Marshallberg Farm

Marshallberg Farm is a North Carolina producer of Osetra caviar from Russian sturgeon, Acipenser gueldenstaedtii, raised in indoor recirculating systems at Smyrna and near Lenoir. The business brings fish farming and caviar processing together, with a family-run identity centred on founder I.J. Won.

What Marshallberg Farm is known for

Marshallberg’s distinction is the combination of a familiar caviar species with an American farming origin. Russian sturgeon is the species; Osetra is the trade name the farm uses for its salted roe, not a statement that the fish were raised in Russia. North Carolina State Extension independently describes sturgeon farming in the state as RAS production at two locations.

For a connoisseur, that is a provenance distinction rather than a promise about every tin’s flavour. The relevant comparison is between farming and processing arrangements, not simply between national brand identities. The broader regional context is covered in American caviar in the eastern states.

Ownership and the two farm sites

The company’s privacy notice identifies the operator as Marshallberg Farm LLC, doing business as Marshallberg Farm, at the Smyrna address. Its ownership page names I.J. Won, a former North Carolina State University geophysics professor, as owner, and describes management involving his daughter Lianne and her husband Brian.

The farm dates its start to 2010, while Won’s account describes preparatory RAS construction beginning in 2008. The company gives 2010 as its start date and separately describes construction beginning in 2008. A 2013 submission to the US Fish and Wildlife Service already describes Marshallberg as a family-operated business raising Russian sturgeon.

The second site is not merely a distributor’s address. Won’s account records the acquisition of the Lenoir farm in 2017, now called Marshallberg Farm West. NC State’s annual report for 2016 to 2017 separately records the university’s divestment of its interest in the LaPaz caviar farm; reporting in 2018 places Marshallberg’s acquisition in June 2017.

How the sturgeon are farmed

RAS means recirculating aquaculture system: water is treated and returned to the fish tanks rather than used only once. Marshallberg describes indoor production independent of a lake, river or pond, with more than 95% water recycling.

The farm’s published production account describes hatching eggs, growing juveniles in nursery tanks, then moving them into larger production tanks. Staff separate males and females as the fish grow, and assess females with ultrasound and biopsy before selecting fish for harvest. Selected fish are then moved into separate clean-water tanks before processing.

A North Carolina agriculture department interview in 2021 provides a useful corrective to the idea that fish farming is mainly feeding fish. Farm manager Brian Reburn described maintenance, cleaning and tank data recording as central daily work. For the engineering behind those tasks, see recirculating aquaculture systems rather than treating RAS as a quality grade.

Species, stock origin and product names

The documented caviar species is Russian sturgeon, Acipenser gueldenstaedtii. Marshallberg’s website specifically presents its fish as pure Russian sturgeon, not hybrids. Its Osetra name therefore maps to that species in this producer’s range; it should not be used to infer the species behind another house’s similarly named caviar.

The non-native fish arrived through aquaculture, not through capture in North Carolina waters. A Carolina Shore interview reproduced by the farm describes fertilised Russian sturgeon eggs arriving from Germany and refers to a Fish and Wildlife import licence.

This distinction matters when reading origin claims: imported fertilised eggs are starting stock, not imported finished caviar. Marshallberg presents its caviar as roe produced from fish raised in the United States. For biological detail, use the separate guide to Russian sturgeon and Ossetra, rather than interpreting a trade name as a geographical certificate.

Names displayed within its range include Classic, Traditional, Royal and Gold Reserve Osetra. They are the company’s product distinctions, not additional sturgeon species or government quality grades. These names distinguish products within Marshallberg’s range; they do not establish different geographical origins.

Roe sourcing and routes to market

Marshallberg markets caviar as its own farm production and describes the ingredients as roe and salt. Its website also says that higher grades are packed into their final tins on harvest day.

The documented channels are direct retail and wholesale supply. The farm maintains a wholesale programme for established businesses, while a 2018 report recorded distribution through smaller businesses and a New York distributor. Those routes show that a farm’s caviar can reach diners through intermediaries, without establishing that any particular outside brand currently contains Marshallberg roe.

The public CITES register marks Marshallberg’s exporter status as No.

Registration, permits and reading the label

The public CITES register lists Marshallberg Farm, LLC at Smyrna with codes M001 and L001. Its exporter field says No, while its combined processing/repackaging field says Yes. The entry does not separate those two activities, and the two codes should not be assigned to individual farm buildings without further documentation.

Label and batch records provide information about origin and processing, and consult the CITES operation register. A CITES label supports traceability; it does not independently prove a tin’s contents.

State aquaculture licensing is a separate matter. North Carolina’s agriculture department issues aquaculture licences and explains that species outside its approved list require written permission from the Wildlife Resources Commission. According to North Carolina’s agriculture department, aquaculture licensing and permission to culture species outside the approved list are separate requirements.

For US food naming, FDA’s nonbinding CPG 540.150 says unqualified caviar should mean salted sturgeon roe. Product names require matching type prominence; ingredients follow descending predominance, and artificial colour requires prominent declaration. This naming guidance is distinct from wildlife-trade registration; the wider legal explanation is in US caviar rules.

Sustainability and scale claims

Marshallberg calls its production sustainable and describes the two farms as the largest RAS sturgeon operation in North America. In January 2021, North Carolina’s agriculture department described Marshallberg as North America’s largest producer of Russian sturgeon and Osetra caviar.

Its more concrete environmental account concerns water reuse and contained waste. These describe aspects of the production system, not a complete assessment of energy, feed, welfare or lifecycle impacts. They are more informative when kept separate from the broader assertion that farmed supply counters poaching, which expresses the company’s conservation rationale rather than a measured reduction in illegal catches.

What to request from the producer

Professional comparisons can consider dated specifications covering species, farming site, processing site, ingredients and batch traceability. Keep the producer’s declarations alongside the registration record, rather than merging them into one assurance. The parent guide to caviar houses and producers explains the different roles a business can occupy, from fish farmer through processor to repacker and distributor.
