In accordance with the ‘Voisinage Agreement' between Ireland and the United Kingdom, registered fishing vessels from Northern Ireland are permitted to fish within Ireland's exclusive fishery limits on the same basis and under the same conditions as Irish registered vessels, for as long as Irish registered vessels enjoy similar reciprocal rights to fish within the exclusive fishery limits of the United Kingdom in the waters surrounding Northern Ireland. This Agreement applies to all species of fish. The Voisinage Agreement is a so-called ‘neighbourhood agreement' under the London Fisheries Convention 1964 and was memorialised by an exchange of letters between Ireland and the United Kingdom in 1965.
