Habitat & Distribution
Widely distributed off the coasts of Britain and Europe this benthopelagic and demersal species inhabits the upper Continental Shelf. It is seasonally migratory in northern waters, seeming to move offshore during autumn/winter months. During the 1980s it was regularly caught by long-line in the Falmouth Bay area, mainly between August and January. There are now strict national controls on the quantities that can be landed. It is on the IUCN Red List as ' Vulnerable' and is also on the UK List of Priority Species.
