture on zooplankton community structure were studied by the comparative research of snakehead culture pond to surrounding areas including drainage region and Nanyang Lake. The results showed that species number (24 species) and density (1 032 ind/L) of zooplankton in snakehead pond were dramatically lower than those of surrounding areas ( the species number was 64 and 65, the density was 1 995 ind/L and 2 569 ind/L in drainage region and near lake region, respectively), while biomass (4.65 mg/L) was significantly higher, which may be attributed to that biomass in snakehead pond was mainly composed of macrozooplankton (95.70%) such as Cladocera, Copepoda and Nauplius, while micro Protozoa and Rotifera have a lower proportion (4.30%), but they were the main component in surrounding areas. Different from the surrounding areas, the dominant species in pond were Daphnia magna and Brachionus calyciflorus. Comprehensive analysis of dominant species and diversity index showed that snakehead pond was moderately polluted, drainage region was mildly to moderately polluted, while waters near Nanyang Lake was slightly polluted, which indicated that snakehead culture had resulted in pollution in surrounding areas.
