A beluga or European sturgeon (Huso huso) captured in 1922 in the Volga Estuary. The population of the Beluga Sturgeon has decreased by as much s 90% over the last 60 years. A large sturgeon, it reaches a length of 8 metres (26.2 feet) and a weight of 3.2 tonnes (3.5 short tons), but its flesh and caviar are less valuable than those of smaller species. Beluga sturgeon, the largest available sturgeon species, can reportedly reach up to 10 meters and 4,500 pounds in size, though around 5 to 7 meters and 2,500 pounds seems to be more normal. Caviar is the table name for fish eggs, and beluga sturgeon produce millions of eggs. Again depending on various factors, belugas can grow about a meter every 2-10 years.

The beluga or European sturgeon (Huso huso) is a large predator which feeds mostly on fish, also rarely consuming waterfowl and seal pups.

The Beluga Sturgeon is the largest freshwater fish in the world.

Sturgeon date back to the Triassic period, nearly 250 million years ago and are widely considered living fossils due to the slow path of evolution they have endured over millennia. The beluga, or hausen (Huso huso), inhabits the Caspian and Black seas and the Sea of Azov. The size of some historic wild Beluga sturgeon has classified them in some realms as the largest freshwater fish, having reached weights over 3000 pounds. The largest reported beluga sturgeon was 7.2 meters long and 3,463 pounds. The size of some historic wild Beluga sturgeon has classified them in some realms as the largest freshwater fish, having reached weights over 3000 pounds. The eggs of a female Beluga Sturgeon (also known as roe or caviar) sells for an average of $7,000 per kilogram It is not a record-breaker, but probably at 7 meters (23 feet), one of the largest European sturgeons ever caught. The beluga sturgeon is, unfortunately, cursed with producing some of the most desirable caviar in the world.
