POPULATION STRUCTURE AND FORAGING AGGREGATION OF SEA TURTLES IN THE GULF OF MEXICO

The Gulf of Mexico provides critical foraging habitats for neritic loggerhead, green, Kemp’s ridley, and hawksbill turtles, all of which are listed as threatened or endangered under the U.S. Endangered Species Act. Despite the importance of the region to these four species of marine turtles, a coordinated in-water research and monitoring network does not exist. This hinders our understanding of the marine turtle population structure and abundance in the region, habitat use, movement, and their trophic ecology, which is essential to diagnose causes of decline and to inform and advance management. Therefore, the overarching objectives of this project are to 1) investigate marine turtle seasonal distribution and movement within and among habitats and   2) collect information on their population structure to potentially diagnose declines, inform and advance management, and evaluate the efficacy of recovery actions.
