ABSTRACT:
A method and apparatus for harvesting crayfish in a shallow aquatic bed as disclosed. A plurality of one way traps are aligned in a linear array and supported by a frame that extends above the water level. The traps are lowered into the water for a set time of 5 to 120 minutes, and then raised to discharge the collected crayfish into a collection hopper. While the traps are out of the water, the linear array is advanced 3 to 12 meters along an axis substantially perpendicular to the axis of the array. The crayfish are conveyed from the collection hoppers to a single storage tanks by a water sluice conveyor. The trap set and the discharge cycle is repeated until the harvester has traversed the aquatic bed.
