Solution
The correct option is C Branchiomyces sanguinis
Gill rot disease (Branchiomycosis) in fishes is caused by Branchiomyces sanguinis and Branchiomyces demigrans. It is a fungal disease involving gill tissues, affecting the most species of freshwater fish. It is characterized by areas of infarction necrosis of the gills, anorexia, and marpling appearance of the gills. Fungal spores are transmitted by water to gills. These spores adhere to the gills, germinate and produce hyphae. The hyphae penetrate gills epithelium or within the blood vessels of gills. Hence, option C is correct.
