The adults usually live near to the sea floor, but sometimes they also appear near the surface (Ref. 1371). They perform diurnal vertical migrations (Ref. 1371). They mainly feed on krill (Ref. 39882) but they also eat fishes and crustaceans (Ref. 6885). The adults which are spawning are often solely captured for their roe. The meat is used to produce Surimi (this is an imitation of shellfish meat) (Ref. 28499). They are traded as fresh fish, boneless flesh, in frozen blocks or as Surimi. The fish is cooked in the microwave, steamed or fried in butter (Ref. 9988).
