Abstract This review concerns itself with two aspects of reproductive biology: commencement of gametogenesis and spawning. The activation of gametogenesis followed by gonadal growth, with a subsequent release of gametes. The gamete formation-spawning cycle varies in duration from weekly to yearly periods depending upon the species and geographical origin. The importance of exogenous factors is discussed. Among those exogenous factors which can be demonstrated to affect the gamete formation-spawning cycle are food, salinity, light and temperature. Gonad growth constitutes a more significant fraction of the entire reproductive cycle than does spawning and gametogenesis. The time during which gametes are released occupies a small fraction of the entire reproductive cycle. Since spawning is such a dramatic act, it has been described in detail for many species. Numerous investigators have shown interest in the factors and relationships which work to insure synchronization of spawning. These studies are fully discussed. Some considerations of larval ecology in relation to parental reproductive patterns are given. Finally, the possible mechanism involved in coordination of reproduction is presented.
