The modalities for detailed implementation of the United Nations agreement referred to are a matter for the party states and other parties to the agreement to decide from time to time, in light of conservation and management imperatives and best use of available surveillance and enforcement resources. Concerted international action in implementing the agreement should serve as a strong deterrent to over-fishing and so help minimise enforcement costs for Ireland. Enactment of this Bill is a prerequisite to enabling Ireland to ratify the agreement and become a party state thereto.
