Abstract: Aquaculture escapes include several pathways. Direct escapes provide us a “natural” experimental experiment for fish invasion ecology. Indirect escapes are released by local people. An additional escape of agriculture is from the abandonment of ornamental fishery. Taking alien sturgeon escape in Qingjiang River basin in 2016 as an example, we discussed the potential impacts of these escapes on alien species invasion in the Yangtze River, including their hybridization and competition with native species Acipenser sinensis (a protected species at national level), and spread of disease. We conclude that public education on the ecological impacts of indirect releases of aquaculture species needs to be strategically emphasized in the region. Meanwhile, sound monitoring programs and controlled releases are also needed to reduce their impacts. This review also pointed out the directions of monitoring and tracking direction after aquaculture escapes and the prospects of the future development direction of impact assessments of aquaculture escapes on the alien species invasion in the Yangtze River.
