Prevalence of Argulus sp. in mrigal fish (Cirrhinus mrigala) from the bheries of West Bengal, India

Abstract

Fishes from the bheries of West Bengal are generally not affected by severe diseases but still some common parasitic diseases may occur time to time. The present study has been carried out to investigate the Mrigal fish for the prevalence of Argulus sp. A total of two hundred adult Mrigal fish (Cirrhinus mrigala) from the different bheries of West Bengal were randomly sampled and examined for ectoparasites. A. foliaceus, and A. japonicus were the species of Argulus which found in all the cases. Out of 200 examined fish 32 (16%) were infested with ectoparasites. A. foliaceus (12%) parasite was found predominant in the study followed by A. japonicus (9.50%). Most of the infested fishes indicate the prevalence of A. foliaceus.
