A fish cage 1 is formed from an upper square member 2 (above the water line) and a lower buoyant square member of smaller size than the first member 2 and is connected thereto by an upstanding leg 4 at each corresponding corner. Two rows of opposed spaced pairs of fish cages 1 can to be used to form a composite fish farm structure. A central spine of flexibly connected pontoons are provided between the opposed fish cages 1 and are hinged thereto to allow relative movement. A further pontoon acting as a bow turns into the prevailing current or wind to protect the remaining structure. <IMAGE> |
