This sturgeon has been known to reach 2.5 m in length, but it is usually much smaller. Its body is blue-gray above and yellowish white on the belly, with five rows of scutes . The head is triangular and the snout is long with the mouth located on the underside. There are two pairs of barbels .
The fish lives in slow-moving river waters over substrates of sand and mud. It feeds on aquatic plants , invertebrates, and small fish. This species is potamodromous, taking part in a migration , but never leaving fresh water. It spawns in the upper Yangtze, mainly during March and April, and sometimes around November and December. Males spawn each year, but most females do not. The female produces 57,000 to 102,000 eggs.
This was once a common fish in the Yangtze system. It was known from
the main river and some of its larger tributaries , as well as some
lakes attached to the system. By the late 20th century, it was
extirpated from the lower river and limited to the upper reaches in
The fish has been bred in captivity since the 1970s. Thousands of individuals have been released into the river, but are apparently not breeding. Nevertheless, this restocking may be the only effort preventing the extinction of the species.
