The Chinese paddlefish was considered anadromous with upstream migration, however little is known about their migration habits and population structure. They were endemic to the Yangtze River Basin in China where they lived primarily in the broad surfaced main stem rivers and shoal zones along the East China Sea .
The American paddlefish (Polyodon spathula), also known as a Mississippi paddlefish, spoon-billed cat, or spoonbill, is a species of ray-finned fish. It is the last living species of paddlefish (Polyodontidae).
The Chinese paddlefish (Psephurus gladius; simplified Chinese: 白鲟; traditional Chinese: 白鱘; pinyin: báixún: literal translation: "white sturgeon"), also known as the Chinese swordfish, is an extinct species of fish that was formerly native to the Yangtze and Yellow River basins in China.
The American paddlefish is one of the largest freshwater fish in North America. Closely related to the sturgeon, it is one of only two extant taxa in the paddlefish family (the other being the Chinese paddlefish). Fossil records of paddlefish date back over 300 million years, nearly 50 million years before dinosaurs appeared.

Reportedly, fisherman as recently as the 1950s have caught paddlefish measuring up to 6.7 m (22 ft) in total length, although no specimen greater than 3.1 m (10 ft) has been scientifically measured. The weight of the Chinese paddlefish is reportedly 300 to 500 kg (660 to 1,100 lb). [76] [77] Bonefish (Albuliformes)
The estimated time of the divergence between sturgeons and paddlefish varies. An estimate based on 30 protein-encoding nuclear markers suggest 204.1 million years ago, research on mitochondrial genomes suggest 155.2 million years ago, and Bayesian dating based on the combined matrix of molecular (mitogenomes) and morphological characters set ...
The American paddlefish is the only species of paddlefish living after the extinction of the Chinese paddlefish, which was estimated to be extinct by 2005, and no later than by 2010. [6] Sturgeons are considered by IUCN to be the most critically endangered group of species in the world based on over 85% of sturgeon species being at risk of ...
