Katsuwonus pelamis


Skipjack tuna

Skipjack tuna (Katsuwonus pelamis) is considered a single population in the Western and Central Pacific Ocean (WCPO) for stock assessment purposes (Jordán et al. 2022). In the Pacific Ocean, while skipjack tuna have a continuous east-west distribution, there is evidence of genetic and tagging studies for broad stock separation between the WCPO and the Eastern Pacific Ocean (EPO) (Jordán et al. 2022) (WCPFC 2023). Regular stock assessment is developed by the Western and Central Pacific Fisheries Commission (WCPFC) and the same entity sets conservation and management measures for this stock in this region.

The Parties to the Nauru Agreement (PNA) is a regional binding treaty-level instrument to facilitate cooperation in the management of fisheries resources of common interest. The agreement requires the management of straddling/highly migratory fish stocks on a subregion basis through Regional Fisheries Management Organizations (RFMOs), and the WCPFC Convention (the regional fisheries agreement covering the WCPFC convention area). PNA members are simultaneously members of the WCPFC and so, a single management unit is set for PNA-related profiles. The PNA unassociated (free school) fishery was MSC certified in 2011.


  • Stock assessment is developed regularly and, the most recent (2022) concludes that the skipjack stock in the WCPO is not overfished and is not experiencing overfishing (Jordán et al. 2022).
  • The National Tuna Management Plan of Indonesia has been developed as a product of a joint cooperation between the Directorate General of Capture Fisheries, the Ministry of Marine Affairs and Fisheries of Indonesia and the Western Central Pacific Fisheries Commission (WCPFC). The aim of the management plan is to support the effective implementation of tuna fisheries management in a sustainable way (MMAF 2012). Indonesia has also launched a National Plan of Action for tuna, skipjack and neritic tuna in November of 2014 (MMAF 2014).
