Life Cycle
provided by Fishbase
Spawning happens between the months of September and January at 250 m depth. Females lay great egg bunches in nests built on the ground. The size of the eggs increases with the size of the female. Egg size 5-6 mm, larval length at hatching 21-24 mm.
Migration
provided by Fishbase
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.
Trophic Strategy
provided by Fishbase
Inhabits offshore waters over soft bottoms, often with boulders, from 25-590 m, but most common from 100-400 m (Ref. 4694). Benthic (Ref. 58426). Feeds mainly on echinoderms, but also crustaceans, mollusks, fishes (Ref. 4694) and worms (Ref. 58426). In Barents sea, it reached at least 80 cm, age 9 years. Preyed upon by cod, pollock, and Greenland shark (Somniosus microcephalus). Parasites of the species include 1 myxosporidian, 1 cestode, 7 trematodes, 1 hirudinean, 1 crustacean and 1 protozoan, Trypanosoma murmanensis (Ref. 5951).
