  • Patent number: 4551938
    Abstract: Method for retrieving lobsters or similar objects from the floor of a lobster pound or other shallow water body are described. An upward flow of water is established in a flexible conduit or passageway of size sufficient to accommodate the objects to be lifted. This is accomplished by a low pressure air lift particularly suited for non-traumatic handling of lobsters. Objects to be lifted are drawn into the upward flow as the flexible conduit is moved over the bottom. As objects rise to the surface they are guided or diverted by a transfer guide chamber or coupling onto a conveyor which carries the objects onto a deck or support platform floating above the water surface. The transfer chamber and conveyor shed water away from the lobsters or other objects. The transfer guide chamber, conveyor and a pivotable boom for supporting the flexible conduit in an "S" configuration are attached to a deck or support platform floating above the surface.

  • Patent number: 4357902
    Abstract: A specially adapted container for transporting lobsters or other marine organisms in an aerated water environment is in the basic configuration of a drum housing with removeable cover and vent hole. A low pressure air diffuser is positioned in the drum housing at the base for releasing diffuse low pressure air into sea water contained in the drum. Air coupling for delivering low pressure air to the diffuser is provided along with inlet and outlet openings for circulating fresh sea water in lieu of diffuser aeration. Different covers for the container may be provided for loading by the fisherman and for subsequent transport. The invention further includes a complete system for containerized transport of lobsters by truck or other vehicle in the aerated water environment provided by the containers. The method of the invention provides for handling and transporting lobsters in aerated sea water from a boat at the dock to a lobster pound or similar destination. The method may be completely automated as disclosed.
