There are not many freshwater fish which have a tail like this.

It reaches a maximum weight of about 15 pounds. The construction of dams for flood control and hydropower has reduced the river's natural turbity, lowered water temperatures, and restricted the natural flow of the river, thereby altering the conditions sturgeons need for successful spawning. It was also once found in the Aral Sea, but according to NASA, the Aral Sea shrunk by more than 60 percent between 1973 and 2000. Please check your entries and try again.
