Due to overfishing, the total North American Pacific herring fishery collapsed in 1993, and is slowly recovering with active management by North American resource managers. In various sub-areas the Pacific herring fishery collapsed at slightly differing times; for example, the Pacific herring fishery in Richardson Bay collapsed in 1983. The species has been re-appearing in harvestable numbers in a number of North American fisheries including San Francisco Bay, Richardson Bay, Tomales Bay, Sitka Sound, Half Moon Bay and Humboldt Bay. In other areas, such as Auke Bay, which, in the late 1970s was the largest harvestable stock of herring in Alaska, the species remains severely depleted.
