Regional areas used in the halibut fishery are assigned to the following PMFCs: QC=5E, PR=5D, NC=5D, CC=5B, WC=2D, SG=4D. PFMA areas are assigned PMFC areas using PFMA centroids in PMFC polygons.

1 Note that in Fig. 3 all AO grid cells with fewer than three fishing vessels have been excluded due to privacy concerns. These grids are, however, included in all AO calculations.
