(Costa Rica, Guatemala, Peru Longline)
There are no coordinated international laws to reduce bycatch in the mahi mahi fishery, and international longline fleets are contributing heavily to the long-term decline of some threatened or endangered species. As a result, mahi mahi caught by Peruvian, Costa Rican and Guatemalan longline fleets is rated as "Avoid."
Mahi mahi is primarily available as fresh or frozen fillets. Most mahi mahi found in the US market is imported.
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 hook-and-line 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-and-line, 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.
