A study by the North Atlantic Pelagic Advocacy Group (NAPA) and University of Washington Professor Ray Hilborn warns that overfishing could lead to a collapse of the Atlanto-Scandian herring stock in the Northeast Atlantic by 2026. This could result in a historic collapse similar to the one in 1960. The Marine Stewardship Council (MSC) also cautions that climate change-induced warming waters could cause unpredictable shifts in the stocks, exacerbating the situation.
