Max length : 95.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 1371); common length : 50.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 1371); common length :60 cm TL (female); 最大年龄: 6 年 (Ref. 83871)
背棘 (总数): 1; 背的软条 (总数): 43-52; 臀棘 0; 臀鳍软条: 36 - 41; 脊椎骨: 50 - 53. Gill rakers short and thick with blunt tips. Pectoral fins relatively short, not reaching level of anal fin origin. Color is silvery with golden luster on back, silvery white on belly (Ref. 1371).
鳃耙短与厚的与钝的顶端。 胸鳍相当短的, 不达到臀鳍起源的程度。 色彩是银色的有金的光彩背面, 银白色在腹面上.(参考文献 1371)
Adults inhabit continental shelf depths mainly between 100 and 200 m (Ref. 1371). Larger individuals feed on fish (anchovies, hake, nototheniids, myctophids and Southern blue whitings), squids and macrozooplankton (euphausiids and amphipods); smaller individuals feed on mysids and amphipods (Ref. 1371). Migrate inshore during spring and summer, and offshore into deep water wintering areas after spawning; also undertake diel vertical migrations (Ref. 1371). Sold fresh and frozen.
在 100 与 200 公尺之间主要地栖息于大陆架深度。 (参考文献 1371) 较大的个体吃鱼 ( 鱼，鳕鱼， nototheniids, 灯笼鱼科鱼类与南方蓝色的牙鳕) ，乌贼与大型浮游动物 (磷虾与片脚类动物); 较小的个体吃糠虾与片脚类动物。 (参考文献 1371) 回游沿海地区在春天与夏天期间, 而且离岸进入在产卵之后冬天区域的深水域; 也进行日周期性的垂直性回游。 (参考文献 1371) 生鲜贩卖了与冷冻的。
