Koi herpesvirus (KHV) disease has been confirmed in carp (Cyprinus carpio) at Puddledock Farm Fisheries, Essex
An outbreak of KHV disease has been confirmed at Puddledock Farm Fisheries, St Mary’s Lane, Upminster, Essex.
The site is now subject to statutory controls to prevent or limit the spread of the disease. The Fish Health Inspectorate (FHI) at Cefas, acting on behalf of Defra has issued a confirmed designation prohibiting the movement of fish to, from and within the fishery complex.
Fishery equipment disinfection and movement control measures are also now in place and anglers must ensure that they comply with all biosecurity measures within the designated area.
The fishery manager reported the problem to the Fish Health Inspectorate for further investigation and voluntarily closed the affected water.
KHV has no implications for human health. It is nonetheless, a serious viral disease of fish, and is notifiable in the United Kingdom. KHV affects all varieties of common and ornamental carp (Cyprinus carpio) including carp hybrids and can result in high rates of fish mortalities.
Clinical signs of KHV disease may include white or necrotic patches on the gills, rough patches on the skin, sloughing mucous and sunken eyes. These signs usually appear when water temperatures are between 16 and 28 degrees centigrade. Anyone noting deaths in carp or carp hybrids, with signs of disease similar to those above, or have suspicion of notifiable disease in any aquatic animal, should immediately contact the FHI.
Anyone who imports, keeps, fishes for, or retails carp (common and ornamental) and carp hybrids should take precautions to prevent the spread of KHV.
