Mahi Mahi, Longline, U.S.

U.S. longline-caught mahi mahi is subject to strict regulations to limit the accidental catch of sea turtles and other species and therefore receives a "Good Alternative" rating.

Consumer Note

Mahi mahi is primarily available as fresh or frozen fillets. Most mahi mahi found in the U.S. market is imported.

Summary

Mahi mahi is a beautiful and acrobatic fish, popular with sport anglers. It grows and matures quickly possibly allowing it to withstand heavy fishing pressure. However, scientists still know very little about the overall population size and this lack of data is cause for concern.

Mahi mahi is caught primarily using longlines and handline gear. There is considerable concern about bycatch from longlining as sea turtles, seabirds, sharks and marine mammals get caught or entangled in the gear, often resulting in injury or death for these animals. Fisheries that employ troll, pole, or handline gear have little to no bycatch and therefore are typically a low conservation concern. However, well-managed longline fisheries using a suite of measures to reduce incidental catch can also be more sustainable.
