LARGE PELAGIC FISHES
Large pelagic fishes such as tunas, marlins, swordfish, and some sharks are predatory species inhabiting the world's open oceans. These fishes are broadly distributed and capable of making long distance movements spanning hundreds to thousands of miles. Many large pelagic fishes are commercially or recreationally important in regions across the globe; however, limited information on species biology challenges the management of fisheries that interact with these species.
My research on large pelagic fishes focuses on the application of genetic tools to explore spatial and temporal patterns of genetic variation among populations and species. This work provides insights into broad-scale genetic connectivity, barriers to gene flow, and regional adaptation in the marine environment, as well as practical information on stock structure and genetic diversity important for ensuring the short- and long-term persistence of populations. Research questions representative of this work are highlighted below.
