Abstract
The goal of this study was to collect and identify a Mystus vittatus parasite in order to estimate the frequency of helminth infection from fresh water sources in Lucknow. The percentage of prevalence, mean intensity, abundance, and index of infestation of helminth parasites in the Mystus vittatus over various months, seasons, and length groups are summarized in this article. From January to December 2018, a total of 355 fish were checked on a regular basis. Summer (April-June), rainy (July-September), winter (October-January), and spring (Feb- March) were the four seasons studied. Length of host fish were categorized into two ranges, 5-10 cm. and 10.1-15 cm.Among the 355 hosts, 173 were found to be infested with 367 parasites. The highest intensity of Masenia collata was in January and April and the lowest in July. The highest and lowest intensity was in summer and rainy seasons, respectively. The prevalence was highest in large size group of fishes, where the lowest prevalence was found in small group of fishes. Intensity was highest in small length fishes.
