サケ及びサクラマスの各生活期における Aeromonas salmonicida 保有状況
In the previous paper, we reported that Aeromonas salmonicida was isolated from mature chum salmon (Oncorhynchus keta), pink salmon (O. gorbuscha) and masu salmon (O. masou) without signs or furunculosis. In the present study, we determined the prevalence of A. salmonicida in immature chum salmon wi...
