Abstract To transfer fry from tanks in a barge to breeding cages immersed wholly or partly in water, use is made of a scraper means consisting of a frame in which a wire net is stretched. The frame is journalled so as to be pivotable about a preferably fixed axis from a vertical to a substantially horizontal position so that all the fish are lifted to the level of the upper edge of the barge hull where a hopper mounted on a hose is placed. The other end of the hose is passed down into a cage, and the fish are then flushed through the hose down into the cage by means of a strong stream of water which is passed into the hopper from a pump. Both the net frame and the hopper may be moved from one tank to another. The tank-defining part of the barge hull is preferably quater-circular in cross-section.
