The project, funded by a grant from the Anthropocene Institute and supported by California Sea Grant, is the first attempt to support native oyster restoration using aquaculture in California. California Sea Grant Extension Specialist Luke Gardner, who is based at the Moss Landing Marine Laboratories (MLML) in Monterey Bay, worked with project leader Kerstin Wasson, Elkhorn Slough Reserve’s Research Coordinator, and colleagues at MLML to help spawn and raise the juvenile oysters in MLML’s new aquaculture facility…
