(Huso huso)



The beluga is a very large fish reaching an average length of 5 m for a mass of 1000 kg that could live up to 150 years (confirmed age,118 years ).The largest ratio generally accepted is a female caught in 1827 in the Volga estuary of 7.2 m and weighing 1,571 kg Several other reports speak of older sturgeons exceeding 5 m in length.These large sizes make the beluga the largest freshwater fish in the world,and a rival for the moon fish,among all living bony fishes.Beluga also rivals the great white shark,the Greenland shark and tiger shark for the title of largest predatory fish.The beluga is much larger than theMekong giant catfish or pirarucu.Nevertheless,some scientists believe that the giant Mekong catfish is the largest true freshwater fish,because of the sturgeon's ability to live in seawater and spend much of its life in the water.brackish
