Biologi     Ordlista (t.ex. epibenthic)

Adults found over rocky reefs, but also common on open bottoms to about 320 m (Ref. 2850). Juveniles are pelagic and settle in near shore nursery areas, then move to deeper habitats (Ref. 36715). Young form schools (Ref. 2850). Feed mainly on fishes, including other rockfishes (Ref. 2850). Ovoviviparous, with planktonic larvae (Ref. 36715, 6885, 34817). Validated age by radiometry is 37 yrs (Ref. 75794). A famous sport fish throughout its range (Ref. 2850). Flesh is of excellent quality when kept chilled (Ref. 27436). Sold with other rockfish species (Ref. 27436).
