PREVENTIVE FOR BACTERIAL INFECTION FOR LARVA OF FISH AND SHELLFISH AND RAISING OF LARVA OF FISH AND SHELLFISH

摘要

PROBLEM TO BE SOLVED: To obtain a preventive for bacterial infection for a larva of fish and shellfish capable of effectively preventing the bacterial infection of the larva of the fish and shellfish and suitably used for raising, etc., of the larva of the fish and shellfish by including a protease inhibitor. SOLUTION: This preventive for bacterial infection for a larva of fish and shellfish includes a protease inhibitor (A) such as a serine protease inhibitor, a metalloprotease inhibitor and a cysteine protease inhibitor (e.g. an ovomacroglobulin, 2 macrogloblin or these analogue because of safety and excellence in an effect inhibiting the increase of bacteria). The preventive is preferably used in 1-100mg, preferably 10-30mg expressed in terms of an amount of A based on 1kg aqueous solution or seawalper for raising the larva of the fish and shellfish (e.g. the larva having =300m size of the shellfish such as an abalone, and a prawn such as Peneus japonicus.
