Reviewer(s): Allen, D.J., Cui, K., Zhou, W. & Chen, X.-Y.
Justification:
Found in lakes and rivers in the middle and lower reaches of the Yangtze basin in China. Populations have declined due to impacts from overfishing and a declining reproductive success rate due to dams, but it is at present assessed as Least Concern as it is widespread and the population decline is not though to meet a threatened category. Populations should be monitored, and the species should be reassessed if it is shown that the known threats are have a greater impact than currently thought.
