Fig. 3. Comparison of reported harvests from the “Donut Hole” and Aleutian Basin to biomass levels of age 5 and older pollock in the Aleutian Basin‡. The solid curve in the top panel is the catch in the Donut Hole; the dotted line is the total reported catch in the Aleutian Basin. The gray vertical line marks the peak of harvests, showing that it occurred well after the decline of biomass in the Aleutian Basin (data from Ianelli et al. 2006).
