About Sturgeon:

It is among the most endangered fish species globally.
These species have been around since the age of the dinosaurs.
Distribution: These northern hemisphere fishes can be found in large river systems, lakes, coastal waters and inner seas throughout Azerbaijan, Bulgaria,other European countries and North America.
Since 1998, international trade in all species of sturgeons has been regulated under CITES owing to concerns over the impact of unsustainable harvesting of and illegal trade in sturgeon populations in the wild.
Threats: Sturgeons are heavily exploited globally for their roe/eggs (caviar) and meat. This has led to a steep decline in populations worldwide.
