崔家营航电枢纽工程鱼道过鱼效果

崔家营航电枢纽工程位于长江中游支流汉江上,是一个以航运为主,兼有发电、灌溉等综合开发功能的项目.为了减免工程对鱼类资源的不利影响,崔家营航电枢纽工程采取了修建鱼道的保护措施.为了解崔家营航电枢纽工程鱼道的过鱼效果,2012年9月19-26日,采用网具回捕和水声学监测结合的方法,对通过鱼道鱼类的种类、规格、数量和生物学性状进行了调查.结果表明,采用三层流刺网在鱼道内共捕获到11种鱼通过鱼道上溯,包括瓦氏黄颡鱼、吻鮈、鳊鱼、蛇鮈、马口鱼、圆吻鲴、犁头鳅、铜鱼、鳜鱼、鲢、（）,其中数量较多的为瓦氏黄颡鱼、（）和圆吻鲴;水声学监测了1267 min,共获得658个目标信号,平均每分钟获得0.5个目标,...

Summary:崔家营航电枢纽工程位于长江中游支流汉江上,是一个以航运为主,兼有发电、灌溉等综合开发功能的项目.为了减免工程对鱼类资源的不利影响,崔家营航电枢纽工程采取了修建鱼道的保护措施.为了解崔家营航电枢纽工程鱼道的过鱼效果,2012年9月19-26日,采用网具回捕和水声学监测结合的方法,对通过鱼道鱼类的种类、规格、数量和生物学性状进行了调查.结果表明,采用三层流刺网在鱼道内共捕获到11种鱼通过鱼道上溯,包括瓦氏黄颡鱼、吻鮈、鳊鱼、蛇鮈、马口鱼、圆吻鲴、犁头鳅、铜鱼、鳜鱼、鲢、（）,其中数量较多的为瓦氏黄颡鱼、（）和圆吻鲴;水声学监测了1267 min,共获得658个目标信号,平均每分钟获得0.5个目标,总体体长均值为33.50 cm,95%置信区间为30.43~36.55 cm.崔家营航电枢纽工程鱼道的建成和运行,为大坝上下游鱼类的交流和完成生活史提供了渠道,对保护汉江的渔业资源具有重要意义.

The Cuijiaying navigation-power junction project is located at the Hanjiang River. Its functions include, but are not limited to, navigation, power generation, and irrigation. In order to compensate for the adverse effect of the project on the fishery resource, a fish passage was built. To realize the effect of the fish passage, an investigation was conducted September 19-26, 2012 and the methods of net catch and hydroacoustic monitoring were adopted. Trammel nets were used for fish catching in the fishway. The net was comprised of three layers and the dimensions of the net were 15m×1.2m. The mesh of the middle layer was 4mm and the mesh of the outer two layers was 8mm. Nets were laid at the orifices of the baffle plate and six nets were put out every day, three in the daytime and the other three in the nighttime. The first net was put in the exit of the Cuijiaying fishway and the distance between the net and the exit was 8 meters. The distance
