Ecology Sinanodonta woodiana, the Chinese pond mussel, is a species of East Asian freshwater unionid bivalve mollusk primarily known from the Amur River, in the Russian Far East, and China's Yangtze River. The Chinese pond mussel can grow to 30 cm and attain an age of 12–14 years, and they can reproduce by the end of their first year, while only 3–4 cm in size.US Fish and Wildlife Service, 2015. "Chinese Pond Mussel (Sinanodonta woodiana) Ecological Risk Screening Summary"

This large, freshwater bivalve is a habitat generalist, with a high silt tolerance. It is established worldwide; like all unionid mussels, it has an obligatory parasitic stage (glochidium), in which the larva must encyst on a host fish to complete its development. Host species include invasive, non-native and native fishes.Douda, K., Vrtílek, M., Slavík, O., & Reichard, M. (2012). The role of host specificity in explaining the invasion success of the freshwater mussel Anodonta woodiana in Europe. Biological Invasions 14:127–137.. The presence of S. woodiana can seriously affect local unionid populations.

S. woodiana'''s great success is attributed to the importation and commercialisation of Asian carp, its native Asian host, which is now found worldwide, as well. S. woodiana was introduced in Tuscany both inadvertently and intentionally, for artificial/imitation pearl production. The species is also sold in some garden centers as biofiltration for outdoor ponds and water features.
