Abstract
The present study was aimed to investigate the fungi found associated with mycotic infected fishes collected from Upper Lake. Infected fishes were observed weekly in the fish catch from December -2018 to May-2019. Infected fishes showed the symptoms of eroded scales, ulcerations on the skin, cottony growth on body and on eyes. In laboratory mycological examination of fishes have been done with 98 fishes belong to eight different species viz. Labeo rohita, Labeo calbasu, Ctenopharyngodon idella, Channa gachua, Chanda ranga, Hypopthalmichthys molitrix, Puntius sophore and Puntius ticto. Most affected fish species was Puntius sophore (20.4%). From the infected fishes 228 isolates were cultured and maximum number of isolates (38) have been collected from Labeo rohita in which many parts were found infected. Identification of isolates revealed the presence of eight different genera of fungi viz. Alternaria sp., Aspergillus sp., Cladosporium sp., Curvularia sp., Fusarium sp., Mucor sp., Penicillium sp. and Rhizopus sp. Aspergillus was found to be most prevailing genera contributing (32.8%) of the total isolates and minimum isolates recorded were from Curvularia (2.6%).Temperature range 28-30 °C found to be supportive with other factors for the growth of fungi and causing mycotic infections.
