The poxvirus causes a disease known as ‘koi sleepy disease’ in both koi and common carp.
The fish kill was first reported at The Lough in Cork city centre last week, with subsequent reports at Belvelly Lake in Cobh. Some 450 carp were removed from the former, and over 20 from the latter, as well as live samples from both for analysis.
At present, while tests are ongoing and further tests are carried out on the CEV detected, this is being treated as a ‘suspect positive’ and is not confirmed as the causative agent of the mortalities until all tests have been completed.
Inland Fisheries Ireland (IFI) recommends that stringent biosecurity protocols continue to be implemented. All mortalities continue to be removed and disposed of in a bio-secure manner.
Angling remains suspended at both locations, as well as at Inniscarra and Carrigadrohid Reservoirs.
