Seasonal and diel habitat use of blue marlin Makaira nigricans in the North Atlantic Ocean
Abstract Knowledge of blue marlin, Makaira nigricans, movement patterns across a range of spatiotemporal scales is important for understanding the ecology of this epipelagic fish, informing responsible management strategies, and understanding the potential impacts of a changing ocean climate to the...
