The illegal trade of caviar from Europe poses a significant threat to the survival of wild sturgeon populations, according to a study conducted by a team of sturgeon experts. The research, published in the journal Current Biology, reveals that half of the tested caviar products from Bulgaria, Romania, Serbia, and Ukraine are illegal, with some not even containing any trace of sturgeon.
Sturgeon, known for their prized eggs, produce caviar, which has been illegal for several decades due to overfishing and poaching, leading to the decline of sturgeon populations. The only legal caviar comes from farmed sturgeons, and regulations are in place to protect these vulnerable species. However, the study’s findings indicate that these regulations are being actively violated.
The researchers conducted genetic and isotope analyses on caviar samples obtained from the above-mentioned countries, which border the remaining wild sturgeon populations. The results highlight that 21% of the tested samples were derived from wild-caught sturgeons, and 29% violated international trade regulations. Furthermore, 32% of samples were found to be misleading to customers, falsely claiming to be wild products when they originated from aquaculture.
The four sturgeon species found in Europe—Beluga, Russian, stellate, and sterlet—are protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) since 1998. In 2000, a strict labeling system was introduced for all caviar products to combat illegal trade. Despite these protective measures, the study reveals that illegal poaching continues to persist, endangering the already fragile sturgeon populations.
The researchers also discovered that three caviar samples served in Romania as “sturgeon soup” were not sturgeon at all. Instead, the fish identified in these samples were European catfish and Nile perch, further exemplifying the misrepresentation of caviar products.
The study suggests that the high volume of illegal poaching could be due to a lack of alternative income opportunities for local seafood vendors. It also indicates a possible lack of effective law enforcement in these regions, as authorities may not prioritize halting illegal poaching or may lack the necessary resources to prove the illegal origin of fish.
The researchers emphasize the urgency of taking action to address the illegal caviar trade. They stress the need to improve the control and regulation of caviar and sturgeon trade in the European Union (EU) and candidate member states to ensure the future survival of Danube sturgeon populations.
Additionally, the study reveals that there is still significant consumer demand for wild sturgeon products, despite the availability of aquaculture alternatives. This persistent demand fuels poaching and raises concerns about the effectiveness of the current labeling system and controls in place.
The findings of the study highlight the need for stronger enforcement measures and international cooperation to combat the illegal caviar trade and protect wild sturgeon populations. The authors urge swift action to address this issue and prevent further harm to these vulnerable species.
