Biology & Habitat

Appearance

Striped marlin are large, oceanic fish with long, round bills, small teeth, and a tall dorsal fin. Their bodies are dark blue-black on the top and fade to a silvery white on the bottom. They have rows of blue colored stripes made up of smaller round dots or narrow bands.

Biology

Striped marlin are smaller than other marlin species, but can reach a length of 12 feet and weigh more than 450 pounds. Spawning occurs in the central Pacific and off central Mexico. Juvenile fish move east toward the coast of Mexico, where they are found in high abundance around the tip of the Baja Peninsula. Striped marlin are opportunistic feeders of fish including mackerel, sardine, and anchovy.

Where They Live

Range Striped marlin live throughout tropical and sub-tropical waters of the Pacific and Indian Oceans. Habitat Striped marlin prefer water temperatures of 20–25˚ C. Acoustic telemetry studies indicate that they spend 86 percent of their time in the surface layer above the thermocline (a layer above and below which the water is at different temperatures).

How to Buy & Source

Availability

Striped marlin is caught year-round, but the majority is caught between November and June.

Source

U.S. wild-caught from waters around Hawaii, other U.S. Pacific Islands, and the high seas.

Commercial Fishery & Harvest

Commercial fishery: In 2024, commercial landings of Pacific striped marlin totaled 1.3 million pounds and were valued at $1 million, according to the NOAA Fisheries commercial fishing landings database . The Billfish Conservation Act , along with existing billfish regulations, prohibits the sale and commercial possession of billfish and billfish products. However, those that are caught in Hawaii and the Pacific Insular Areas (which includes American Samoa, Guam, and the Northern Mariana Islands) are exempt and can be sold. Prohibitions on the sale of striped marlin on the U.S. West Coast provide a strong disincentive for commercial fishermen to catch striped marlin.
