The United Nations Convention on the Law of the Sea (LOSC) established the broad framework for the conduct of distant water fishing. It did this by establishing the legal regime for exploitation of fisheries resources in coastal States' Exclusive Economic Zones (EEZs) by foreign fishing vessels and by starting to curb traditional high seas freedoms. Coastal States were accorded rights
to fisheries resources in the EEZ coupled with sustainable use obligations. In some cases untrammelled high seas fishing freedoms do not commence immediately seaward of the EEZ limit because of the link between EEZ and high seas resources. The developing international regime recognises the need to have effective management of straddling and migratory stocks, including anadromous and catadromous stocks.
