生态学
海洋 底中水层性; 海洋洄游的 (Ref. 51243); 深度上下限 50 - 900 m (Ref. 27363), usually 200 - 400 m (Ref. 7061). 溫帶; 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.
有 2個分離的族群。 Micromesistius 南極光南極光 在大西洋西南部的福克蘭群島與阿根廷的巴塔哥尼亞的周圍出現; 在太平洋東南部的外海智利; 也外海的南喬治亞州，雪特蘭群島南方部與奧克尼群島南方部島。 Micromesistius 南極光 pallidus 紐西蘭的島南方部的周圍出現。

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).
侵入大陆架水域夏天时而且集中冬天时在大陆斜坡之上。 形成鱼群。 (参考文献 9072) 幼鱼吃磷虾与片脚类动物与偶然地在桡脚类的动物，头足类动物与小鱼上。 在冷冻鱼块与制成鱼粉中利用了。 在日本对于卡拉 OK(鱼肉炸饼) 用作了鱼肉酱 (切碎了肉) 。 (参考文献 27363) 能被油炸, 微波而且烧烤。 (参考文献 9988)
Oviparous, sexes are separate (Ref. 205).有 2個分離的族群。 Micromesistius 南極光南極光 在大西洋西南部的福克蘭群島與阿根廷的巴塔哥尼亞的周圍出現; 在太平洋東南部的外海智利; 也外海的南喬治亞州，雪特蘭群島南方部與奧克尼群島南方部島。 Micromesistius 南極光 pallidus 紐西蘭的島南方部的周圍出現。
