Three Gorges Dam: the changing trend of snail density in the Yangtze River basin between 1990 and 2019

ConclusionsSnail density exhibited a fluctuating downward trend in the Yangtze River basin. In the downstream area, the operation of TGD accelerated the decline of snail density during the first decade period, then snail density fluctuated at a relatively low level. There still exists local areas with a high snail density. Long-term control and monitoring of snails need to be insisted on and strengthened.Graphical Abstract
