METHOD AND APPARATUS FOR HATCHING CRUSTACEA

摘要

A tank apparatus and method for providing advantageous environment for the hatching and early development of crustacean larvae. A plurality of hatching chambers, each having an adjacent larval chamber, with a low bulkhead separating the larval chamber from the hatching chamber. Light sources near the larval chambers cause the larvae to migrate to the latter chambers when the water level is above the bulkhead and the screening is removed. A removable screen mesh can be mounted atop the bulkhead to contain the larvae in the larval chamber. A spray arrangement is also provided to wash down the walls forming the larval chamber portion of the hatching tank to prevent larvae from jumping out and air is supplied to the hatching tank.
