Although the so-called black cod- also known as sablefish or gindara in Japanese- does not belong to the cod family, it lives in deep waters, generally below 200 m.
It spawns in late winter and early spring in waters of the continental slope.
The eggs incubate near the bottom but, after hatching, the larvae rise to surface waters.
Juvenile Black cod, called fry, are found in shallower water close to shore, but they soon move to deeper offshore waters.
Larvae and juveniles feed on planktonic crustaceans while adults are considered “opportunistic” feeders, taking benthic fishes and invertebrates, squid, and jellyfish.
