Biodiversity and prevalence of helminthes parasites of Nalganga dam fishes of Buldana district (M. S.)

Abstract

The present study will be helpful for biodiversity status of helminthes parasites found in Nalganga Dam. A total of 300 fishes were examined from which about 50% fishes were infected with cestode parasites and 50% with nematode parasites. Present study suggest that cestodes mainly Circumoncobothrium spp, Senga spp., Lytocestus spp., Polyoncobothrium spp., and nematodes mainly Eustrongylides spp., Rhabdochona spp., Syphaciella spp., Contracaecum spp., Ascardia spp.,and Trichuris spp., are the main intestinal parasites of Nalganga dam fishes (viz. Mastacem bellusarmatus, Wallago attu, Ophiocephalus punctatus, and Clarius batrachus) are the main intestinal parasites of Nalganga dam fishes. The incidence of parasite infection was higher in winter season whereas intensity of infection was higher in Mansoon.This report summarizes the data of incidence, intensity, and index of incidence in fresh water fishes in relation to environmental factor. Present study is carried out during July 2019 to June 2020.
