  Se describe el estado de madurez gonadal de algunas especies ícticas presentes en la Bahía de Cartagena. Se recolectaron 1431 individuos pertenecientes a 79 especies, durante el período de 10 meses, registrando 11 nuevas especies para el área de estudio. Se encontró una proporción hembra-macho de 1,4:1, 270 juveniles y 68 indiferenciados. De acuerdo a la distribución porcentual, se hizo una relación con respecto a la proporción hembra-macho de las 18 especies más significativas y representadas por: Haemulon bonariense (17,93%) 1,09:1, 2 juveniles y 1 indiferenciado; Elops saurus (14,1%) 1:4,6 y 162 juveniles; Scomberomorus brasiliensis (9,77%) 1:2,1 y 2 juveniles; Cathorops spixii (7,19%) 6,91:1, 4 juveniles y 4 indiferenciados; Archosargus rhomboidalis (4,54%) 1:1,37; Chloroscombrus chrysurus (4,12%) 1:1,9, 2 juveniles y 17 indiferenciados; Bagre marinus (3,42%) 3:1; Oligoplites saurus (2,72%) 2,5:1, 2 juveniles y 1 diferenciado; Caranx latus (2,3%) 1 hembra y 32 juveniles; Mugil tricodon (2,16%) 8,3:1, 1 juvenil y 1 indiferenciado; Opisthonema oglinum (2,02%) 1,87:1; Mugil liza (1,61%) 1,4:1 y un juvenil; Centropomus undecimalis (1,61%) 1:1,5 y 2 juveniles; Ariopsis bonillai (1,4%) 4:1, 1 juvenil y 1 indiferenciado; Gerres cinereus (1,33%) 3,4:1, 2 juveniles y 2 indiferenciados; Scomberomorus cavalla (1,33%) 1:1 y 1 juvenil; Caranx hippos (1,19%) 17 juveniles, Trichiurus lepturus (1,12%) 6,5:1 y 1 indiferenciado.
