The present investigation was conducted on fungal diseases of fresh water catfishes. Total 95 fish specimens were
observed. Different parts of body of fishes were found infected and showed clinical signs. The clinical signs are variable
on different fish species. The fungi isolated from infected areas on the fishes were cultured on different media including Malt Extract Agar (MEA),
Sabouraud Dextrose Agar (SDA) and Potato Dextrose Agar (PDA) was prepared. The agar plates were incubated at 28-30°c and fungal growth
was observed after 4-7 days. The fungal colonies of white, grey, black, brown, green and orange colours were observed. The slides were prepared
and stained with Lacto phenol cotton blue.
Three different genera of fungi were identified as Aspergillus, Penicillium and Saprolegnia. Aspergillus and penicillium were isolated from
Clarius batrachus and Wallago attu and Saprolegnia was isolated from both Clarius batrachus and Mystus seenghala. All three species of
catfishes shows incidence of fungal parasites, Clarius batrachus shows (57.89%) which was highest, followed by Wallago attu (52.94%) and
Mystus seenghala was found less affected (43.47%).
