Beyond every nation's two-hundred-mile zone lies a patch of the Bering Sea about fifty-five thousand square nautical miles across, fished by foreign factory trawlers pushed out of American and Soviet waters. The pollock catch peaked near 1.5 million metric tons in 1989 and fell to about ten thousand by 1992, and a 1994 treaty bars directed fishing until the stock recovers. More than thirty years later it has not.
The true size of the catch is unknown, since underreporting was suspected. Whether the basin pollock were a self-sustaining stock or overflow from the shelves was never settled, and the cause of the failure to recover is unknown, though overfishing is the accepted cause of the collapse.
