The mud crab, Scylla spp., is a common estuarine crustacean found along the coast of Papua New Guinea. Two species were studied in the Labu estuary near Lae: S. serrala and S. paramamosain, S. serrata becomes sexually mature at a smaller size (10-cm carapace width) than S. paramamosain (12 cm). Both the size of S. serrata at initial reproduction and maximum size of females are smaller than in populations studied at higher latitudes such as Queensland, Australia and South Africa. Reproduction occurs continuously throughout the year in the S. serrala population. The percentage of reproductive females was slightly larger during the change of seasons in March/April and September/October. The parasitic gill barnacle, Octolasmis cor, did not inhibit reproductive development. There was no variation in the gonadal somatic index associated with lunar periodicity.
