The Southern kingfish Menticirrhus americanus is distributed along of Atlantic West Coast. Such as others Sciaenidae the Southern kingfish has been considered potential to marine and estuarine fish culture. Part of successful in captivity is reproduction, and then the study aimed evaluates the M. americanus reproduction in captivity using hCG. The females were induced with 300 IU hCG.kg-1 BW. The spawning successful was obtained in 60% induced. The latency period was 38.1 ± 3.4h, the eggs diameter was 730 ± 0.06 µm, segmentation and hatching rate were 63.8 ± 14.5% e 43.3 ± 10.7%, respectively. The fertility was estimated in 137,291 ± 136,949 ovos.kg-1. The results showed the Southern kingfish is sensitive to hCG and it is possible to obtain viable larvae through artificial reproduction.Downloads
