Abstract

The histopathological studies on freshwater fungal disease fishes were carried out during the period from feb 2018 to march 2019 in the Lake of Hasanparthy Warangal District. Symptoms of fungal disease freshwater fish species Channa punctatus showed variation among the species and its distribution. The fungi were first identified on the body surface and tip of the gills of fishes and attach themselves on the surface by their powerful sucking devices. The histopathological observations were appeared that gills and body surface were the main infested areas and gill filaments were damaged by the Aspergillus flavus and Penicillium sps. The histochemical studies were shows the disease caused extensive damages to the blood elements by rupturing blood capillaries, causing necrosis, coagulation and haemorrhage.
