Claim:
A method for processing a large number of fish eggs, providing: an egg case having an egg-arranging plate on which a large number of concave portions are formed at predetermined positions on an upper surface of the egg-arranging plate; an egg-arranging apparatus for arranging each fish egg into each concave portion of the egg-arranging plate; and an injecting apparatus for injecting materials to a large number of the fish eggs arranged in the concave portions; wherein the production method comprises the steps of: a first case-setting step for setting the egg case at the predetermined arranging position of the egg-arranging apparatus; an egg-arranging step for arranging each of fish eggs in each of the concave portions by means of draining water through the concave portions; a second case-setting step for setting the egg case at the predetermined injection position of the gene-injecting apparatus; and an injecting step for injecting materials to a large number of the fish eggs arranged in the concave portions of the egg-arranging plate wherein each of the concave portions has each drainage-through-hole through which the water in each of the concave portions flows downwardly; the egg case holds a cover plate capable of sliding on the egg-arranging plate; the cover plate opens the concave portions, when the cover plate is positioned at a first position; and the cover plate closes the concave portions, when the cover plate is positioned at a second position.
