A cage is for farming fish. The cage floats in a water column and the upper portion of the cage has a surrounding floating body arranged to float in a water surface. An enclosure is located between the upper portion and the lower portion of the cage, the enclosure being closed in its lower portion and forming an inside and an outside. The cage has a liquid-tight wall which is attached to the floating body and which extends from the water surface downwards in the water column. The liquid-tight wall forms a lower edge portion. The cage is provided, in its upper portion, with at least one flow booster for creating a circular water current within the liquid-tight wall. A method for creating an upward water current of fresh water within the cage is also provided.
