长江中游渔业资源现状研究
STUDIES ON STATUS OF FISHERY RESOURCES IN THE MIDDLE REACH OF THE YANGTZE RIVER
-
摘要: 长江流域鱼类资源十分丰富,产量约占全国淡水渔业产量的 60%,历史上最高产量达 4217万t[1],是我国淡水鱼最主要的集中产区。多年来,由于水工建设、 环境污染、 酷鱼滥捕等诸多原因,长江渔业资源受到严重冲击[2]。为了摸清长江渔业资源状况,20世纪70年代,农业部组织沿江六省一市协作,进行了长江水系渔业资源调查,对长江主要经济鱼类种群生物学特性、 产卵场等进行了调查研究[3]。20世纪80年代中期,农业部和中国科学院分别对长江渔业进行了调查[4],但近十余年来,未曾对长江渔业资源进行系统调查,作者根据 2001-2003 年的监测结果,对长江中游渔业资源现状进行了研究,以期为科学管理长江渔业资源提供依据。
