Now it has developed into a large-scale shrimp farming industry in western Japan, producing 600 tons of shrimp each year. The Japan Fisheries Agency has provided substantial financial subsidies for the production and release of shrimp, placing shrimp in the sea each year, making it one of Japan’s major natural fisheries resources. Bacteriological studies have gained more attention as prawn farming techniques are developed, as some bacteria associated with shrimp cause disease and others seem to be able
