মন্তব্য সমূহ | Adults found between 500-800 m depth while the oceanic young stages between 70-200 m. The young feeds mainly on copepods while the large ones on euphausiids, hyperiids and mesopelagic fishes. Adults undertake far-ranging feeding migrations (outside the spawning season) to the slope areas of Europe, North America and West Africa. Spawning probably occurs in midwater far offshore, with a concentration in the Sargasso Sea (Ref. 6689). |
