Mostly eats fish, but also squid. Wahoo are solitary or form loose aggregations. They are possibly migratory, however little is know about their migration patterns. This species is fast growing and usually reaches maturity within the first year of life. Off the Atlantic coast of Florida and the Bahamas, the age and length at which 50% of female wahoo reach maturity was 0.64 years, and 92.5 cm FL respectively,1 while female wahoo off eastern Australia reach a length at 50% maturity at 104.6 cm FL.2 The spawning season varies regionally, in eastern Australia spawning occurs in spring to summer between October and February, where females display batch spawning and spawn every 2–3 days. This species is highly fecund producing between 0.44 and 1.67 million eggs per individual. Larger females produce more eggs than smaller females. Estimated average age is 5–6 years,3 but can reach a maximum age of 9 years.4
Caught primarily by surface trolling.
