Movements of fish into, out of and within three fisheries have been restricted, following the confirmation of Koi Herpesvirus disease.

Cefas, acting on behalf of Defra, has issued Confirmed Designations prohibiting the movement of fish into, out of and within the affected sites.  The designated fisheries are as follows:

Koi Herpesvirus disease affects all varieties of carp (Cyprinus carpio), including common carp, mirror carp, ghost carp and koi carp and can result in high rates of fish mortalities.

There are no implications for human health.
