Abstract: Background and Objective: Fish are an important group of vertebrates and are frequently challenged by different types of infectious disease, some of which are caused by helminth parasites. The main aim of this study was to study the prevalence of helminth parasites in Schizothorax plagiostomus and Cyprinus carpio communis which is an important source of dietary protein for people in Kashmir and plays an important role in this region’s local economy. Materials and Methods: This study was conducted to study the helminth infection of 768 fishes belonging to 574 Schizothorax plagiostomus and 194 Cyprinus carpio communis fishes collected from different sites of Nallah Sukhnag in Budgam, Kashmir. Results: Helminths recovered from S. plagiostomus were Diplozoon kashmirensis (trematoda), Adenoscolex oreini (cestoda) and Pomphorhynchus kashmirensis (acanthocephalan) with prevalence of 10.27%, 11.84% and 12.54% respectively. Helminth parasites reported from C. carpio communis were Bothriocephalus acheilognathi (cestoda) with prevalence of 4.63% and P. kashmirensis (acanthocephalan) with prevalence of 6.18%. Gender wise and size wise prevalence in S. plagiostomus and C. carpio communis showed maximum prevalence percentage of helminths in males and larger fishes in comparison to females and smaller ones, respectively. Conclusion: Based on the observations as gathered in the present study, the occurrence of maximum infection in larger fishes could be due to accumulation of larvae from year to year. This study also concluded that helminth prevalence in fish is mainly dependent on fish feeding habits, pollution of water body, type of fish as well as on their defence system.
