A floating raceway 10 for the rearing of fish comprises a fish-rearing region through which water is passed, the raceway having buoyancy which will support it such that when it is floating on water, the water in the fish-rearing region is at a higher level that the outside water on which it is floating, and the bottom 12 when the raceway is floating on water slopes downwardly from a water inlet to a water outlet. <IMAGE> |
