生態學
海洋 底中水層性; 海洋洄游的 (Ref. 51243); 深度上下限 50 - 900 m (Ref. 27363), usually 200 - 400 m (Ref. 7061). ; 37°S - 65°S, 165°E - 34°W (Ref. 54589)
There are 2 disjunct populations. Micromesistius australis australis occurs around the Falkland Islands and Argentine Patagonia in the southwest Atlantic; off Chile in the southeast Pacific; also off South Georgia, South Shetland and South Orkney islands. Micromesistius australis pallidus occurs around the South Island of New Zealand.

Max length : 90.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 1371); common length : 60.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 1371); 最大體重: 850.00 g (Ref. 4883); 最大年齡: 30 年 (Ref. 7059)
背棘 (總數) : 0; 背的軟條 (總數) : 43 - 55; 臀棘: 0; 臀鰭軟條: 56 - 71; 脊椎骨: 54 - 57.
Invades shelf waters during summer and concentrating over the continental slope in winter. Forms schools (Ref. 9072). The young feed on euphausiids and amphipods and occasionally on copepods, cephalopods and small fish. Utilized in frozen blocks and as fishmeal. In Japan used as suerii (minced meat) for karaoke (fish cake) (Ref. 27363). Can be fried, microwaved and baked (Ref. 9988).
Oviparous, sexes are separate (Ref. 205).
