Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
Maturation seems to occur at the same time rather than in the same season both in the northern and southern hemisphere, which could be suggestive of homogeneity of the population of this species. Females probably spawn once a year (Ref. 4770).大西洋: 廣泛分佈於離岸水域, 更加濃密地如此在西方者中超過在東大西洋中。 高度遷移的種,1982年海事法會議的附件一.(參考文獻 26139)
