Prevalence of epizootic ulcerative syndrome (EUS) in carps
Abstract
In present study examination of fishes, present in 15 fish ponds, were done for the infestation of EUS in Chitwan, Nepal. Nine ponds or 60% of them were recorded infested and confirmed to be EUS positive. Among 1491 fish samples examined, 170 fish samples were found with lesions and 165 of them were confirmed to be EUS-positive. Two culture fish species like Labeo rohita and Catla catla was found to be containing lesions among different fish species. So, they were sampled for histological study. Other fish species like common carp, silver carp, grass carp and bighead carp were not found to be EUS positive. The risk of EUS infestation was found high in fish ponds connected with paddy fields and flooded water supplying wild fish species. Ponds with poor management and use of contaminated nets also had a high risk of EUS infestation.
