Processing whole crayfish to simulate finger lobster serving

Whole crayfish is processed to derive a food serving resembling in appearance a small lobster by deheading the crayfish, making a U-shaped incision around the belly shell encompassing the anal opening of the crayfish, and peeling away the belly shell including the anal opening and the digestive tract still attached to the anal opening, thereby to devein the crayfish and expose the edible flesh contained in the hard shell in a single operation. When subsequently heated during cooking, the flesh tends to curl slightly away from the hard shell for easier extraction.

Crayfish grading apparatus

An apparatus for grading crayfish is provided, comprising a tank having a bottom and sides forming a cavity which will hold water; and a grate assembly having multiple, vertically separated tiers to form spaces between adjacent tiers of sufficient size to accommodate a pre-determined amount of crayfish of pre-determined size. Each tier comprises multiple, horizontally separated round bars, the spacing between the bars in each succeeding lower tier being less than the spacing in the upper tiers. A process for grading crayfish of multiple sizes is also provided, comprising the steps of loading crayfish onto a top tier of a grate assembly of the type described above positioned in a water-filled tank, lifting the grate assembly from the tank after a period sufficient in time to allow all crayfish to seek the lowest level tier achievable in accordance with their size, and removing all crayfish located between one set of adjacent tiers separately from crayfish located between any other set of adjacent tiers.

Pivotable crayfish trap

This invention pertains to the remote harvesting of crayfish by trapping them within a trap submerged in water and then, when harvesting is desired, by applying a counterweight for pivoting the trap so that the trapped crayfish are passed to a line for flushing the crayfish to a collection tank. This operation is accomplished remotely from the harvester and more than one harvester can be connected to the collection tank.

Crayfish harvester boat apparatus

A crayfish harvester boat apparatus having a principal boat portion open ended with side walls and a bottom portion defining a container and occupant space therewithin; a pair of rear drive wheels hingedly mounted to the rear portion of the boat, and a steering wheel hingedly mounted to the front portion of the boat, the rear drive wheels in front steering wheel so mounted to the boat so that upon application of pressure, the boat can be lifted from position flat against the ground to a position substantially above the location of the rear drive wheels and front steering wheels; the power means including hydraulically controlled pistons for lowering and raising the boat between positions. There is further included a power drive system connected onto the rear drive wheels for providing a plurality of drive speeds to the apparatus as it is propelled on land or in water.
