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. Mahimahi are typically caught using pelagic (surface) longline gear, which has a minimal impact on bottom habitat.
