The addition of hydrogen peroxide to alkaline seawater provides an inexpensive, simple, and reliable method for the control and synchronous induction of broadcast spawning in males and females of certain bivalve and gastropod molluscs. Species successfully induced by this method thus far include:abalones ( Haliotis rufescens, H. corrugata , and H. fulgens ), mussels ( Mytilus edulis and M. californianus ), purple‐hinged rock scallop ( Hinnites giganteus ) and the mangrove oyster ( Crassostrea rhizophora ). Enzymological and physiological studies indicate that spawning may result from a peroxide‐induced stimulation of the endogenous enzymatic synthesis of potent hormone‐like prostaglandin molecules. Peroxide‐stimulated prostaglandin synthetase also has been found in reproductive tissues of certain crabs and fishes, thus indicating potential applicability of this method for the control of reproduction in higher species. However, internally fertilized gastropods, such as the queen conch ( Strombus gigas ), show no induction of reproductive behavior or egg‐laying (after mating) upon exposure to H 2 o 2 .
