Some problems exist with this species' status or catch methods, or information is insufficient for evaluating. Mahimahi – U.S., Longline These fish contain levels of mercury or PCBs that may pose a health risk to adults and children.

Mahimahi produce many eggs, grow quickly, and reach sexual maturity at a young age, making them resilient to fishing pressure. No formal population assessments have been completed in any region, so their current population sizes are not known.

Mahimahi are caught by a variety of fishing gears including longlines. This type of fishing also captures a number of other species, including sea turtles, marine mammals, seabirds and sharks. In the U.S. management measures are in place to reduce catches of these species.
