ABSTRACT

During the present study sixteen specimens of diseased Labeo calbasu were collected from Halali reservoir, Bhopal. All the fishes were showed external symptoms of fungoid growth on body in form of cottony tufts and in some fishes whole body was found covered with fungus. Isolation and identification of fungi showed the presence of two species of Aspergillus viz. A.flavus and A.terreus on all the collected specimens. Both the species of fungi were found in combination. Experimental inoculation studies showed both the isolated fungi were pathogenic to fish species tested. A.terreus was found more virulent causing 100% mortality of experimental fish. Histopathological studies of skin, muscles, gills , liver and kidney showed marked variations showing necrotization and granulomas formations. No wounds or lesions were observed on body of infected fish.
