| Abstract: | Aspects of the reproductive biology of Pomadasys argenteus, Otolithes argenteus and Pampus argenteus are described. Maturation of the gonads is divided into 8 arbitrary stages, and the distribution of the stages in an annual cycle is reported. In Pomadasys argenteus there is a major spawning period from February to April and another minor one in October. In Otolithes argenteus there is one distinct spawning period from January to April. The spawning season of Pampus argenteus extends from March to August. The histology of the gonads and the distribution of oocytes of different diameters in the ovaries of the 3 fish species are described. The distribution of oocyte diameters in the ovary of Pampus argenteus is polymodal and characteristic of serial spawners, whereas the distribution of oocyte diameters in Pomadasys argenteus and Otolithes argenteus corroborate the finding that these fish are single spawners. The estimated potential fecundity for Pomadasys argenteus ranged from 6 25 848 to 2 424 846, for Otolithes argenteus from 53 676 to 7 163 954 and for Pampus argenteus from 765 675 to 2 537 774. |
