Notes on Taxonomy and Nomenclature

Top of page
In the attempt to end ecomorphotype confusion in the Asia range, Morton (1986) recognizes only two species: Corbicula fluminea a freshwater species and all estuarine dioceous non-brooding species as C. fluminalis. However, this division was refuted when several phylogenetic studies showed clear differences among species (Hillis and Patton, 1982; Hatsumi et al., 1995; Lee and Kim, 1997; Renard et al., 2000; Siripattrawan et al., 2000).

Notes on Natural Enemies

Top of page

A review by Sickel (1986) lists 14 fish species, 13 duck species, raccoons, crayfish and flatworms are listed as natural predators. In a more recent survey in South America, García and Protogino (2005) recognize C. fluminea as a food source in eight fish species by clam’s presence in their guts.

Gaps in Knowledge/Research Needs

Top of page

In addition to the studies of Hedtke et al. (2008) it is suggested there should be a worldwide database for multiple androgenic lineages of Corbicula. Also it is recommended to create a phylogeny of Corbicula using single copy genes because of unexpected polyphyly in androgenic lineages. The rRNA genes are suggested by Hedtke et al. (2008) due to their conservative characteristics within the eukaryotes.
