Straddling stocks are fish stocks that pass through or are located in more than one exclusive economic zone. The agreement was adopted in 1995 and came into force in 2001.  The review conference, held in New York from May 22 to 26, 2006, was tasked with assessing the effectiveness of the agreement in ensuring the conservation and management of straddling and large migratory fish stocks, verifying and assessing the adequacy of its provisions and proposing, where appropriate, ways to strengthen the content and methods of implementation of these provisions in order to better address persistent conservation problems and management of these stocks. The agreement strives to achieve this goal by establishing a framework for cooperation in the conservation and management of these resources. It promotes good governance in the oceans through effective management and conservation of offshore resources, including setting detailed minimum international standards for the conservation and management of straddling fish stocks and large migratory fish stocks; Ensure that conservation and management measures for these stocks are compatible and consistent in areas under national jurisdiction and on the adjacent high seas; Ensure that effective mechanisms are in place to ensure compliance and implementation of these measures on the high seas; and recognising the specific conservation and management requirements of developing countries, as well as development and participation in fisheries for the two types of stocks mentioned above. The Territorial Fisheries Convention () is a multilateral treaty concluded by the United Nations to improve the cooperative management of large fishing areas that cover large areas. and are of economic and ecological interest to a number of nations. In December 2016, the treaty was ratified by 91 parties, comprising 90 states and the European Union.  Highly immigrant fish is a term that originates in the United Nations Convention on the Law of the Sea. It refers to fish species that migrate marineally and also have a wide geographical distribution and generally refers to tuna and tuna, sharks, marlins and swordfish.
Straddling fish stocks are particularly vulnerable to overfishing due to ineffective management systems and non-compliance with fishing interests.
