The present work was conducted to isolate and identify different parasites from Indian Major Carps. During the study period the severity of infection and Parasitic Frequency Index (PFI, %) were also estimated in terms of month and seasons of fishes. For the investigative purpose different districts of West Bengal were selected considering the potential of fishery resources. For investigative purpose samples were collected from different districts namely Garia, Bamanghata, of South 24 Parganas District, Ulluberia of Howrah District, Memari of Burdwan district for considering the potential of fishery resources. Approximately 360 fishes were observed during the entire period of 12 months between April 2014 to March 2015. The parasite infested fishes were found to suffer mainly from respiratory manifestations, blackness of the skin and mortalities. The parasitic infestations were found to be the major problem and the most prevalent disease causative agents among cultured fish spp. Most of the parasites were collected from gills and body surfaces of the fishes. The isolated parasites were Myxobolus sp., Myxobolus sp., Trichodina sp., Dactylogyrus sp., Lernea sp., Vorticella sp., Chilodenella sp., Argulus sp. and Ergasilus sp. During the study period, among these parasites Myxobolus sp. showed the highest severity and prevalence (PFI, 66.66%) in rainy season. Remaining all parasites were found throughout the year and adult fishes were found to be more infested with these parasites compare to fingerlings.
