Wahoo
Fast tropical game fish with blue bars

- Diet is 84% native fish
- Known as ono in Hawaii
- Females outnumber males in most areas
- Hosts harmless stomach worm parasite
What it is
This fish has an elongated body with an iridescent blue back and silvery sides marked by irregular vertical blue bars. These colours fade quickly after death. It possesses a large mouth with razor-sharp teeth that appear sharper than those of king or Spanish mackerel. Adults can reach lengths of nearly three metres and weigh over eighty kilograms. The species grows rapidly and is built for speed in open water.
Where it lives
Wahoo inhabit tropical and subtropical waters across the Atlantic, Pacific, and Indian Oceans. Genetic studies suggest two weakly distinct stocks exist in the Atlantic and Indo-Pacific regions, with significant migration and gene flow between them. They are found worldwide in these warm seas, often near deep-water structures or floating objects that attract marine life.
How it lives
Their diet consists mainly of other fish and squid, with small amounts of crustaceans. Stomach analyses in the Pacific show a high proportion of native fish. They usually live alone or in small groups of two or three, though larger schools of over one hundred may form in suitable conditions. Most individuals host a giant stomach worm parasite, which does not seem to harm them.
Breeding and life cycle
The species produces buoyant eggs, and the resulting larvae live in the open ocean. The population gender ratio favours females, a trait common in many pelagic marine species. Ratios vary by location, ranging from nearly equal in Puerto Rico to more than three females per male in North Carolina. Specific spawning seasons are not detailed in the provided text.
Fish and people
Anglers prize wahoo for their speed and fighting ability, often catching them near oil platforms using live bait. The flesh is white or grey, dense, and compared to mackerel in taste. It is a premium food fish in Hawaii, Bermuda, and the Caribbean, where artisanal fishermen target them by trolling. Commercial fisheries also take them as bycatch in tuna and billfish operations.
Status and threats
The species is not considered overfished overall, though local populations may face pressure from heavy fishing. They are less vulnerable to industrial methods than tightly schooling tuna but are regularly caught as bycatch in longline and purse seine fisheries. A management plan for the Atlantic was issued in 2003 to help regulate the fishery.
