The shortbill spearfish is a species of marlin that lives in the tropical and temperate waters of the Indian and Pacific oceans. It is a highly migratory species, and is usually found close to the surface of the water.
The shortbill spearfish has a dark black band extends across the top of the fish with a silver-white colour below. The dorsal and ventral fins are almost black and the anal fins are a white colour. The inner surfaces of the tail and the pectoral fins are black and the outer surface is white. This fish has a mild flavour and is commonly served grilled.
Although some stray individuals are found in the Atlantic Ocean, this species is believed to have its spawning grounds and principal populations only in the Pacific and Indian Oceans. Spawning is believed to occur mainly during the winter months, especially in warm offshore currents with surface temperature of about 25°C.
This fishery uses a longline to catch a variety of pelagic fish on the high seas such as tuna and swordfish. A deep-set longline is used to primarily target tuna and a shallow-set longline is used to target swordfish or mixed species including bigeye, Albacore and yellowfin tuna. Baited hooks are attached to a line that floats in the ocean using buoys and flagpoles.
This fishery uses a variety of artisanal hook-and-line methods to catch coastal pelagic fish such as tuna, marlin, swordfish, mahi mahi, wahoo (ono) and others. A pole and line with live bait scattered into the water is used to catch feeding skipjack tuna. Trolling with lures and lines, and handlines with lures, lines and bait bags are used to target larger fish such as bigeye tuna, swordfish, mahi mahi and wahoo.
This fishery uses rods and reels to catch six species of snapper and one species of grouper that are called “bottomfish.”
This fishery uses a variety of artisanal methods to catch reef fish, including handlines, and pole and lines. Catch rates are low, usually only a few pounds per hour with little bycatch (discards). These small-scale fishing methods are similar to those traditionally used by native Hawaiians.
Spearfishing has been used throughout the world for millennia. Early civilizations were familiar with the custom of spearing fish from rivers and streams using sharpened sticks, and it is still practiced today in many areas of the world. Today, spearfishing may be done using compressed gas pneumatic powered spearguns, or spearguns and slings while free-diving, snorkelling or scuba diving; although, spearfishing while scuba diving is illegal in some countries.
