The demand for the fish in Korea is very high , and fisheries often employ the services of fish hatcheries for breeding more of the fish to supplement and enhance the supply of stock . This has been done to such a degree that some . As many as 95 alleles have been found to be unique to one of the populations , resulting from minor variations in certain genes that occur exclusively within either population ; genetic differentiation between S. cirrhifer born in the wild and those bred in a hatchery has apparently occurred .
