Abstract

A literature review reveals that reproductive seasonality of less than 1% of South Africa's inshore marine invertebrates has been studied. Approximately 95% of studies have been on large, long-lived, gonochoristic, iteroparous species, and nearly 50% on molluscs. There is only a weak relationship between biogeographic region and timing of reproduction, Nevertheless, a relatively large proportion of west coast species studied breed in winter, whereas south coast species tend to have breeding peaks in spring/summer, although many nearly always have mature gametes and probably reproduce year-round. East coast species are mainly continuous or summer breeders, The factors that control gametogenesis and trigger spawning are largely unresolved, although temperature and food are thought to be important in many species.
