Mostly eats fish, but also squid. Wahoo are found in solitary or forming loose aggregations, they are possibly migratory, however little is know about their migration patterns. This species is a fast growing, early maturing species that usually reach 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 summer between October and February, where females display batch spawning and spawn every 2 – 3 days. This species is highly fecund with larger females produce more eggs than smaller females, fecundity ranges between 0.44 and 1.67 million eggs per individual. Maximum average age is estimated at 5 – 6 years,3 but can reach a maximum age of 9 years.4


Caught primarily by surface trolling.
