> Habitat & Distribution

Bellamya chinensis populations are widely introduced throughout the United States, especially in northern latitudes, extending into Canada (Clench & Fuller 1965, Clarke 1981, Jokinen 1982).  The ANSP holds quite a few lots collected in the 1950s and 1960s from southeastern Pennsylvania.  As of 2018 we were aware of approximately 50 populations in our study area, roughly half In Atlantic drainages and half in drainages of The Ohio, generally inhabiting ponds, lakes, reservoirs, and larger rivers.

Although we are aware of several B. chinensis populations in Kentucky, we have no confirmed records south of the Mason-Dixon line.  The earliest reports of Bellamya in the American southeast were, however, records of “Viviparus” or “Cipangopaludinachinensis in Alamance and Pitt Counties, North Carolina from the 1940s (Clench & Fuller 1965), with a Wake County record added in 1977 (Cordiero, pers. comm). Directed searches conducted 2011-12 have failed to confirm Bellamya populations (of either species) at any of these sites - Alamance, Pitt or Wake.  Nor have we been able to confirm two subsequent records of B. chinensis from Virginia (Stewart & Dillon 2004), although B. japonica is not uncommon in the Old Dominion.  FWGNA incidence rank I-4.

> Ecology & Life History

We are not aware of any ecological differences between B. chinensis and the (very similar) B. japonica, which may have been introduced together, and occasionally occur in mixed populations.  See our Bellamya japonica page for more detailed discussion of the ecology, origin and spread of Bellamya in North America.

The (surprisingly sparse) life history studies of B. chinensis suggest that maturity may be reached at age one year, with iteroparous reproduction for several years thereafter (Life cycle G, Stanczykowska et al 1971, Jokinen 1982, Therriault & Kott, 2002).  Jokinen’s (1987) analysis of the distribution of B. chinensis in Connecticut and New York led her to classify it as a “C-D tramp,” potentially present in nearly every community.  Dillon’s (2000) reanalysis of these data suggested that B. chinensis populations in Connecticut seem to be Undifferentiated with respect to life history adaptation.

Bellamya
populations sometimes seem to reproduce explosively, then suffer dramatic crashes, as might be associated with semelparous reproduction (see my essay of 5Aug14 below).  The adult population of B. chinensis inhabiting a 1.46 ha New York pond increased from approximately N = 150 in the sampling season of 2010 to N = 1000 in 2012 (McCann 2014).  Chaine and colleagues (2012) estimated an adult population size of 253, 570 in a 6.47 ha Nebraska reservoir, 39% of which died the following year (Haak et al. 2013).  But it seems more likely to us that such mortalities may be better attributable to the colonization of marginal habitats as a consequence of population flushes accompanying invasion.  

Huehner and Etges (1977) reported the development of the trematode Aspidogaster conchicola - typically considered a bivalve parasite - in an Ohio population of "Viviparus malleatus." Prezant et al. (2006) reported that populations of B. chinensis in New Jersey may react to crayfish predation by producing larger numbers of offspring, smaller and more variable in size.

> Taxonomy & Systematics

See under B. japonica for notes regarding the generic taxonomy.  We suspect that most (perhaps all) of the historic records of B. chinensis from Atlantic drainages south of the Maxon-Dixon line may be traceable to confusion with B. japonica.  Both of the records of B. chinensis in the Virginia Museum of Natural History relayed by Stewart & Dillon (2004) proved to be based on B. japonica upon examination of the museum lots.

Reeve (1863) described Paludina malleatus without distinguishing it from J. E. Gray’s (1834) P. chinensis, or indeed from any other oriental viviparid.  Clench & Fuller (1965) considered malleata (Reeve) a subspecies of chinensis, again without distinguishing it from chinensis (s.s.).  We follow Smith (2000) subsuming malleata (Reeve) under chinensis (Gray) entirely.

  • Bellamya was mentioned parenthetically in my 29Oct03 essay on Invasive Viviparids in South Carolina. The distributional info is a bit obsolete, but there are several additional photos.
  • See my Bellamya News of 6Oct05 for items about Bellamya Ranching in North Carolina, Bellamya Roundup in Massachusetts, and Bellamya as a Model for Invertebrate Anatomy.
  • The Community Consequences of Bellamya Invasion in Wisconsin lakes were explored in my FWGNA blog post of 18Dec09.  There was also a nice photo comparing B. chinensis to B. japonica, both juvenile and adult.
  • My FWGNA blog post of 12Sept11, Dispatches from the Viviparid Front, included one item on a citizen's monitoring effort in Wisconsin (with links to some good references) and a second item on controlling B. chinensis in Ontario by hand-picking.
  • In Just Before The Bust (5Aug14) I described a Bellamya japonica population explosion in the tailwaters of the the Wateree Dam in central South Carolina.  That post featured several striking in situ photos, including a high resolution jpeg of a "bed" of Bellamya apparently filter feeding like mussels.
  • I reviewed the Bellamya ("Cipangopaludina") records in the USGS Nonindigenous Aquatic Species database in my post of 16Oct15, To Only Know Invasives.  That essay featured two photos of B. chinensis shells, one of which was incorrectly labeled japonica by the USGS.
  • Unsurprisingly, Bellamya of many species are widely retailed through the online aquarium trade.  See my post of 24Jan18, Snails by Mail.
