The Fisheries Monitoring Centre is a specialised unit within the Irish Naval Service responsible for sea fisheries protection and surveillance of all fishing vessels equipped with a Vessel Monitoring System. All Irish vessels operating inside and outside of the Irish EEZ are monitored by the FMC, as are all internationally registered vessels operating inside the Irish EEZ. The FMC has responsibility for operating the Irish Vessel Monitoring System (VMS), an information communications system that tracks vessels via satellite.
