Taxon Name: Sinanodonta woodiana (Lea, 1834)
Synonym(s):

• Anodonta woodiana
Regional Assessments:

Common Name(s):

Chinese Pond Mussel
Taxonomic Notes:
Anodonta japonica (Von Martens 1874) is part of this species complex, however, there is no available
information for this synonym. Anodonta lauta and A. calipygos were treated as separate species by
Kondo (2008). A large number (103 at present) of synonyms of this species have been described (see
MUSSELp; Graf and Cummings 2011).
Assessment Information
Red List Category & Criteria:
Least Concern ver 3.1
Year Published:
2011
Date Assessed:
July 22, 2011
Justification:
The species has been assessed as Least Concern. This species has a widespread and stable native
distribution. It is a habitat generalist and successful in introduced areas, expanding its range throughout
the northern hemisphere.
Geographic Range
Range Description:
The species is native to temperate and tropical eastern Asia, primarily the Amur and Yangtze basins
(Soroka 2005, Kraszewski and Zdanowski 2007), and has also been very widely introduced within Asia,
Europe and the Americas. Its native range is uncertain, but ranges from Indochina and China, north to
Korea, Japan, Primorye and the Amur Basin in eastern Russia (Graf 2007). The species native range in
Indochina is unclear; it appears to be native to Viet Nam (from ‘Cochin’ as the synonym Anodonta
jourdyi Morelet, 1886) and perhaps Cambodia, but Brandt (1974) considers the species to have been

introduced to Thailand, Malaysia, Singapore, and other countries in southeast Asia.
It is one of the only members of Unionidae that has been introduced around the world (K. Cummings
pers. comm. 2011). It was first introduced to Europe in 1963 along with introduced carp, and is currently
found in at least fifteen European countries including Romania, Czech Republic, Belgium, Hungary,
France, Slovakia, Austria, Poland, Ukraine, Italy, Germany, Serbia, Bulgaria, Moldova, Spain and Sweden
as well as in some Indonesian islands (exact location unclear), Dominican Republic, USA (New Jersey),
and Costa Rica (Paunovic et al. 2006, Bogan et al. 2011, K. Cummings pers. comm. 2011).

Population
There is no population information available for this species.
Current Population Trend: Unknown
Habitat and Ecology (see Appendix for additional information)
This species is a habitat generalist found in heavily modified and artificial habitats and is tolerant to high
siltation rates (Paunovic et al. 2006). In the Czech Republic it is found in ponds, oxbow lakes and canals
(Beran 2008). It prefers substrates of silt and clay, turbid conditions with relatively high water
temperatures (30-33° C ) and is found in either standing or slow-flowing water (Soroka 2005, Zettler and
Jueg 2006).
Systems: Freshwater
Threats (see Appendix for additional information)
It is unknown whether this species is impacted by any major threats. However, it should be noted that
this is an invasive species in Europe, the Caribbean, Indonesia and elsewhere. This species is likely to be
undergoing localized declines due to urbanization, habitat degradation and alterations to the
hydrological regime.
Conservation Actions
There are no conservation measures in place or needed for this species. Research into the threats
affecting this species within its native range, as well as its population size and trends, should be carried
out, as localized threats may be affecting this species.
