دريايي موجوداتی که در اعماق زیر 200 متر زندگی و تغذیه می کنند; اقیانوس رو (Ref. 87829); تغييرات عمق 0 - 825 m (Ref. 6793), usually 165 - 293 m (Ref. 27437). Deep-water; 64°N - 24°N, 143°E - 110°W (Ref. 54884)
North Pacific: Honshu, Japan to Cape Navarin in the Bering Sea (but not in the Sea of Okhotsk) and La Jolla, California, and along the Aleutians from Stalemate Bank and Bowers Bank to the Alaska Peninsula. Stocks have suffered severe population decline due to overfishing (Ref. 27437).

Head spines weak - nasal, preocular, supraocular (may be absent), postocular, tympanic, parietal, and nuchal (may be absent) spines present, coronal spine absent (Ref. 27437). Long lower jaw with prominent forward directed symphyseal knob (Ref. 27437). Posterior margin of caudal indented (Ref. 6885). Bright to light red, usually with dark markings dorsally, may have some dark stippling on sides and dark blotch on caudal peduncle (Ref. 27437).
Body shape (shape guide): fusiform / normal.
Abundant in offshore waters (Ref. 2850). Young pelagic up to age 3 (Ref. 6885). Grows slowly (Ref. 2850). Viviparous (Ref. 34817). Very important commercial rockfish in the North Pacific (Ref. 2850, 27437) and are considered as one of the straddling stocks in the northwest Pacific (Ref. 87829). Marketed as fillets (Ref. 2850). Utilized fresh and frozen; eaten fried, microwaved and baked (Ref. 9988).
Produces young in small numbers, only about 300,000 when the fish is 20 years old.
