The Kaluga (Huso dauricus) is a large predatory sturgeon found in the Amur River basin. Also known as the river beluga, they are claimed to be the largest freshwater fish in the world, with a maximum size of at least 1,000 kg (2,205 lb) and 5.6 m (18.6 ft). Like the slightly larger Beluga, it spends part of its life in saltwater. The Kaluga is one of the biggest of the sturgeon family.
Kaluga caviar comes from the Kaluga "River Beluga" sturgeon.
