The catches were dominated by juveniles varying from 35 to 45 mm standard length in August 2015 . This species was not observed in Nansi Lake in our previous surveys and was not reported by fishermen before. We then specifically surveyed the other lakes along the ESNT for this species and found that it was distributed throughout Luoma Lake in July 2015 . We also first observed this fish in Dongping Lake in November 2016 . However , it has not yet been observed in Hongze and Gaoyou lakes. We observed adults with well-developed gonads and new recruitment of young-of-the-year juveniles of this species in Nansi Lake since 2016, suggesting successful establishment of the population . The ESNT operated from April 21 to July 1, 2015 , transferring water up to Dongping Lake. Dispersal of drifting larvae has been reported as the primary way that this species expands its distribution ( Matern and Fleming 1995 ). Water transfer events in 2015 covered the spawning season of this species ( Matern 1999 ). The dispersal of drifting larvae, probably from the Yangtze Estuary, through water flow by the water transfer events, may explain occurrence of this fish in the lakes.
