• Description:
  Rockfish (Sebastes spp.) support a valuable fishery in the northeast Pacific Ocean. Two species in particular, rougheye rockfish (s. aleutian us) and shortraker rockfish (s. borealis), are highly prized for their large size and red color. These two species are managed together as the shortraker rough eye assemblage with commercial catch levels that averaged 2500 metric tons (t) during 1993-97 in areas managed by the North Pacific Fishery Management Council (NPFMC). Both species are particularly sensitive to over exploitation because they are slow growing, have a high age at maturity, and are very long lived. Rougheye rockfish may take approximately 20 years to reach maturity, and individuals have been estimated to live longer than 140 years.
