Species is relatively abundant, and fishing methods cause little damage to habitat and other wildlife.
Wahoo – Pacific Ocean These fish contain levels of mercury or PCBs that may pose a health risk to adults and children.

Wahoo are a fast growing, highly fecund species of fish found worldwide throughout tropical and warm temperate seas.

Wahoo are not commercially targeted but are caught in longline, purse seine and troll fisheries targeting other species such as tuna and swordfish.

A lack of data has hampered the completion of a comprehensive population assessment throughout the Pacific, so the status of their population in this region is unknown, although evidence from Taiwan indicates the population is not at a risk of over-exploitation.

Pelagic longline, purse seine and troll fishing gears have a limited impact on bottom habitat, but pelagic longlines can catch high numbers of seabirds, sea turtles, and sharks. Some fisheries, such as the Hawaiian shallow-water pelagic longline, have instituted comprehensive mitigation measures to reduce bycatch.
