News Release issued by the COI News Distribution Service on 13 August 2009

193/08 Movements of fish into, out of and within a fishery in Cambridgeshire have been restricted, following the confirmation of koi herpesvirus disease.

Cefas, acting on behalf of Defra, has issued a Confirmed Designation prohibiting the movement of fish into, out of and within the affected site. The affected fishery is Long Island Lake, Earith, Cambridgeshire and the designation also includes nearby Earith Carp Lakes.

Under the requirements of the designation both fisheries have been directed to either, establish and maintain on-site facilities for the disinfection of angling equipment at all access points or, to provide anglers with nets, mats and slings for exclusive use on the affected fisheries. Anglers must comply with these requirements.

Samples were taken from Long Island Lake following reported deaths of fish.

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.
