Mandarin fish, Siniperca chuatsi (Basilewsky), is a famous freshwater fish in China and has a relatively high market value. The fish have been stocked in lakes since the 1990s to increase populations, to pursue commercial returns and to ease conflicts between fishery development and water quality conservation. In this paper, we briefly review the status of stock enhancement of mandarin fish in China. The parameters of stock enhancement techniques including stocking size, stocking habitat, and stocking number are determined by a series of comparative experiments. Stocked mandarin fish showed good survival and growth performance, and consequently obtain better economic benefits compared with traditional fisheries of stocking. Impacts of stocked mandarin fish on wild mandarin fish populations and small-sized fish community are also dealt with. Stocking mandarin fish in lakes may have a positive role for improving water quality, suggesting that mandarin fish stocking could be a feasible bio-manipulation measure to alleviate eutrophication in Yangtze lakes.
