Grassy Bar Oyster Company

Grassy Bar Oyster Company Grassy Bar is an oyster bed on Morro Bay estuary, cared for by the Trevelyan family of Cayucos.

I am a marine ecologist with 30 years experience working in sustainable, environmentally sound molluscan aquaculture. Grassy Bar was founded in 2009 when I "bought the farm" and got beached on the back bay with a bevy of bivalves. Much to my relief my son Charles came to help me, and to share my passion to coax our beds to flourish with the succulent shellfish.

Grassy Bar Oyster Company is dedicated to ensuring our farming practices harmonize with the health of Morro Bay.

That's why we collaborate with the Morro Bay National Estuary Program (MBNEP, ) and other colleagues to help monitor and preserve our precious ecosystem. Dr. Nathan Churches, the GBOC science lead, recently discussed shellfish farming in the bay at the MBNEP Science Explorations night at Cuesta College. You can find some of our collaborative work on Page 11 of the 2026 State of the Bay Report produced by the MBNEP.

For Grassy Bar, the health of the bay is the health of the business!

Every oyster has a story.

From tiny seed in our nursery, to months growing in the cold, productive waters of Morro Bay, to being harvested by hand and shucked just steps from the bay — every oyster we serve carries the care of our crew and the character of this place.

We believe great seafood should be fresh, local, and connected to the people who grow it.

Thanks for supporting our small farm and letting us share a little piece of Morro Bay with you. 🦪
