Changes in the seasonal development of the gonads in Acanthopagrus latus and A. cuvieri over an annual reproductive cycle are described. There is one major spawning period from January to March. Hermaphrodite A. latus and A. cuvieri constituted 5.8% and 5.7% of the total sample respectively. The histological changes in the ovary, testis and ovo‐testis in both species are described. Fecundity estimates for A. latus , 27.5–31.8 cm, ranged from 1 362 137 to 2 152 993, and estimates for A. cuvieri , 47.1–63.5 cm, ranged from 308 273 to 1 693 365.
