Beware of the sharp gill covers and dorsal spines of rockfish when handling them. Most species of rockfish have similar brain locations and all can be very tolerant of air exposure. They should be killed humanely by iki jime, or a firm knock to the head before placing them in an ice slurry after bleeding.

  • Blue rockfish occur on the west coast of the USA from Mexico north to Canada , Alaska and the Aleutian Islands.
