  • Patent number: 4276710
    Abstract: A device for harvesting shrimp, prawn, and other aquaculture from man-made ponds. The device includes an elongated truss which is maintained at each end thereof by a carriage. Depending from the truss are a plurality of support arms maintaining at the ends thereof rows of flexible tines. A net extends between the support arms and is connected to the tines. The truss is maintained above the pond with a carriage on each side and is moved over the pond such that the tines contact the pond bottom, stirring aquaculture therefrom and into the net. Preferably, the pond is of a rectangular shape having an inclined ramp at one end thereof, the ramp emptying into a trough, such that the device may move the aquaculture up the ramp and into the trough from which it may be finally harvested.
