Skip the middle man. Support the U.S. economy. Buy fresh & direct from Marshallberg Farm.

Support Sustainable U.S. Aquaculture


With over 80% of caviar distributed in the USA being imported from Chinese farms, family-operated Marshallberg Farm aims to break the mold and sustainably produce Osetra caviar right here in the USA.

Using new, state-of-the-art R.A.S. (recirculating aquaculture system) technology, we are able to raise our sturgeon without being dependent on an outside body of water (lake, river, pond, etc.). We recycle over 95% of our water, responsibly containing our waste instead of releasing it into the environment. We are the only full RAS sturgeon farm in the USA, ranked a “Best Choice” for sustainability by the Monterey Bay Aquarium Seafood Watch (
By using a recirculating system, we are not at the mercy of outside pollutants, and maintain full control of our water quality. This system is more like a water treatment plant than a fish farm. We filter about 1 million gallons a day, giving us the highest filtration possible for our fish.

High filtration = clean water = happy fish = better caviar!


Unlike imports, we do not use borax or any other chemicals in our caviar production. We follow strict U.S. regulations for environmental, health and food safety.
