Quantifying overlap between the Deepwater Horizon oil spill and predicted bluefin tuna spawning habitat in the Gulf of Mexico
Abstract Atlantic bluefin tuna ( Thunnus thynnus ) are distributed throughout the North Atlantic and are both economically valuable and heavily exploited. The fishery is currently managed as two spawning populations, with the GOM population being severely depleted for over 20 years. In April-August...

Abstract Atlantic bluefin tuna ( Thunnus thynnus ) are distributed throughout the North Atlantic and are both economically valuable and heavily exploited.
