The Blue Marlin, Makaira nigicans, is the largest of the Atlantic marlins and is one of the biggest fish in the world.
They can reach lengths up to 14 feet and weigh almost 2000 pounds. An average size would be in the range of 10-11 feet. All of the trophy size Blue Marlins are females, males rarely exceed 300 pounds in size.
Native to the tropical and temperate waters of the Atlantic, Pacific, and Indian Oceans, blue marlins are among the most recognizable of all fish. They are cobalt-blue on top and silvery-white below, with a pronounced dorsal fin and a long, lethal spear-shaped upper jaw.
They spend most of their lives in deep water. Their diet consists mainly of mackerel and tuna, but will also dive deep to eat squid. They are among the fastest fish in the ocean, and use their spears to slash through dense schools, returning to eat their stunned and wounded victims.
Known for putting up a tremendous fight and aerial show when hooked, they are highly prized by sport fisherman. Fisherman generally target these fish by trolling natural baits with and without skirts.
Dredges and other forms of teasers are often deployed in the boat’s wake to help raise fish to the surface. Like other billfish, blue marlin will use their bill to stun the baits and then come back to eat thus many anglers use outriggers to provide a “drop back” and more natural presentation.
