<em>Macrobrachium nipponense</em> is a major farmed species of freshwater shrimp in China and its genetic diversity is of high value in aquaculture. The construction of the Three Gorges Project has slowed down the flow velocity of water in the Three Gorges Reservoir (TGR) and made the water more clear, which is more favourable for the survival and reproduction of <em>M. nipponense</em>. However, there is a lack of studies on the genetic diversity of <em>M. nipponense</em> populations in the TGR. In this study, mitochondrial COI gene sequences were used as molecular marker to analyze the genetic diversity, genetic differentiation and historical demography of eight populations of <em>M. nipponense</em> in TGR.
