Oysters from high yielding families are first conditioned in a flow-through system where elevated water temperature and algal food supply encourage egg and sperm production. Once acceptable reproductive condition is reached, animals are strip-spawned and sperm from a single male is used to fertilize eggs from a single female. Fertilized eggs develop into swimming larvae within 24 hours and remain free-swimming for approximately 2 weeks. Larvae are fed on algae and grow from the D-larval stage to the eyed larval stage. Family-specific larval rearing tanks are required in order to keep pedigreed families separate. Our hatchery can hold up to 60 separate family groups. After approximately two weeks post-spawn, eyed larvae are retained on a 240 μm sieve and exposed to epinephrine, inducing metamorphosis from swimming veliger larvae to sessile juvenile “spat”. The spat are then moved to our upweller nursery system.
