About the Species
U.S. wild-caught mahimahi is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.
Above target population levels.
At recommended levels.
Fishing gear used to catch mahimahi rarely contacts the ocean floor and has minimal impacts on habitat.
Regulations are in place to minimize bycatch.
- Scientists assume populations are abundant because they are highly productive and widely distributed throughout tropical/subtropical oceans.
- Scientists conducted an exploratory assessment of mahimahi in 2000 and determined that the stock was not overfished, but they have not conducted a formal stock assessment.
- Atlantic mahimahi is not subject to overfishing.
- Brightly colored back is an electric greenish blue, lower body is gold or sparkling silver, and sides have a mixture of dark and light spots.
- Bright pattern fades almost immediately after mahimahi is harvested.
- Adult males have a square head.
- Females have a rounded head.
- Distinguished from the pompano dolphin by its 55 to 66 dorsal fin rays and a very wide, square tooth patch on the tongue.
- Atlantic mahimahi grow up to almost 7 feet and 88 pounds.
- They live up to 5 years.
- They are capable of reproducing at 4 to 5 months old.
- Believed to spawn every 2 to 3 days during the spawning season, releasing between 33,000 and 66,000 eggs each time.
- In the Atlantic, spawn under patches of floating brown algae called Sargassum.
- Mahimahi are top predators that feed in surface water during the day.
- They eat a wide variety of species, including small pelagic fish, juvenile tuna, invertebrates, billfish, jacks, pompano, and pelagic larvae of nearshore, bottom-living species.
- Predators include large tuna, marine mammals, marlin, sailfish, and swordfish.
Where They Live
- Mahimahi are found in the Atlantic, Gulf of Mexico, and Caribbean, and are caught from Massachusetts to Texas.
- About one-third of U.S. commercial harvest of mahimahi comes from the Atlantic, Gulf of Mexico, and Caribbean. The rest comes from the Pacific, mainly Hawaii.
- NOAA Fisheries and the South Atlantic Fishery Management Council (in cooperation with the Mid-Atlantic and New England Fishery Management Councils) manage the Atlantic stock of Mahimahi.
- Managed under the Fishery Management Plan for the Dolphin and Wahoo Fishery of the Atlantic:
- Permits are required to sell mahimahi.
- Minimum size limit for mahimahi caught off the coasts of Georgia, Florida, and South Carolina to protect smaller fish.
