Abstract:
The present work was conducted to isolate and identify different parasites from Indian Major Carps (IMC). During the study period the Severity of Infection and Parasitic Frequency Index (PFI, %) were also estimated in relation to months, seasons and developmental stages of fishes. For investigative purpose 4 different blocks namely Simlapal, Bishnupur, Taldangra and Onda of Bankura districts of West Bengal were selected considering the potential of fishery resources. Approximately 500 fishes were observed during the entire period of observation between January 2014 to December 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. All parasites were isolated from gill, fins and body surface of the fishes. The isolated parasites were Myxobolus sp., Thelohanellus sp., Dactylogyrus sp., Argulus sp. and Lernea sp. During the study period, among these parasites Myxobolus sp. showed the highest severity and prevalence (PFI, 33%) in winter months compared to it’s zero prevalence in summer. Fry and fingerlings were more susceptible to Dactylogyrus sp., may be due to poor immune power compare to adult fishes. Severity and prevalence of Dactylogyrus sp. is high (PFI, 31.2 %) in summer and 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.
