About Us

Catalina Sea Ranch (CSR) is the first federally permitted and operational aquaculture facility located 6 miles offshore in U.S. Federal waters. Currently selling to the Southern California market since summer of 2018, CSR is planning to expand the initial 100 acres to over 1,000 acres by documenting no negative environmental or social impact. Launching operations with low-risk, highly profitable mussels, expansion plans will include cultivation of additional sustainable mollusk and seaweed crops. Visit our press page for recent features in Washington Post, Quartz Media, and USA Today.

CSR has a robust Research and Development program, and has been awarded over $1M in grant funding from the US Department of Energy, NOAA, and USDA for projects including: selective breeding, cryopreservation, and kelp as biofuel. CSR’s NOMAD buoy is equipped with technologies for transmitting real-time data for remotely monitoring environmental data.

Our Mission

Sustainability is at the heart of our mission. Mussels and shellfish are arguably the most sustainable animal proteins on the planet. Unlike terrestrial crops, they require no feed, fresh water or fertilizer, as they filter the oceans.

Despite having one of the longest coastlines on a global scale, the U.S. imports 91% of its seafood, and lags far behind in worldwide aquaculture development. Collapsing fisheries and in-state permitting difficulties call for a new solution to feed the growing population and demand for protein. Offshore, sustainable aquaculture can meet this need, while protecting the health of our fragile ecosystem with an IMTA polyculture approach.

As the first and only offshore facility in U.S. Federal waters, CSR is at the leading edge of the “Blue Revolution”, and intends to set a precedent for clean, regenerative ocean farming by utilizing the latest advances in science and technology.
