SYNCHRONOUS HATCHING METHOD OF EGG OF KING CRAB SPECIES

摘要

PROBLEM TO BE SOLVED: To provide a technique that is used for mass-producing seedlings (zoea) of king crab species by synchronously inducing hatching of eggs of the king crab species.SOLUTION: A synchronous hatching method of crab eggs of king crab species such as king crabs, abra crabs and Hanasaki crabs is characterized by repeatedly performing next steps (A) and (B). (A) is a step of taking out brooding female crab of king crab species from the inside of a breeding aquarium and exposing the female crabs in a gas-phase. (B) is a step of returning the female crabs in the breeding aquarium and breeding the female crabs while recovering the hatched zoea.SELECTED DRAWING: Figure 1
