A device (1) for fish sorting comprises a fish entrance having one or several openings for sorting by size fish entering the device (1), and an exit including a closing device allowing fish to exit the sorting device (1) and at the same time not allowing fish to enter the sorting device (1) through the exit. Advantageously, the entrance comprises a disc (2) having several through-holes (3, 4, 5) of different diameters rotatably mounted on a plate (6) provided with corresponding holes (8). The rotatable disc (2) can on rotation be adjusted for optional passage of fish of different sizes. Advantageously, the exit is a net funnel (11), of which the wide end is facing the entrance part and the narrow end is equipped with the closing device. |
