- Stellate Sturgeons stop eating once they start their migration. After spawning, they return to the sea quickly where they begin feeding again.
- 87% decline in global commercial catch reflects the decline in species population.
- 55,000 sturgeons found dead in the Sea of Azov in 1990 as the result of pollution.
- 72.5% is the decline of Stellate Sturgeon catch over a 4-year period according to data from Romania.
