The First Report on Saprolegnia parasitica and Neoparamoeba perurans Isolated from Atlantic Salmon ( Salmo salar ) Reared in Korea
This study is the first report of parasite and fungal disease separated from domestically reared Atlantic salmon in Korea; the characteristics of the pathogens were identified, and histopathological analysis was conducted. Fungal and parasitic diseases were detected in Atlantic salmon and were isola...

External symptoms observed in Atlantic salmon infected with S . parasitica include fin ulcers and hemorrhage, abdominal hemorrhage, and necrosis of the gills and gill covers. The histopathological analysis results showed necrosis, hemorrhaging, and inflammatory cell infiltration in the abdominal muscles, while only inflammatory cell infiltration was observed in the gill covers.
