Red List Status

Largely caught as a bycatch of other fisheries, this is also a valuable food and sports fish that appears very vulnerable to overfishing, unable to sustain intensive, targeted fisheries for long periods. Some regional populations have been severely depleted, e.g. in the Northeast Pacific. However, population and fisheries data are lacking from many regions.
