This book examines the international law of high seas fisheries in the light of the negotiations of the Third United Nations Conference on the Law of the Sea, the State and international practice that followed and its influence on the 1995 Straddling Stocks Agreement. This Agreement and related developments are discussed in detail, particularly in terms of the interactions with the Exclusive Economic Zone and the introduction of environmental perspectives that have led to major conceptual changes in the legal approach to fisheries and practical solutions in the field.
