We urgently need catch limits for Blue Sharks and other No Limits? sharks – sign the petition
Common name: Blue Shark
Scientific name: Prionace glauca
Red List status: Near Threatened
Conservation status: Although widespread with a relatively high reproductive rate, the Blue Shark is the most heavily fished shark and declines have been observed. Blue Sharks are highly migratory, requiring management on an international scale.
General information: North Atlantic Blue Sharks are considered to be a single stock though they are highly migratory and exhibit complex movement patterns. Each year Blue Sharks return to UK waters during summer months as part of a large-scale, clockwise trans-Atlantic movement utilising the major oceanic currents. Tagging studies in the Pacific also demonstrate extensive movements – in one case up to 9,200 km. Like many oceanic sharks, the Blue Shark segregates by sex and size, with females more abundant at higher latitudes. Each year, as they run the gauntlet of Spanish and Portuguese longline fisheries for Atlantic Swordfish, Blue Sharks are taken in very high volume as bycatch, yet there are few useful population estimates and much of the catch goes unreported.
