Artificial induction of milkfish spawning has been achieved in the Philippines, Taiwan, and Hawaii. The injection of exogenous gonadotropins has been used traditionally to induce the final maturation of captive female fish at the completion of vitellogenesis. This paper reports trials with a new LHRH-A cholesterol pellet, prepared at the Oceanic Institute in Hawaii to determine its ability to induce the maturation and spawning of captive milkfish.
