摘要:
于1998年5月-1999年5月对江苏省48座大中型水库底栖动物进行了调查.鉴定的底栖动物计75属种,优势种类为尾鳃蚓属(Branichiura)、水丝蚓属(Limnodrilus)、管水蚓属(Aulodrilus)、长足摇蚊属(Pelopia)、隐摇蚊(Cryptochironomus)等5属.底栖动物密度为288.4ind./m2,变动范围43.2-928.2ind./m2;生物量为8.753g/m2,变动范围0.235-61.884g/m2.北部、中部、南部水库各类底栖动物的季节变化呈现较大的差异.用Goodnight&Whitley生物指数和Wright寡毛类密度法评价水库水质,除少数水库有轻度污染外,水质状况总体良好.用能量估算法估算水库底栖动物的平均渔产潜力为5.8kg/hm2.

Abstract:
The investigation of zoobenthos was conducted in 48 reservoirs of Jiangsu Province from May 1998 to Jan.1999.A total of 75 taxa of zoobenthos were recorded, of which Branchiu-ra, Limnodrilus, Aulodrilus, Pelopia, Cryptochironomus were dominant.The density and biomass of zoobenthos were 288.4 ind./m2 (43.2-928.2)ind./m2 and 8.753 g/m2 (0.235-61.884 g/m2) respectively.The density of zoobenthos in southern reservoirs was higher than that of central and northern reservoirs, while the biomass of zoobenthos in northern reservoirs was greater than that of central and southern reservoirs.The seasonal change of standing crops of different groups of zoobenthos were significant.The Goodnight biotic index of zoobenthos as indicator of water quality show that there was no pollution in most reservoirs.It was calculated that the potential fishery production capacity from zoobenthos was 5.8kg/hm2.
