An outbreak of Koi herpes disease has been found at a country park in Newstead.
The Fish Health Inspectorate (FHI) has confirmed Koi herpesvirus (KHV) disease in fish at 12 sites across the country, including waters at Newstead and Annesley Country Park.
As a result of the outbreak, the popular fishing venue has now had strict controls enforced on it, restricting the movement of aquatic animals in the designated area, which can be viewed HERE.
The government website explains that sites with KHV disease must undergo a formal monitoring programme for the duration of the calendar year immediately following the outbreak.
The FHI will visit these sites to look for evidence of disease and to inspect compliance with the conditions of the statutory controls in place.
The controls will be removed if the disease doesn’t reoccur during this period.
What is Koi herpesvirus (KHV) disease?
KHV is a serious viral disease of fish that affects all varieties of common and ornamental carp species (Cyprinus carpio) and can result in large scale mortalities.
It affects all varieties of common and ornamental carp species (Cyprinus carpio) and can result in large scale mortalities. Fish with KHVdisease may show the following signs, especially when water temperatures are between 16 to 28 °C:
• necrotic (white or brown) patches on the gills
• rough patches on the skin and sloughing mucous
• sunken eyes
What happens after an outbreak of Koi herpesvirus (KHV) disease?
When the FHI confirm an outbreak, they take steps to control and, wherever possible, remove the disease. This may involve movement controls on susceptible species in the affected area, enhanced biosecurity, culling of fish, and cleaning and disinfecting of the premises.
Once statutory controls are in place the site operators must write to the FHI to get permission to move live fish into, out of, or within the designated area, and to make material changes to the site or site activities. This also applies to fish eggs and gametes.
