A method for taking fish up from a body of water comprising the steps of providing a duct (14) having a lower open end below the water surface and an upper open end arranged at a floating working platform (5) above sea level; introducing water into the duct (14) from the upper open end to give a water stream from the upper open end of the duct to the lower open end of the duct; and allowing the fish to swim up in the duct against the water stream therein. The incoming water is directed to flow into the duct, and the fish is separated from the flowing by means of a grating (16) inclining upwards from the top end of the duct to a separation plate (17) arranged above the water level in the duct. A device for taking up fish, using the mentioned method is also described. 种从水体捕获鱼的方法，包括以下步骤：提供具有在水表面下方的下部敞开端部和布置在海平面上方浮动工作平台(5)处的上部敞开端部的管道(14)；将水从上部敞开端部引入至管道(14)中以得到从管道的上部敞开端部至管道的下部敞开端部的水流；和允许鱼在管道中逆着管道中的水流向上游动。进入的水被引导成流动至管道中，且鱼借助于从管道的顶部端部向上倾斜至布置在管道中的水位上方的分离板(17)的格栅(16)与流动分离。还描述了使用提到的方法捕获鱼的设备。
