 The juvenile black scabbardfish stay to feed and grow for a few years in the fisheries south of the Faroe Islands and the west of the British Isles.Afterwards, the juveniles then move south towards mainland Portugal and even further south to the spawning areas.The most recent studies indicate that the maximum age of the black scabbardfish from Madeira was about 14 years and the maximum age in mainland Portugal was about 12 years.
