The SiberianSturgeonis killed for its eggs and its meat, which is why it has been the objective of exhaustive fi shing all over the world. The main producer of Siberian sturgeon caviar is France, while the largest meat producers are Russia and China.
Since the 1940s, this species has attracted considerable attention because of its plasticity; in the 1950s, tests were carried out to introduce the species into various open stretches of water (Baltic Sea) or closed areas (lakes). The farming of this species
began in the former USSR in the 1970s.
It’s listed as an endangered species because its total population has declined between 50% and 80% during the past 60 years (three generations of sturgeon).
Overfi shing, poaching, and dam construction have caused this decline. In the wake of over-fi shing, the harvest and sale of black caviar was banned in Russia in 2007. The ban on sturgeon fi shing in the Caspian Sea has led to the development of aquaculture as an economically viable means of commercial caviar production.
The Siberian sturgeon is a large fi sh found in rivers and lakes throughout the Siberian region of Russia.
The Siberian sturgeon is a benthic species. Benthic species live at the bottom of a body of water.
Siberian sturgeon usually weigh about 65 kg, with considerable variability between and within river basins. The maximum recorded weight was 210 kg. Eggs are harvested either by repeated abdominal massaging at two-hourly intervals or (better still) by carrying out a small laparotomy.
Harvests vary from between 8% to 14% of the female live weight.
