abstract
The present study was conducted to study the distribution of two monogenean parasite and the biodiversity of different fish species in Barganatu Dam, FR Bannu, KPK, Pakistan. A total of 180 species of fish were collected from Barganatu Dam. Out of 180 fish, a total of six species of fish were examined and identified. During the study, two Monogenean parasite were identified, namely Dactylogyrus vastator and Gyrodactylus spp. Dactylogyrus were the most prevalent gill parasite observed, followed by the prevalence of Gyrodactylus in fish species. The infection rate were also studied, showing a high infection rate of 120 out of 180 in fish species by Dactylogyrus vastator. The low rate of infection in fish were studied 44 (24.45%) out of 180 by Gyrodactylus Spp. Present study concludes that Monogenean parasite namely Dactylogyrus species and Gyrodactylus species, were the most common parasites found in Barganatu Dam.
