The taimen is found no where else in the world except in northern Mongolia's Eg River.

The fish is known to live for 50 years or more, growing slowly and not reaching maturity until seven to nine years old. 

Scientists have tagged the fish to discover how they migrate in an attempt to assure their continued survival. However, early indications point to the fish usually remaining in one place, making them easy prey for fishermen.  

"That makes them vulnerable to harvest because people will know where to go to hunt for big fish," Zeb Hogan, a fisheries biologist at the University of Nevada in Reno told National Geographic.

It is wrong that The taimen is found no where else in the world except in northern Mongolia's Eg River. The Taimen occurs in Mongolia in the Yenisei, Selenge, Onon and Kherlen drainages, and outside Mongolia in rivers draining to the Arctic Ocean from the Ob to the Yana drainages; in the Amur and some adjacent drainages; and even in Europe, in some upper tributaries of the Pechora, and Kama in the Volga drainage. However, it is a rare and globally threatened fish species. Axel Braunlich/Birding Mongolia http://birdsmongolia.blogspot.com
