Hog Island Oyster Co. has been growing shellfish for 40 years. Like most shellfish farms, Hog Island mainly sells the large Pacific oyster, although also produces small quantities of other species, such as Kumamotos, Virginica, European Flats, and most recently, Olympia. The Olympia oyster, or “Oly” is the only oyster native to the west coast of North America, and persists in very low numbers in certain estuaries and bays they were once abundant. In an effort to reverse their decline in Tomales Bay, Hog Island is utilizing aquaculture-assisted restoration to raise Olys for both market and restorative value. Hog Island is also working to help researchers better understand the relationship between oyster aquaculture activity and eel grass habitat.
