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 species. To gain insight into movement patterns, we analyzed data from 66 blue marlin satellite-tagged between 2001 and 2021 throughout the North Atlantic. We recorded migrations connecting west and east Atlantic tagging loc… Show more

“…Mediterranean spearfish in this study preferred the epipelagic environment as suggested in a previous study (Arostegui et al, 2019a), with more than 99% of time spent above 50 m and more than 70% at 0-10 m. Despite the MED being a temperate basin with unique oceanography, the epipelagic behavior was also observed in billfishes living in other oceanic areas (mostly tropical and equatorial) characterized by different physical-chemical features: T. angustirostris (Arostegui et al, 2019b(Arostegui et al, , 2024, M. nigricans (Andrzejaczek et al, 2023), K. albida (Vaudo et al, 2017), T. pfluegeri (Kerstetter et al, 2009), I. indica and K. audax (Rohner et al, 2022). In addition, tagged individuals were observed to spend nearly 99% of their time above the 50-meter mark, suggesting a foraging strategy that focuses on prey within the epipelagic zone (Romeo et al, 2009a(Romeo et al, , 2012.…”

“…However, some differences between night and daylight were observed, with the tendency to occupy deeper depths during the day than night. This was also observed in other billfishes such as T. pfluegeri (Kerstetter et al, 2009), M. nigricans (Andrzejaczek et al, 2023), Kajikia albida (Vaudo et al, 2017), and Istiophorus platypterus (Pohlot and Ehrhardt, 2017) but the reverse of the pattern characteristic of T. angustirostris (Arostegui et al, 2019b(Arostegui et al, , 2024. Furthermore, recent study by Arostegui et al (2019a) reported a maximum depth of 84 m reached by an individual equipped with a PSAT tag, while Nakamura (1985) supposed a vertical distribution not exceeding 200 m. However, we observed for the first time that this species is also able to perform deep excursions into mesopelagic waters, with recorded dives below 200 m and a maximum depth of 322.8 m.…”
