Invasiviteit (toelichting) C. fluminea is native to southern and eastern Asia. For this species the native region is usually defined as Thailand, Philippines, China, Taiwan, Korea, Japan, East Russia, Australia and parts of Africa. It was introduced to North America around 1924, probably by Asian immigrants who used it as a food source. Later it was also introduced to South America and Europe, first in the 1970s in Portugal in the Rivers Tagus and Minho (Mouthon, 1981). From there it spread eastward to Spain, France, the Netherlands, Switzerland, the UK and many other European countries (Bij de Vaate and Greijdanus-Klaas 1990, Korniushin 2004). In contrast to C. fluminalis, it is present in North America since 1924 (Counts 1986) where its reproductive success and dispersal has resulted in the most rapid expansions of any non-native species in North America. As in Europe there are two sympatric distributed species - C. fluminea and C. fluminalis - the invasiveness of both species is more or less the same, with similar sediment preferences, a wide variety of reproductive strategies, temperature and salinity range and similar ways of distribution (with ballast waters of ships, also inland waterways facilitate transfer of invasive alien species (see also with C. fluminalis).

  • Verspreiding in Nederland (toelichting) C. fluminea is known from the Netherlands since 1990. Bij de Vaate and Greijdanus-Klaas (1990) discovered that two seperate species seem to be involved, identified as C. fluminalis and C. fluminea (Gittenberger et al. 1989). C. fluminea is the more common of the two species, now distributed all over the Netherlands in fresh water habitats. The species can be locally very abundant.

  • Ecologische impact (toelichting) In the DAISIE project, C. fluminea is listed as one of the 100 worst invasive species. C. fluminea can alter benthic substrata and competes with native bivalves for food and space; it is more tolerant to polluted environments than native species of bivalves; its filter feeding may result in a significant removal of suspended matter from the water, and a decrease in phytoplankton and seston; it may also increase the rate of sedimentation (Cabi 2012). In the Netherlands there is as yet no evidence this is directly responsible for declines in populations of native species by outcompeting them for space or resources.
    Economische impact (toelichting) The economic impact of C. fluminea could be high. In the USA the species causes millions of dollars worth of damage. Because of the high densities of specimens, alive as well as dead, they clog water intake pipes. Several nuclear reactors had to be closed down temporarily for the removal of large quantities from the cooling systems (Isom 1986). In Europe both species of Corbicula are not considered a pest, neither in other European countries nor in the Netherlands.
