摘　　要：为了解丹江口水库(河南辖区)的鱼类资源情况,为丹江口水库资源的合理开发和利用及南水北调中线水源区水质保护政策制定提供理论依据,于2013年10月—2014年8月对丹江口水库(河南辖区)进行了鱼类资源调查。结果显示,共采集到鱼类62种,分别隶属于5目11科49属。其中,鲤形目鱼类占71.0%,鲇形目和鲈形目分别占11.3%。喜流水型鱼类有15种,占丹江口水库鱼类总数的24.2%;喜静水型鱼类共40种,占64.5%;静水生活、流水繁殖型鱼类有7种,占11.3%。对2013年10月份采集的42种渔获物进行分析发现,共采集渔获物8 253尾,总质量为74.30 kg,其中鲤形目最多,占65.36%,其次是鲇形目和鲑形目,分别占13.19%和12.10%,鲈形目占9.35%。从体长组成来看,体长13 cm以下的占95.94%,而体长超过30 cm的鱼类仅占0.19%。可见,丹江口水库鱼类规格偏小,大中型鱼类数量少。In order to understand fish resources and provide theoretical basis for the reasonable development and utilization of the Danjiangkou Reservoir and the policy-making of the water quality protection in the water resource area of the middle route of China＇s South-to-North Water Transfer Project,fish resources investigation of Danjiangkou Reservoir Area in Henan province was made from October 2013 to August 2014. 62 species of fish were collected in this investigation,which belonged to 5 orders,11 families and 49 genera. The Cyprinids accounted for 71. 0% of the total species. The Perciformes and the Siluriformes accounted for 11. 3% respectively. There were 15 species of Rheophilic fish,accounting for24. 2% of the total species. 40 species of Stagnicolous fish accounted for 64. 5%. Seven species of fish living in still water while breeding in flowing water,accounted for 11. 3% of the total fish. 42 catches were collected and analyzed in the lab in October 2013. The result showed that 8 253 fish weighing 74. 30 kg were collected,most of which were the Cyprinids,accounting for 65. 36% of the total fish in the weight. The Siluriformes and the Salmoniformes accounted for 13. 19% and 12. 10% respectively. Perciformes accounted for 9. 35%. The catches with body length shorter than 13 cm were 95. 94% of total,while fish with body length longer than 30 cm was only 0. 19% of the total. The results showed that the fish in the Danjiangkou Reservoir was small,and the middle and large-sized fish was few.
