Habitat & Distribution
A small oceanic and benthopelagic species which inhabits the Continental Slope and Shelf down from a depth of 100m to more than 1000m. It is found off northern and western Scotland, in the northern North Sea, off the south and west coasts of Ireland, south-west England and the Celtic Sea. It is not commonly recorded off the Cornish coastline but at times it can occur in large numbers, so much so, as to be a ' nuisance' to trawlermen, especially in deeper offshore waters. The main population in British waters spawns from February to May around the Irish coast, before moving to the Norwegian coastline. Its great abundance at times, has led to an increasing commercial interest in this species for processing as fish-meal, and it is an important economic fish, which, however, is being subjected to over-fishing. It has been placed on the UK List of Priority Species.
