Abstract
Eight zoosporic fungi viz.,Achlya debaryana, A. flagellata, A. klebsiana, Aphanomyces laevis, Saprolegnia diclina, S. ferax, S. parasitica, andPythium sp. were isolated from a large number of adult fishes of the speciesMastacembelus armatus, Mystus vitatus, Nandus nandus, Tor putitora andT. tor of Nanak Sagar reservoir in Naini Tal district, India. Species of the parasites and the hosts were different in their pathogenicity and immunity, respectively. However,A. flagellata andS. parasitica appeared to be the most virulent. The severity of mycosis was primarily correlated to moderate water temperatures of 22–25 °C. High temperature (>28 °C) retarded the disease process. The experimental inoculation with all the associated fungal species onPuntius conchonius in the laboratory produced clinical signs similar to the ones seen on infected fish in the reservoir. This is the first report on fish mycosis in the large reservoir located in the foot hill of Kumaun Himalaya.
