A feed spreader for use in a fish pen is disclosed, wherein the spreader including: a base portion provided on a buoyant structure; an impeller rotatably mounted to the base portion, with the impeller being rotatable about an approximately vertical axis when the spreader is in an in-use orientation; the base portion including fluid flow path, the fluid flow path extending between a fluid inlet and a fluid outlet; the fluid inlet for receiving fluid flow from a fluid source, and the fluid outlet being directed at the impeller, such that, in use, fluid exiting the fluid outlet does so with sufficient pressure to cause the impeller to rotate relative to the base portion; a feed nozzle having a feed flow path extending between a nozzle inlet and a nozzle outlet; the nozzle inlet for receiving feed from a feed supply; and the nozzle outlet provided for directing feed outwardly from the nozzle and into the fish pen; wherein the nozzle is connected to the impeller, such that rotation of the impeller about the approximately vertical axis causes the nozzle to rotate about the approximately vertical axis. |
