生態学
海 深海魚; 海洋回遊性 (Ref. 87829); 深さの範囲 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).
初回成熟時の長さ / サイズ / 重さ / 年齢
成熟: Lm 33.2, range 25 - 43.3 cm
Max length : 53.0 cm TL オス/雌雄の選別がない; (Ref. 56527); 最大公表体重: 2.1 kg (Ref. 56527); 最大記録サイズ: 103 年 (Ref. 93933)
背面の脊椎 (合計) : 13; 背鰭 (合計) : 14 - 17; 肛門の骨: 3; 臀鰭: 6 - 9; 脊つい: 26. 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).
