Abstract
An extract of radial nerves of the sea urchin. Strongylocentrotus purpuratus, induces spawning within 1 minute in this species as well as in other echinoids, but a delayed spawning in several asteroid species. The concentration of the spawn-inducing factor in the radial nerves fluctuates annually correlated with the reproductive season of this species along the coast of southern California.Keywords
