摘要

Pop-up satellite archival tags were deployed onto four wahoo during 2006 in the western North Atlantic (~26.5°N, 79.3°W), providing movement, depth, and temperature data collected over a total of 198 days. Straight-line distances between tag deployment and pop-off positions ranged from 162.5 to 1,960.0 km. Wahoo spent >90 % of their time in water <200 m, and >90 % of their time in water between 17.5 and 27.5 ℃. Three fish made regular trips to depths >200 m. All four fish had significantly different depth distributions between the dark and light periods (Kruskal-Wallace test, p < 0.001). The median mean depth for all fish combined was 29.7 m during the dark period (Q1 = 18.8 m, Q3 = 46.2 m) and 50.7 m during the light period (Q1 = 22.3 m, Q3 = 112.3 m). This research improves an otherwise poor understanding of wahoo movements and depth/temperature distributions and suggests potential interactions with other members of the pelagic fish community, many of which are commercially important and either fully or over-exploited.
