Allocyttus niger James, Inada & Nakamura 1988

Displays seasonally synchronised reproduction.

Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.

Occurs on the continental slope (Ref. 75154).

Found close to the sea bed in deep water. Form large shoals over rough ground near pinnacles and canyons. Juveniles are pelagic and inhabit oceanic waters. They tend to be dispersed over smooth grounds (Ref. 6390). Feed mainly on salps and benthic crustaceans (Ref. 27150). Eggs float near the sea surface and larvae also inhabit surface waters (Ref. 6390). Based on trawl catch rates, there is no evidence of vertical migration during day or night (Ref. 27150).
