As the ANP is a member-oriented institution, the anNA presidency plays a fundamental role both as a spokesperson and as a consensus within the group. Unlike other regional organizations, where chairs are actively occupied only during annual Council meetings, the presidency of the PHA requires a considerable investment in time throughout the year. Catches of fisheries controlled by standards, rules and decisions agreed between the parties to the Nauru agreement amount to several billion dollars per year and decisions may have to be taken at any time to maintain these fisheries in the event of new challenges. The anNA presidency is elected annually by the parties. The Nauru Agreement on Cooperation in Fisheries Management of Common Interest or the Nauru Agreement is a sub-regional oceanic agreement between the Federated States of Micronesia, Kiribati, the Marshall Islands, Nauru, Palau, Papua New Guinea, Densalomonen and Tuvalu.  The eight signatories together control 25-30% of the world`s tuna supply and about 60% of the tuna supply in the western and central Pacific.  Historically, the Nauru Agreement and other joint fisheries management agreements concluded by the contracting parties to the Nauru Agreement (usually known as ANPs) have focused on the management of purse seine tuna in the western tropical Pacific. All fisheries management instruments implemented by the contracting parties to the Nauru Agreement are as follows: in December 2011 the OPEN-air fishing OF the ANP was certified as sustainable by Marine Stewardship Council standards.  This means that products made from skipjack tuna manufactured by free schools (near Fish Aggregation Devices or other floating objects) by PNA-certified and chain-certified purse seiners are eligible for the MSC label.
The PNA-Freischul-Skipjack-Purse-Senne-senne fishing is one of the largest fisheries certified by the MSC. In May 2012, ANP fisheries ministers met in Alotau, Papua New Guinea, as part of a resolution on marine animals.  pledged to take stricter management measures in their joint EEZ agreement to maintain sustainable tuna fishing and minimize the impact on bycat already Among the new measures adopted by the parties the Nauru agreement includes a ban on the cessation of purse seine nets around whale sharks and a ban on fishing near fish aggregation devices during the months of July. , August and September (with the possibility of extending it for an additional three months if scientific advice indicates that tunad would benefit), a requirement for 100% observation coverage on board seiners, a minimum mesh size and a requirement to conserve all tuna on board (no releases). The ANP was named 2010 Organization of the Year by the regional news magazine Islands Business.  At the May 2012 meeting in Alotau, Papua New Guinea, fisheries ministers also approved an ANP business plan and hosted the Tokelau as part of the Palau Arrangements Purse-Seine Vessel Days Management Scheme. PNA received the Seafood Champion Award for Vision at the Global Seafood Summit in Malta in 2016.  According to the Environmental Justice Foundation, the ANP received the award “for the need for long-term management of the tuna fishery in the western and central Pacific and the need for timely and effective action.” In October 2010, the eight parties to the Nauru Agreement (NAP) extended their ban on tuna fishing to approximately 4.5 million square kilometres of high seas in the Pacific Ocean by purse seine vessels licensed to fish in their combined exclusive economic zones.  Enlargement was presented at the 6th meeting of the Technical and Compliance Committee of the Western Pacific Fisheries Commission (WCPFC).
