Length-at-maturity has been determined in a few studies examiningmale and female gonads, and while these studies have beenrestricted by the lack of small fish in the samples, females tend tomature at a larger size than males. Length at first maturity was estimatedto be approximately 860 mm and 1010 mm total length (TL)for males and females, respectively (Hogarth, 1976). Similarly, malewahoo from the Caribbean were estimated to mature at some sizesmaller than 935 mm FL, while the length at which 50% of femalesare mature (L50) was 1020 mm FL (Brown-Peterson et al., 2000).Also from the western-central Atlantic Ocean, a recent estimateof L50 for female wahoo was 925 mm FL, and it was suggested thatmost fish become sexually mature during their first over-winteringseason, and at an age of <1 year old (Jenkins and McBride, 2009).Unfortunately no estimate of size-at-maturity for male fish wasobtained by this most recent study.
