The primary fishery habitats are reef walls formed by the cliffs and large boulders (or "calves" as analogous to the chunks that fall off of icebergs) that have been dislodged from the cliffs, scattered patch reefs and hardbottom areas on the 25-30 m terrace, and deeper reef slopes and shelves (>30 m) farther offshore that have not been well described.
