This is not a matter that comes within the remit of my office. However, I am informed by my colleague, Deputy Michael Smith, Minister for Defence, that the main day to day role of the Naval Service is to provide a fishery protection service in accordance with the State's obligations as a member of the European Union. The service is tasked with patrolling all Irish waters from the shoreline to the outer limit of the exclusive economic zone. These patrols are carried out on a regular and frequent basis and are directed at all areas of Irish waters as necessary. Fishery protection patrols are complemented by assistance provided by the Air Corps in the form of aerial surveillance by the two CASA maritime patrol aircraft. Other roles carried out by the Naval Service, generally in support of other Government Departments, include search and rescue operations, aid to the civil power, drugs interdiction at sea, salmon fishery patrols and assistance with oil pollution control at sea.
