Fuxian carp is concentrated in the middle and lower layers of the shallow waters along the coast, and a few individuals are also found in the middle and lower layers of the wading area, with a living depth of about 20-30m. It mainly feeds on mollusks, and also feeds on chironomid larvae, zooplankton and filamentous algae. It is an omnivorous fish that mainly feeds on mollusks. The spawning time is from April to May, and the spawning grounds are concentrated in the still water of the lake bay with rich aquatic plants. The eggs are sticky, and the fertilized eggs stick to the aquatic plants to hatch.

Yunnan is the center of differentiation of carp fish in my country. Fuxian carp is a unique fish in Fuxian Lake and Xingyun Lake in Yunnan. It is an important group in systematic taxonomy research and a precious germplasm resource in fisheries.

Fuxian carp is very rare. The population distributed in Xingyun Lake has not been seen for many years. In 2002, one tail was collected in Fuxian Lake, indicating that it is endangered but not extinct.
Overfishing by net boats is the main reason for the depletion of Fuxian carp resources. In addition, since the introduction of species in these lakes in the 1960s, a large number of wheatear fish, yellow croaker and forged tiger fish have been introduced. These small fish breed in groups, live on the lakeshore, and swallow the fertilized eggs of these economic fish in large quantities, seriously reducing the replenishment of the population and eventually leading to the depletion of resources. There is no record of breeding. Conventional fishery management is implemented, including regulations on fishing bans, but overfishing has been repeatedly banned.
