Condition for keeping sturgeons in the aquarium

Due to the stature and the beauty of sturgeons, tendency to keep them in the aquarium has increased. There are 27 species of sturgeon in the world that have inhabited the lakes and rivers of the northern hemisphere. There are 6 sturgeon species in the Caspian Sea. Amongest the sturgeons of the Caspian Sea and its catchment area, Sterlet (Acipenser ruthenus) and Stellate sturgeon (Acipenser stellatus) are more suitable for keeping in the aquarium than other species of sturgeon. But Sterlet is more important for keeping in the aquarium. Ofcource, it is possible to keep other sturgeon species in the aquarium. However, due to their higher growth rate, they were more difficult to maintain in the long time and needed aquariums with more water volume and dimensions. To maintain sturgeon in an aquarium, the length and width of the aquarium should be large enough so that the fish can swim freely and swing easily. This means that, the length of the aquarium should be, at least 6 times the length of the fish and its width at least 2 times the length of the fish. Water depths are less important, but more water volume, provide more sustainable encvironmental condition. Sturgeons feeds throughout the year, but the amount of food consumed is lower in the winter. Their food is comparable to other carnivorous fish. In general, from the aspect of existence specific, sturgeon fish are intermediate salmonids and cyprinids.
