Time series of net primary productivity and sailfish utilization distribution.
Monthly averages of net primary productivity (2012–2015) and sailfish utilization distribution (UD) on the Campeche Bank (a), East Mexico Shelf (b), Mississippi-Alabama Shelf (c), and in Mexico Basin (d). These areas are selected as utilization hotspots with their boundaries defined by the quarterly 50% UD contours (c.f. Fig. 8). The smaller the UD, the higher utilization an area gets. Notice y-axes are scaled for better visualization.
