| 鱼道建设被认为是有效缓解水坝阻隔鱼类洄游的重要方法之一，而鱼道效果监测是评价其功能的重要环节。连江西牛鱼道是广东省第一座建立在水坝主体上的过鱼通道，为了解其运行效果，采用张网法和截堵法，２０１２年３－８月共６次对西牛鱼道的过鱼效果进行监测。研究表明，西牛鱼道共监测到鱼类３目、８科、３０属、３８种，以银鮈（Squalidus argentatus）、乐山小鳔鮈（Microphysogobio kiatingensis）、子陵吻鰕虎（Rhinogobit giurinus）等小型鱼类为优势类群。进入鱼道的鱼类呈现昼夜差异，上午集鱼效果要显著优于其他时间段；不同季节集鱼的种类和数量呈现较大差别，３－８月集鱼数量逐渐减少，集鱼种类数以５月最多。与国内外其他鱼道的过鱼效果比较，西牛鱼道能较好地发挥其功能。 |

| Fishway construction was considered to be an effective way to relieve dam block for fish migration，and monitoring the fishway effect was an important part to evaluate its function. Xiniu Fishway was the first fishway constructed on the main dam in Guangdong province. In order to know its operating effect，net method and section plugging method was used for 6 times from March to August 2012 to monitor its fish pass effect. The research showed that there were 38 species，which belonging to 3 orders，8 families , 30 genera，was captured. Small species，including Squalidus argentatus, Microphysogobio kiatingensis and Rhinogobit giurinus were the dominated species. The effect of the fishway was different between night and day，and the effect in the morning was better than that in other time. In different seasons，the species and quantities of attracting fish was different. The quantities of attracting fish gradually reduced from March to August，and its species in May were more than other months. Compared with other fishways at home and aboard，the Xiniu fishway could better perform its function. |
