The striped marlin, Tetrapturus audax, is a species of marlin Found in tropical and warm temperate waters of the Indian and Pacific oceans, the striped marlin is pelagic.
The most distinguishing characteristic is its high, pointed first dorsal fin, which normally equals or exceeds the greatest body depth. Even in the largest specimens this fin is at least equal to 90 percent of the body depth. Like the dorsal fin, the anal and pectoral fins are pointed. They are also flat and movable and can easily be folded flush against the sides, even after death. The sides are very compressed. The lateral line is straight, single and clearly visible. The back is steely blue fading to bluish silver on the upper flanks and white below the lateral line. There are a number of iridescent blue spots on the fins and pale blue or lavender vertical stripes on the sides.
It is highly predatory, feeding extensively on pilchards, anchovies, mackerel, sardines, flying fish, squid, and whatever is abundant. It is well known for its fighting ability and has the reputation of spending more time in the air than in the water after it is hooked. In addition to long runs and tail walks, it will “greyhound” across the surface, making up to a dozen or more long, graceful leaps. Fishing methods include trolling whole fish, strip baits, or lures; also live bait fishing.
