Monogenean trematodes are parasitic Gyrodactylus sp. flatworms that are found on gills of Channa punctatus. The body elongated, dorso- ventrally flattened; body measures 410.5 µ (324-630 µ) in length and width at the pharyngeal level, 94.5 µ (90-108 µ), at middle region, 98 µ (90-108 µ) and at the posterior end, 79 µ (54-90 µ). Anterior part of the body bi-lobed, provided with a pair of antero-lateral papillae and head organs in either lobe. Pharynx is oval 33 µ (31.5 -43 µ) long, 37 µ (34 - 45 µ) wide. It consists of two lobes. The anterior prepharynx 17 µ (11-22 µ) long, 26 µ (25-27 µ) wide, while the posterior pharynx proper 13.5 µ (11- 16 µ) long, 36 µ (31.5 -40.5 µ) wide. Haptor slightly demarcated from the body, sub circular, 68.5 (58.5-94.5 µ) long, 66.5 (54-90 µ) wide with fringed margin, each projection accommodating a hooklet. The prevalence of monogenean parasites in Channa punctatus were recorded during the study period from August 2015 to July 2016. As per Margolis the prevalence of the parasites is 45.04% and mean intensity level of 01.95%, relative density is 0.88% and index of infection is 2.5% to 15.12% represents rare and occasional in the Lower Manair Dam.

Keywords: Monogenean, Gyrodactylus sp, Haptors, Prevalence, relative density, Index of infection.
