Fishery Catches and Closures
Fishing effort must be distributed across the fishery to reduce localised overfishing. Closures occur for many reasons including resource sustainability and to manage market access risks.
Closures are managed at the level of zones, blocks, sub-blocks, and catch-capped areas, which are strategic groups of adjoining sub-blocks used for fishery assessment. Zone and catch-capped area catches are shown only when five or more divers fished the area.
