Poaching and trafficking are major threats to the survival of four sturgeon species in one of their last strongholds—the lower Danube River in southeastern Europe. According to a recent report by the World-Wide Fund for Nature (WWF), these illegal activities are severely impacting the already endangered fish species.
Key Findings
- Illegal Activities Reported: The WWF report documented 395 cases of illegal sturgeon fishing and trade between 2016 and 2023 across Bulgaria, Romania, and Ukraine, affecting 1,031 sturgeon individuals. This figure represents only a fraction of the total illegal activities, as many cases remain undetected.
- Geographic Distribution:
- Bulgaria: 144 cases
- Romania: 157 cases
- Ukraine: 94 cases
- Fishing Methods: In Bulgaria and Romania, illegal fishing primarily involves traditional unbaited hook lines known as karmaci, despite their ban. Authorities in Bulgaria alone seized 988 karmaci, totaling approximately 37 kilometers.
- Impact on Sturgeon Species:
- Romania: 610 sturgeons affected
- Ukraine: 418 sturgeons affected
- Bulgaria: 3 sturgeons affected
Sturgeon Species at Risk
- Historical Decline: Of the six sturgeon species formerly native to the Danube River, two—European sturgeon (Acipenser sturio) and ship sturgeon (A. nudiventris)—are now considered locally extinct.
- Current Threat Status:
- Stellate sturgeon (A. stellatus), Russian sturgeon (A. gueldenstaedtii), and Beluga sturgeon (Huso huso) are Critically Endangered.
- Sterlet (A. ruthenus) was recently upgraded to Endangered status as of 2022.
- Species Affected by Poaching:
- Sterlet: Most frequently reported, with 78 cases in 2018.
- Stellate sturgeon: Reported in 76 cases over the last four years.
- Russian sturgeon: Reported in 39 cases.
- Beluga sturgeon: Reported in 32 cases.
- Unspecified species: Mentioned in 37 cases.
Hotspots for Trafficking
- Primary Locations:
- Vratsa, Bulgaria
- Tulcea, Romania
- Odesa, Ukraine
Conservation Recommendations
The WWF report emphasizes the need for better enforcement and comprehensive data collection across the region to understand and combat sturgeon trafficking more effectively. The Lower Danube Basin is identified as a critical area for conservation efforts to protect the remaining sturgeon populations.
