To investigate the reproductive biology of Callinectes ornatus gonadal and moulting cycles were studied over two consecutive years in the Ubatuba region. Six stages of gonadal development were detected in females and four in males. Observations on the number of ovigerous females, on the moulting stages of males and females, and on the percentage of individuals exhibiting mature gonads reveal a continuous reproductive cycle, the stages of which progress at different rates. These data support the hypothesis that C. ornatus shows staggered spawning, with possibly more than one annual reproductive period. A pause in growth before the terminal moult may occur in this species.

L'evolution des gonades et des cycles de mues a ete etudiee chez Callinectes ornatus, pendant deux ans, dans la region de Ubatuba, Bresil, afin de mieux connaitre la biologie de la reproduction de cette espece. Six stades dans le developpement des gonades ont ete observes chez les femelles et quatre chez les males. L'observation du nombre de femelles ovigeres, des stades de mue des males et des femelles et du pourcentage d'individus sexuellement murs, montre que la reproduction a lieu toute l'annee. Ceci appuie l'hypothese selon laquelle les Portunidae femelles ont une ponte echelonnee, avec probablement plus d'une periode reproductive dans l'annee. Une pause de croissance avant la mue terminale peut exister.
