ABSTRACT

The present investigation deals with the haematological and histological altarations in Channa punctatus infected with fungi Aspergillus fumigatus and Aspergillus niger. Fresh water murrels were collected from Hasanparthy and Bhandham lakes and Local fish markets of Warangal district. Isolated fungi from infected fish bodies were identified as Aspergillus fumigatus and Aspergillus niger. The considerable variations have been observed in the mean values of blood parameters. HB content, RBCs, percentage of Monocytes and Neutrophils were significantly decreased by (9%), (55%), (2.4%) and (18%) respectively. WBCs, Lymphocytes, Esinophils and Basophils were found significantly increased (17%), (5%), (5.8%) and (2.7%) respectively. Histopathologically different kinds of destructions were observed in Skin, Gills and Liver of the infected fish. Penetrating fungal hyphae were observed on skin and complete muscles.
