"In spite of the readiness with which the Japanese oyster (Ostrea gigas Thunberg} lives and grows in Canadian Pacific waters, its reproduction here has been a matter of great irregularity and apparent caprice. During the early years of its cultivation in Ladysmith harbour spawning occurred only occasionally and very few individuals reached the spatting stage. C. R. Elsey showed that it was possible to induce spawning of large numbers of Japanese oysters by stimulation with the ripe gonads of a small number of individuals and by movement. Largely as a result of his work, considerable spawning has occurred every summer in recent years. Heavy spatting, however, has taken place in only two seasons, namely 1932 and 1936. In other years large numbers of larvae have appeared in the plankton of the bay for longer or shorter periods but very few have lived to become spat"--Page [1].
