There has been some publicity [eg here and here] over the last few days about the enlarged area of the Pacific high seas that the Parties to the Nauru Agreement have declared closed to purse-seining, but nobody seems to have shown a map of it yet.
Below is a representation of the closed area. The green shading is the existing high seas pockets purse-seine fishing closure, and the yellow shows the extended area that was announced last week.
This closure comes into effect for purse-seine tuna fishing vessels that are licenced to fish in PNA waters by PNA countries. Any vessel that fishes in this closed high seas area will not be allowed to fish in PNA Exclusive Economic Zones.
