摘要
为了解河南省信阳市出山店水库冬季底栖动物群落结构及鱼产潜力,于2024年2月对水库不同区域的底栖动物进行了调查。结果表明,出山店水库冬季底栖动物群落结构以摇蚊幼虫和寡毛类为主,平均密度为1000 ind./m^(2),平均生物量为3.01 g/m^(2),Shannon-Wiener多样性指数平均值为0.93。Mantel test和RDA分析结果表明,氨氮和总氮是影响底栖动物群落分布的主要环境因子。出山店水库冬季底栖动物鱼产潜力为12.48 kg/hm^(2),冬季底栖动物鱼产潜力为1.99×10^(4)kg。
In order to explore zoobenthic community structure and fish production potential of zoobenthos in the Chushandian Reservoir in winter,a survey of zoobenthos in different areas of the reservoir was carried out in February 2024.The results showed that the winter zoobenthic community structure was dominated by Chironomidae larvae and Oligochaetes.The average density of zoobenthos was 1000 ind./m^(2),the average biomass of zoobenthos was 3.01 g/m^(2),and the average value of the Shannon-Wiener diversity index of zoobenthos was 0.93.The results of the Mantel test and the RDA indicated that NH4+-N and TN were the principal environmental factors affecting the distribution of the zoobenthic community.The fish production potential of zoobenthos in the Chushandian Reservoir in winter was 12.48 kg/hm^(2),which equated to an estimated fish production potential of zoobenthos in winter of approximately 1.99×10^(4)kg.
