Atlantic blue marlin
They are sought after as a highly prized game fish by anglers and are also caught by commercial fishermen, both as a directed catch and as bycatch in major industrial tuna fisheries.  Blue marlin are currently considered a threatened species by the IUCN due to overfishing, particularly in the international waters off the coast of Portugal where they migrate to breed in the June/July months. Some other historic English names for the blue marlin are  Cuban black marlin,  ocean gar, and ocean guard.
