Author(s): Dr. Shiva Narayan Yadav
Abstract: 58 (fifty eight fresh water fishes (Heteropneustes fossilis = 22, Clarias batrachus = 20, and Mystus vittatus = 16) were collected from different fresh water ponds in the Takuwa-11, Rangeli municipality; morang eastern Nepal and brought to the department of zoology lab. All fishes were examined and investigated helminth parasites. The study revealed that all (100%) H. fossilis were infected with acanthocephalon- Pomphorhynchus sp. 80% only 16. C. batrachus infected with one cestoda-Lytocestus and 75% of 12 of M. vittatus infected with nematodes Rhabdochona magna. The mean intensity of infection was 15.27 in H. fossilis, 6.25 in M. vittatus and 7.5 in C. batrachus. The results indicate that the parasite intensity is high. It may due to the physical factors that favour the completion of life cycles of these parasites.
