EGG SETTLEMENT INDUCING SUBSTRATE FOR SHELLFISH, AND SHELLFISH SEED COLLECTION METHOD AND CULTURE METHOD USING SAME

摘要

An egg settlement inducing substrate for shellfish includes: an iron member containing metallic iron; and a carbon member constituting an egg settlement inducing portion, wherein the carbon member is provided on an outer periphery of the iron member so that the carbon member and the metallic iron in the iron member are at least partly in contact with each other. This egg settlement inducing substrate has high and stable seed collection efficiency, and also the time for installing the egg settlement inducing substrate does not depend on the time of spawning and emergence of larvae in the settlement period.
