The top and bottom basket pans (20, 30) include connection means (22, 24) for connecting the top and bottom basket parts (20, 30) together. The top and bottom basket parts (20, 30) are interchangeable so as to reduce manufacture costs and to make assembly of the basket (10) easier. The top basket part (10), bottom basket part (20) and the at least one door (40) form an enclosure for housing an aquaculture product. The basket (10) typically includes a door (40) at either end of the basket (10). The top and bottom basket parts (20, 30) are typically identical in construction. The invention also relates to an aquaculture basket attachment system.

  • Patent number: 7770861
    Abstract: The invention relates to a protecting apparatus (10) for protecting a structure (100) from an impact. The protecting apparatus (10) is arranged to be mounted on the structure (100) and includes a bumper member (12), a structure positioning member (14) and at least one resiliently flexible joining portion (16). The structure positioning member (14) is arranged in use to be positioned in contact with or adjacent to a portion of the structure (100) being protected. The at least one resiliently flexible joining portion (16) extends between the bumper member (12) and the structure positioning member (14) so that when an outer surface (12a) of the bumper member (12) is impacted, the impact force is dissipated at least in part by flexure of the at least one joining portion (16).
