Abstract: A primary vessel, such as a flotable float or the like, having a crustacean retrieving means attached to the forward end of the vessel, with the vessel being motor driven, the motor driving a plurality of dasic wheels to maintain the vessel above the water, and allowing it to move on the bottom of the pond. The retrieving means includes a first primary roller positioned substantially the distance of the width of the vessel and moving along the bottom of the pond for distrubing the crustaceans as the vessel moves forward. There is provided the primary conveyor wall directly to the rear of the primary roller wherein the crustaceans moving over the roller are deposited on the conveyor which transports the crustacean upward into a first receiving bin in the vessel. The primary conveyor includes a puralilty of spaced apart shelf members along its width so that the crustaceans will be lodged against the shelf member and will be deposited into the receiving bin as the conveyor belt circulates.

Abstract: A movable vehicle supported by a plurality by a pair of front and rear wheels or tracks, upon which a structural frame is set upon, the vehicle driven by a fuel engine which would in turn power a hydraulic pump for steering, lifting and rotating and other purposes on the vehicle. The vehicle would include primary collection system along its leading edge, which would include a means such as gas and water eductor lines for educting fluid into the pond at a point ahead of the on moving vehicle, so that the crawfish which may be hiding or settled at the bottom of the pond would tend to be disturbed and float to a level within the water in the pond, and urged into the forward moving trapping device by the relative movement of pond water to the vehicle combined with the urging of pressurized water and air floor toward the forward opening of the harvesting device.
