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.

The Kaluga Sturgeon is listed as 'Endangered' on the IUCN Red List of Threatened Species. The decline is mainly due to severe over fishing since the 19th century. Mature fish now account for only 2-3% of the population and, due to the low reproductive rate and late maturation, the decline is expected to continue.
