In the rolling countryside of North Carolina, Marshallberg Farm is redefining what caviar can be—and where it comes from. While over 80% of caviar consumed in the U.S. is imported from Chinese farms, this family-owned operation is producing world-class Osetra caviar right here at home. Using state-of-the-art recirculating aquaculture systems (RAS), Marshallberg raises Russian sturgeon in crystal-clear, filtered water that’s recycled and purified over 95% of the time—ensuring pristine conditions, zero environmental discharge, and unmatched product purity. The result is caviar that’s fresh, buttery, and free from additives like borax or preservatives—just pure, hand-harvested Osetra pearls that rival the finest imports. Rated a “Best Choice” for sustainability by the Monterey Bay Aquarium’s Seafood Watch, Marshallberg stands as America’s most advanced and responsible sturgeon farm. When you choose their caviar, you’re not just savoring a delicacy—you’re supporting sustainable U.S. aquaculture and a new era of American craftsmanship in luxury seafood.
Russian sturgeon cultivated in harmony with nature
Located in the heart of North Carolina’s coastal plains, Marshallberg Farm draws on the region’s pure freshwater sources and temperate climate to cultivate Russian sturgeon in harmony with nature. The farm sits near the small town of Lenoir, just inland from the Atlantic, where the balance of clean well water and advanced filtration technology creates ideal growing conditions for these ancient fish. Through a state-of-the-art recirculating aquaculture system (RAS), more than 95% of the water is continuously purified and reused, eliminating discharge to surrounding waterways. This closed-loop environment mirrors the flow of a pristine river system—oxygen-rich, stable, and meticulously controlled for purity. Far from industrial ports or pollution sources, Marshallberg’s location embodies precision and environmental stewardship, showcasing how inland aquaculture can produce ocean-quality seafood while protecting the watersheds of the American South.
Patience and precision
Marshallberg Farm is the vision of the Marshall family—American pioneers bringing the legacy of Russian Osetra caviar into a new era of sustainability. Founded by brothers Ivars and Tryggvi, and guided by a shared belief that the U.S. could produce caviar to rival the best in the world, the family built their dream from the ground up on North Carolina soil. Their team of aquaculture engineers and fish biologists manage every stage of production—from hatch to harvest—within fully recirculating aquaculture systems, ensuring complete control over water quality and fish welfare. It’s meticulous work that blends Old World tradition with American ingenuity. Every tin of caviar represents years of patience, precision, and respect for a species once pushed to the brink of extinction. For Marshallberg’s team, this isn’t just farming—it’s conservation in action, and proof that the world’s finest caviar can be produced sustainably, right here in the USA.

Award-Winning Ostera Caviar
The Russian sturgeon is a living fossil—a prehistoric species that has swum the Earth’s rivers and seas for over 200 million years. These ancient fish, once abundant throughout the Caspian and Black Sea basins, are among the oldest lineages still alive today, predating dinosaurs and outlasting ice ages. Slow-growing and long-lived, they can take over a decade to mature, which has made them especially vulnerable to human pressures. Decades of overfishing, poaching, habitat loss, and industrial pollution in the Caspian Sea have driven wild populations to the brink of extinction; today, virtually all Osetra caviar comes from aquaculture.
At Marshallberg Farm, Russian sturgeon are raised in a fully closed-loop, recirculating aquaculture system (RAS) that safeguards the species’ future while producing caviar of extraordinary quality. Every fish is nurtured from hatch to harvest under pristine, meticulously filtered water conditions, free from antibiotics, hormones, or chemical preservatives. Fed a premium diet formulated specifically for Acipenser gueldenstaedtii, these sturgeon develop the firm texture and nutty, buttery flavor that define true Osetra caviar. Beyond luxury, each harvest represents a conservation victory—a sustainable alternative that relieves pressure on one of the planet’s most endangered animal families. Majestic, resilient, and deeply symbolic, the Russian sturgeon embodies the possibility of restoration through responsible aquaculture.
