The Convention elaborates a comprehensive regime for governance of the oceans, covering all aspects of ocean space from delimitation to environmental control, scientific research, fishing and other economic and commercial activities, technology and the settlement of disputes relating to ocean matters.
The exclusive economic zone (EEZ), (UNCLOS, Art.55-75), was the most significant innovation in relation to the governance of marine fisheries resources during the second half of the twentieth century. By the time that the LOSC was agreed in 1982, more than 80 coastal states had declared EEZ, mostly of 200nm.
Within this zone the coastal state enjoys "sovereign rights for the purpose of exploring and exploiting, conserving and managing the natural resources, whether living or non-living" (Art.56). The coastal state has the right to set a total allowable catch on the basis of the best scientific evidence available to it (Art.61). This established a legal right for coastal states to manage fisheries off their coasts and establishes a framework within which coastal state can effectively limit access to their fisheries.
Fish Stocks Agreement
In the early 1990s a consensus among states developed that the general provisions of the LOSC requiring co-operation between states in the conservation and management of high seas fisheries resources (Art. 117-120) needed strengthening. This lead to the 1995 Agreement for the implementation of the provisions of the United Nations Convention on the Law of the Sea of 10 December 1982 relating to the conservation and management of straddling fish stocks and highly migratory fish stocks (UN 1995), also known as the United Nations Fish Stocks Agreement.
The Agreement seeks to build upon two provisions of the LOSC. Firstly all states have a duty to ensure that their nationals comply with conservation measures adopted for high seas stocks (UN-LOSC 1982, Art.117). The second provision is that, on the high seas, states have jurisdiction over vessels flying their flag (UN-LOSC 1982, Art. 90-98).
The Agreement provides for the establishment of regional fisheries management organizations. The Agreement sets out comprehensive areas in which such a management organisation will have competence covering scientific research, stock assessment, monitoring, surveillance, control and enforcement (Art. 10). The organization can limit participation by new entrants according to a set of criteria listed in Art. 11.
FAO Code of Conduct for Responsible Fishing
A number of other multilateral agreements further elaborate the evolving set of rules for the governance of fisheries. The Code of Conduct for Responsible Fishing (1995) inter alia spells out flag state responsibilities for the activities of fishing vessels flying its flag and seeks to advance management measures, by agreement among states, that improve the optimal and sustainable use of fisheries resources. The Agreement to Promote Compliance with International Conservation and Management Measures by Fishing Vessels on the High Seas (Resolution 15/93) similarly builds on flag state responsibility for fishing vessels flying its flag (Art. III) and operating on the high seas.
Other significant agreements
Other important agreements which have significant implications for the management of fisheries resources are the 1992 Biological Diversity Convention, the 1982 Convention on the Conservation of Antarctic Marine Living Resources, and the 1972 World Heritage Convention. A range of other global and regional treaties exist which, in some cases, have a direct bearing on the governance of the fisheries sector.
