柔鱼(Ommastrephes bartrami)的分布范围很广,在太平洋分布于10°～50°N和20°～40°S之间、在大西洋分布的纬度范围与太平洋相似、在印度洋分布于该洋西部10°N～30°S之间,以北太平洋的数量最多,栖息海域的水温为10～24°C。柔鱼栖息于表层至1500m的水层,它具有季节性洄游和垂直洄游习性,在摄食季节,往往在夜里游至表层摄食,并具有较强的趋光习性,有利于灯光诱钓作业。
Ommastrephes bartrami is distributed widely in the Pacific Ocean between 10 ° -50 ° N and 20 ° -40 ° S, similar to the Pacific Ocean in the latitudes of the Atlantic Ocean and in the western Indian Ocean in the Indian Ocean ° N ~ 30 ° S, with the largest number in the North Pacific, and the water temperature in the habitat is 10 ~ 24 ° C. Tail fish habitat in the surface to 1500m of the water layer, which has seasonal migratory and vertical migration habits, during the feeding season, often at night to surface feeding, and has a strong phototaxis habits, is conducive to light fishing operations.
