The Science

THE SCIENCE

Ferocious predators: this fish is thought to be able to eat fish larger than itself by using its sharp, serrated teeth to tear prey into bite-sized pieces. [1]

Taxonomic description 

  • Has a streamlined body with metallic blue on top and pale blue on underside, 25-30 vertical stripes running from head to tail. [1]
  • Averages 1-1.6m (3.3-5.4 ft) in length, but can grow up to 2.4m (8 feet) and weigh up to 71.7 kg (158 lbs). [1]
  • Has a long snout and large mouth with triangular, compressed, serrated teeth that allows it to capture and tear chunks out of its prey. [1]

Distribution 

  • Found in tropical and subtropical waters worldwide (Atlantic, Indian, and Pacific Oceans), and its range may expand to higher latitudes during the warmer season. [1,2]

Life history 

  • Reproduction occurs year-round in tropical waters and during summer months at higher latitudes. [1]
  • Females will release thousands of eggs to be externally fertilized by males, and spawning occurs multiple times per year. [1] 

Habitat

  • Pelagic, hunts its prey with terrifying bursts of speed. [3]
  • Feeds mainly on fish, including frigate mackerel, butterfish, porcupine fish, and round herring. [1]

 

The Fishery

Seasonal availability 

  • Caught year-round. [4]

Regulatory and managing authority 

  • Along the Pacific West Coast, the fishery is overseen by NOAA fisheries and, as established by the Magnuson-Stevens Act, the Pacific Fishery Management Council  through the West Coast Highly Migratory Species Fisheries Management Plan. [4,5]
  • As established by the Marine Life Management Act, the California Department of Fish and Wildlife (CDFW) collects data on this fishery. [12]

Gear type 

  • Caught incidentally in troll, longline, and hook and line fisheries, such as those targeting tuna. [4]

Status of the fishery 

  • The fishing rate and population status of Pacific wahoo are not well known as scientists do not formally assess Pacific wahoo populations. [4]
  • Regulations and improved gear reduce bycatch and incidental captures. [4]

Potential ecosystem impacts

  • There are few impacts on the seafloor as the gear used in this fishery do not typically come into contact with the seafloor. Bycatch may sometimes be an issue, but it is relatively small as there is no directed fishery for Pacific wahoo. [1]

 

The Seafood

THE SEAFOOD

Wahoo can be cooked in a similar style to tuna, and takes very well to marinades. [6]

Edible portions

  • Found as fillets, steaks, and whole. [4]

Description of meat

  • Raw wahoo meat is a pale-pink, with less red than mackerel. Turns white when cookied and has a firm, lean texture and large, circular flake.[6]
  • When cooked, some say it tastes mild or like lean tuna. [6]

Culinary uses

  • This fish can be broiled, grilled, poached, sauted or smoked. It has a low fat content, so the meat can dry out when cooking. [6]
  • For a recipe for grilled wahoo with mango salsa, visit Local I'a. [7]
  • For a Malaysian fish curry recipe that can be substituted with wahoo, visit Kuali. [13]
