The present study was carried out with an objective to asses the population dynamics of trematode in fish Mastacembelus armatus (Lecepede, 1800) An extensive survey for digenetic trematode parasite of fresh water fish Mastacembelus armatus (Lecepede, 1800) was conducted in Osmanabad district (M.S.) India for the period of June 2018 to May 2019 for collection of parasites visceral organ of fishes were taken out and dissected separately in petridishes with saline water, near about 120 fishes were dissected, out of which 38 were found infected and 76 trematode were collected from the various organ such as the gall bladder, intestine, liver of the fish for present study. The population dynamics includes incidence, intensity, density and index of infection. The infection rate was in the order of rainy, winter followed by summer respectively. The study indicate that environmental factors and feeding habitat, intermediate hosts influence the parasitic infection.
