The United Nations Fish Stocks Agreement (UNFSA) represents a major international effort to improve fisheries governance, resource recovery amd sustainable development of international fisheries. Straddling fish stocks and highly migratory fish stocks are especially vulnerable to overexploitation because of ineffective management regimes and non-compliance by fishing interests. This book explains the international legal framework, summarizes the state of the fisheries, and outlines the efforts of regional fisheries management organizations (RFMOs) to adopt and implement key elements of UNFSA. Includes matrices and maps of RFMOs.
