Branchiomycosis of pond-cultured eels

Abstract

In July, 1972, branchiomycosis broke out among eels(Anguilla japonica) in a eel-culturing pond at Saijo, Ehime Pref., Japan, and caused considerable mortality.The causative agent was closely related to Branchiomyces sanguinis PLEHN.The width of the hyphae measured from 10 to 30 μThe spores in the hyphae were from 4.5 to 7μ in diameter.The hyphae were located in the tissues of the gill filaments, not growing from the gills outwards.
