Abstract

A feed-spreader for use in the feeding of fish, the feed-spreader (1) being arranged to be mounted at the outlet of a feed hose (3), so that an air flow mixed with feed in the feed hose (3) flows through the feed-spreader (1), which comprises a rotor (5), the rotor (5) comprising a tubular socket (6) arranged to change the direction of the air flow mixed with feed, so that the resulting reaction power provides a torque, acting on the rotor (5), rotating it around an axis of rotation (7). A projection of the cross-section of the inlet of the rotor (5) along the axis of rotation (7) overlaps a part of a corresponding projection of the cross-section of the outlet of the rotor (5).
