Seasonal Variation Of Helminthic Infestation In Relation To Length And Gender Of Fish Hosts In Two Districts Of Western U.P.

[Full Text]



Dr. Shalini Roy Neelam kumari



Prevalence, seasonal variation, helminthic fauna, infection.



Present study was conducted to evaluate the prevalence of helminth infected fishes in relations to various aspects such as seasonal variation, length and gender of host. The study underscores two years observations from Jan 2017 to Dec. 2018 that highlights the heavy helminthic burden in edible fish Channa punctatus collected from Moradabad and Sambhal districts of Western U.P. Four study areas were selected to collect the samples from both the districts. From the total host examined within two years due to harbouring of these helminths parasites prevalence was found highest in large sized fishes (69.90%) and furthermore females were observed more susceptible to infections as recorded in our data (68.86%) in comparison to prevalence of infection in male (61.19%). Our investigations further showed that the highest prevalence (72.69%) of helminthic fauna was found in monsoon season and least (59.79%) was observed in pre-spring and spring season. The helminthic fauna isolated from the host consist of adult digeneans, metacercariae, cestodes, nematodes and their eggs.
