Dabry's sturgeon (Acipenser dabryanus), also known as the Yangtze sturgeon, Changjiang sturgeon and river sturgeon, is a species of fish in the sturgeon family, Acipenseridae. [5] It is endemic to China and today restricted to the Yangtze River basin, [ 1 ] but was also recorded from the Yellow River basin in the past.
The Yangtze flows through a wide array of ecosystems and is habitat to several endemic and threatened species, including the Chinese alligator, the narrow-ridged finless porpoise, and also was the home of the now extinct Yangtze river dolphin (or baiji) and Chinese paddlefish, as well as the Yangtze sturgeon, which is extinct in the wild.

Conservation efforts at the grass roots level are also instrumental in helping to preserve sturgeon populations, such as Sturgeon For Tomorrow [62] which was founded in 1977, consists of volunteers and a sturgeon guarding program to monitor known spawning sites. The organization has grown exponentially over the years and has become "the largest ...
The goal is to restore a wild, self-sustaining lake sturgeon population in the urban river that runs up the northeast side of the metro area. Its primary partners are Riveredge, the Wisconsin ...
The Yangtze River Plain stretches 1,000 km from the Three Gorges to the sea. The terrain is mostly flat or low alluvial hills, with numerous shallow lakes. Large lakes include Poyang Lake, the largest freshwater lake in China, and Dongting Lake which was formerly the largest but has seen significant conversion to farmland over the years.
A 2019 paper including scientists from the Yangtze River Fisheries Research Institute found the species to be extinct. [4] It was unanimously agreed to be extinct by the Species Survival Commission Sturgeon Specialist Group of the IUCN on 15 September 2019, [5] with its conservation status being formally updated by the IUCN Red List in July ...
