Marlin, Blue – Imported Pacific, Longline
Blue Marlin is a large pelagic species, found in tropical and temperate waters worldwide. Blue Marlin mature early, produce many eggs, and grow fast, reaching sizes up to 450 cm and 900 kg. There is some uncertainty about the abundance level of Blue Marlin in the Pacific Ocean, but fishing is occurring at a sustainable level.
This species is primarily captured with pelagic longlines, which cause minimal damage to ocean habitats, but result in bycatch of sea turtles, seabirds, and sharks. Additionally, the fisheries that catch blue marlin in the North Pacific also catch Pacific bluefin tuna, a species of critical conservation concern. Management of the international fisheries that capture Blue Marlin in the Pacific is considered ineffective.
Consumers should also note that illegally-sold Atlantic Blue Marlin reaches the U.S. Market.
