Vietnamese and South Korean Caviar

In 1996, South Korea’s Somijn River Cultured Fish Farm imported sturgeon fingerlings from Japan. FAO also records its development of caviar production. Vietnam’s documented experimental rearing history reaches back to 2005, with imported eggs. These are caviar industries built through hatcheries, specialist farms and, in Vietnam, cool highland waters and reservoirs. A country name identifies none of the essentials on its own: which sturgeon supplied the roe, which farm raised it or whether it qualifies for export.

Vietnam: country facts

• Species documented: Siberian sturgeon (Acipenser baerii) and Russian sturgeon (Acipenser gueldenstaedtii) in research ^1,2; Vietnam Sturgeon Group also reports sterlet and beluga ³.
• Farming regions: Lâm Đồng and the northern highlands, including Sa Pa and Văn Chấn; Sơn La reservoir farming is also documented.
• CITES operations: CITES requires registration of processing and repackaging plants involved in caviar exports.
• Trade regime: Vietnamese CITES permits plus destination food-import rules, including EU Regulation 2021/405, GB approval requirements and US Seafood HACCP.
• PGI or PDO: No caviar designation reliably established.
• Wild stocks: The documented Siberian and Russian farm stocks are introduced ^1,2.
• Role: Origin of farmed fish and roe, with a domestic market and reported export activity.

South Korea: country facts

• Species documented: Siberian sturgeon (Acipenser baerii) and Russian sturgeon (Acipenser gueldenstaedtii), with other species and hybrids discussed in Korean research.
• Farming regions: Historical production reporting documents the Namhan River area ¹⁰. A 2018 thesis documents farming in Hamyang.
• CITES operations: CITES lists four Korean businesses as exporters, combining processing and repackaging in one activity column.
• Trade regime: Korean CITES permits plus destination food-import rules, including EU Regulation 2021/405, GB approval requirements and US Seafood HACCP.
• PGI or PDO: No caviar designation reliably established.
• Wild stocks: Chinese sturgeon (Acipenser sinensis) historically occurred off southwest Korea ¹². NOAA gives its present range as the lower Yangtze and Yellow and East China Seas, separate from introduced farm stocks.
• Role: Domestic caviar producer and market, with registered exporters; shipment volumes are not established by registration.

Vietnamese caviar: highland beginnings

Imported eggs laid the groundwork for Vietnam’s experimental sturgeon rearing. A Vietnamese study of Siberian sturgeon reproduction, published in 2016, traces that early work and describes the broodstock research that followed at Văn Chấn in Yên Bái and Sa Pa in Lào Cai between January 2012 and May 2015.

Commercial development took root in the Central Highlands. Vietnam Sturgeon Group dates its Lâm Đồng activity to 2007 and the addition of Russian sturgeon and beluga to 2008. Those dates describe the producer’s own history rather than an independently established chronology for the whole country.

The research gives the fish their precise identities. Vietnamese studies document Siberian and Russian sturgeon, including experiments rearing Russian sturgeon fry at different stocking densities. That is evidence of the species being studied and raised; commercial roe harvesting is a separate stage to establish.

Where Vietnam’s farms operate

Vietnam’s caviar landscape is one of highlands and reservoirs, a more revealing picture than “tropical caviar”. Vietnam Agriculture and Nature reported farms around Đà Lạt, Lạc Dương, Đam Rông and Di Linh in Lâm Đồng in March 2022. Northern research and production records identify Sa Pa, Văn Chấn and Sơn La’s hydropower reservoir.

Lâm Đồng’s reported average temperature of 18 to 24°C describes the region, not measured annual farm water temperatures. Vietnam Sturgeon Group describes adapting its farming to reservoirs.

Fish and roe both matter here. The March 2022 Lâm Đồng reporting covers commercial sturgeon, fingerlings and caviar; Sơn La reporting from April 2025 discusses meat and roe. These describe a mixed industry without establishing a national percentage split. Fish tonnage must remain distinct from caviar tonnage.

Vietnam’s caviar landscape is one of highlands and reservoirs, a more revealing picture than “tropical caviar”.

For the biology behind these locations, see water temperature, light and maturation. The conditions where a fish actually lives matter more than the country’s latitude.

South Korean caviar: research and specialist farms

South Korea’s industry includes research hatcheries and specialist farms. Alongside the commercial development recorded by FAO, the National Institute of Fisheries Science describes a separate sturgeon research programme beginning in 1997.

In the institute’s account, Siberian sturgeon is the most widely farmed sturgeon; Russian sturgeon also features. A Korean university thesis directly examines artificial propagation and caviar production in both. These scientific names offer a clearer guide to species than a trade description such as “Osetra”.

The industry raises fish for the table as well as for roe. Korean fisheries guidance describes males being used for food, while females need longer rearing before producing caviar. That distinction helps explain why accounts of sturgeon farming are not automatically accounts of caviar output.

Korea also has a native sturgeon history. NOAA records Chinese sturgeon historically in southwest Korean waters. That historical distribution does not connect today’s imported Siberian or Russian farming stocks to a local wild fishery.

What each country is known for

Vietnam’s distinctive combination is highland farming and reservoir culture. Vietnam Sturgeon Group describes adapting husbandry to local conditions, while provincial reporting records a substantial fish-rearing and hatchery sector. The geography is central to understanding how the industry developed.

South Korea’s record combines research into artificial propagation and caviar production with specialist farms. According to Almas Caviar, its caviar production began in 2008 following research started in 1997.

Authorities and international market access

In Vietnam, fisheries fall under the Ministry of Agriculture and Environment, through the Department of Fisheries and Fisheries Surveillance. The ministry’s quality, processing and market-development department has food-safety responsibilities. The CITES country profile places the national CITES Management Authority within the same ministry. Documents naming the Ministry of Agriculture and Rural Development belong to the structure before the 2025 restructuring.

South Korea divides these responsibilities between several bodies. The Ministry of Oceans and Fisheries and its fisheries agencies cover the fisheries sector; the Ministry of Food and Drug Safety handles food regulation. The current CITES profile names the Ministry of Climate, Energy and Environment as the principal wildlife management authority, with regional environmental offices handling permits.

Switzerland, UAE, China, Japan, Russia and Australia apply national rules. For personal travel, CITES says labelled caviar may qualify for a 125 g exemption, subject to national rules.

For commercial imports, find the destination below, read its requirements, then consult the legal framework in the final column. CITES registration and food-import permission need separate checks.

Checking the producer and the origin

Start with the named business. The CITES register lists FCR & D Korea, Dura Fishery Union Cooperation, Hamyang Sturgeon Aquafarm and HULICS F&C. CITES says this register covers caviar processing and repackaging plants involved in exports. Its combined processing/repackaging field cannot supply separate national counts for those activities; a registered office address is also distinct from a verified farm location.

Next, check the origin code. Caviar originating in Vietnam carries VN; caviar originating in South Korea carries KR. Repacking elsewhere does not change the roe’s origin. US rules for international caviar trade likewise distinguish origin from repacking information. A label supports traceability, although it cannot independently verify what is inside the tin.

For the wider regional picture, start with Asia, then compare the evidence across caviar producing countries. Japanese caviar offers a neighbouring case, while Chinese production has its own history of farming development and scale.

Match the legal producer or processor, species and origin to the supporting documents before accepting a country-of-origin claim. Use the CITES producer-register check for registration, then check food-import permission separately.
