Wahoo Fast Facts

• Wahoo are related to mackerels and are members of the fish family Scombridae.

• Wahoo live in tropical and subtropical waters worldwide. During the summer, they may migrate into temperate waters.

• According to the International Game Fish Association, the official record (http://www.igfa.org) for the largest wahoo caught on hook and line is 158.5 lb (71.9 kg). However, uncertified reports indicate wahoo may grow as large as 200 lb (91 kg) or more.

• Wahoo tend to be solitary, but they are occasionally found in small, loose schools.

• Wahoo is a prized game fish due to its speed, fighting qualities, and excellent flavor.

• Wahoo are among the fastest pelagic species (reaching speeds up to 60 mph) and are capable of capturing a wide range of prey, including various fishes and squid.

• Wahoo are thought to be relatively fast growing. In one study, a wahoo that was tagged, released, and recovered ten months later had grown around 22 pounds in less than a year-from 11 lb (5 kg) to 33 lb (15 kg).

• The giant stomach worm (Hirudinella ventricosa) is commonly found in wahoo stomachs, but the worm does not affect the portion of the fish eaten by humans.

• Wahoo have been included in the FWC-FWRI Mercury Program, which investigates total mercury levels in the muscle tissue of various Florida fishes. The Florida Department of Health (http://www.doh.state.fl.us/) has issued a health advisory for wahoo in the Florida Keys and Florida Bay regions.

• Wahoo are currently the topic of much scientific research in Florida. Scientists at the Fish and Wildlife Research Institute are studying wahoo biology. Scientists at Florida Atlantic University are conducting a genetic study to investigate the relationship between individual wahoo from different parts of the world.

• A recently approved management plan, developed by the South Atlantic Fishery Management Council (http://www.safmc.net) in conjunction with the Mid-Atlantic and New England councils, will set limits on commercial and recreational dolphin and wahoo catches in federal waters along the entire Atlantic coast.
