Recent advances in the application of stock identification methods have revealed
inconsistencies between the spatial structure of biological populations and the definition of …

Both old and new information on the biology and ecology of Atlantic bluefin tuna have
confronted scientists with research challenges: research needs to be connected to current …

In principle, the spatial extent of fishery stock assessment should reflect the biological
population, and major fishing patterns or population heterogeneity within the area should be …

Investigations into population structure have been at the forefront of fisheries research for
decades, yet it is generally ignored in stock assessment models. As the complex nature of …

Atlantic bluefin tuna (Thunnus thynnus) is considered to be overfished, but the status of its
populations has been debated, partly because of uncertainties regarding the effects of …

Release and recovery files from the world's five major constituent-based billfish
(Istiophoridae) tagging programs were assembled into a single composite database. Data …

The 'stock concept'in fisheries science conforms to theoretical assumptions of stock
assessment models, including negligible movement across stock boundaries, relatively …

Fishery management decisions are commonly guided by stock assessment models that
aggregate outputs across the spatial domain of the species. With refined understanding of …

Stock assessments provide scientific advice in support of fisheries decision making. Ideally,
