Sterlet: A. ruthenus
As one of the smallest representatives of sturgeon, the sterlet is also interesting for medium-sized ponds. The sturgeon, which used to be native here, is brownish in colour with many small bone plates and white fin seams. It quickly becomes sexually mature and is often used as a parent for hybrids. As the only sturgeon species it is viable with albinism and is then a special attraction as a snow-white sturgeon in the pond.
