[ABNJ Ocean Partnerships] Current Knowledge, Key Uncertainties and Future Research Directions for Defining the Stock Structure of Skipjack, Yellowfin, Bigeye and South Pacific Albacore Tunas in the Pacific Ocean (Information Paper)
A recent workshop organised by the Pacific Community has made significant progress in identifying the likelihood that each of the four tropical tuna species is comprised of separate stocks (self-replenishing populations). The workshop also identified the investments needed to identify the number, size, distribution and behaviour of all stocks comprising a tuna species in a Pacific Ocean context, and developed a strategic plan to implement this foundational research. The workshop and subsequent work identified a draft ‘Strategic Plan to Identify the Stock Structure of Tropical Pacific Tuna’. The investments involved in the sampling and analyses required to identify the stock structure of each tuna species are considered to be an urgent priority, given the great significance of tuna to Pacific Island economies and the mobility of tuna species. This report provides a comprehensive technical review on a species by species basis of the methods applied to date, and current knowledge of stock structure.
