2 Fig. 1 Trends in the distance traveled to fish from 1950 to 2014.
Trends in the distance traveled to fish from 1950 to Mean distance to fishing grounds for the world’s 20 largest industrial fishing countries (by tonnage) grouped by expansion history: (A) rapid and continuous expansion, (B) expansion followed by retrenchment, and (C) limited expansion. Percentage of global catch over the past decade is shown at the top of each panel. Countries not labeled in (C) are Argentina, Chile, Iceland, Malaysia, Mexico, Morocco, Philippines, and United States. David Tickler et al.

4 Fig. 3 Trends in total catch and area fished by global industrial fisheries, 1950–2014.
Trends in total catch and area fished by global industrial fisheries, 1950–2014. (A) Global industrial fisheries catch (8), (B) percentage of ice-free ocean area exploited, and (C) industrial catch per unit ocean area. Dashed line indicates year of peak global catch in 1996, with percentage growth/decline since 1996 labeled on each time series. David Tickler et al.

5 Fig. 4 Spatial mapping of the distribution and intensity of industrial fishing catch.
Spatial mapping of the distribution and intensity of industrial fishing catch. Mean industrial fisheries catch in metric tons per square kilometer by catch location during the (A) 1950s and (B) 2000s. David Tickler et al.
