Advances in Electronic Tagging (e-tags) and Genomics Offer New Insights Into Understanding the Life History of Atlantic Bluefin Tuna (ABT) Populations in the North Atlantic and Adjacent Seas. Despite the Rapid Advances in Research in This Field, Key Questions Remain. Knowing the Number of Populations, Their Biological Parameters, and the Spatial Boundaries Over Which Abt Fishery Populations Interact Has Far-reaching Implications for Species Management and Conservation. Current Abt Fisheries Models Are Hindered by the Lack of Consensus on the Number of Abt Populations, Their Migratory Patterns, and the Level of Mixing on Foraging and Spawning Grounds. Management Models Are Highly Sensitive to Assumptions About the Spatial Mixing of Populations, and Estimations of Survivorship and Recruitment. Here, We Propose to Use Acoustic and Satellite Tagging of Abt to Assign Stock Specific Mortality Estimates, Map Stock-specific Spatial-temporal Movements at High Resolution in the North Atlantic, a
