Present distribution and spreading modes of Invasive Listing Sources. Many native clams are declining as C. fluminea outcompetes them for food and space. 153-167.Counts, C.L III; Villalaz, J.R and Gomez, H.J.A., 2003. Scientists remain unsure about what barriers may act upon natural distributive efforts by these clams. The shells of the yellow morphs are straw yellow on the outside and white on the inside; those of brown morphs were dark brown and purple, respectively. C. fluminea is an inland water, filter-feeding bivalve native to southeast Asia but causing numerous problems in its new range of distribution in the Americas, Europe and Australia. C. fluminea requires well-oxygenated waters and prefers fine, clean sand, clay, and coarse sand substrates. The Global Invasive Species Database was developed and is managed by the Copyright: CC BY

Biological Invasions. Since this first introduction, it is now found in 38 states and the District of Columbia. Many native clams are declining as C. fluminea outcompetes them for food and space. Bulletin de L Institut Royal des Sciences Naturelles de Belgique Biologie. Corbicula fluminea is a freshwater clam that has caused millions of dollars worth of damage to intake pipes used by power, water, and other industries. Not much is known about the Asian clam or the possible threat of disrupting native ecosystems. The Asiatic clam Corbicula (Bivalvia: Corbiculidae) in Belgium. Longitudinal distribution of molluscan communities in the Rio de la Plata estuary as indicators of environmental conditions. Used as live bait throughout the United States. Due to their current ubiquity, that task has proved difficult. Müller, 1774) Categories. ... Subject: Corbicula fluminea (O.F. Wildlife - Snails, Slugs, and Mussels. A field trial was carried out to test the respective efficacy of three different mechanical dredge methods Population dynamics of the asiatic clam, Swinnen, F; Leynen, M; Sablon, R; Duvivier, L and Vanmaele, R., 1998. 4(1-2). All Rights Reserved The life span is between one to seven years. C. fluminea requires well-oxygenated waters and prefers fine, clean sand, clay, and coarse sand substrates. Asian clam (English), prosperity clam (English), Asiatic clam (English) Larvae spawned late in spring and early summer can reach sexual maturity by the next fall (Aguirre and Poss 1999). Malacological Review. Dominance of the Asiatic clam, Morgan, D.E; Kesar, M; Swenarton, J.T and Foertch, J.F., 2003. 47-53.Vincent, T and Brancotte, V., 2002. That is, the clam has become widely distributed by relying upon humans as an agent of dispersal. Many states are installing screens over intake pipes to power plants or man-made lakes in hopes to prevent the larvae from entering their waterways.Nichols, Frederic, Janet Thompson, and Laurence Schemel. Corbiculidae in the Pantanal: History of invasion in southeast and central South America and biometrical data.


The term invasive species refers to a subset of those species defined as introduced species. State List - This map identifies those states that list this species on their invasive species list or law.

While this may seem to be a positive solution, the clam could potentially be a vector for exotic parasites or diseases that could then infect native species.Unlike most of the other invasive species in the US, the Asian clam is not able to rapidly distribute itself. 68(0). 1-12.Darrigan, G., 2002. Therefore, it is difficult to predict the range of the clam in the future.

Their results indicate that several local fish species have modified their diet to … Currently, many organizations are struggling to find a way to prevent the spread of Asian clams. (Supplement 8). Potential impact of filter-feeding invaders on temperate inland freshwater environments. The invasive Asian clam Corbicula fluminea (Müller, 1774) has established a high density and self-sustaining population within the tidal reaches of the River Barrow, Ireland. For more information, visit Invasive.org. Corbicula fluminea is a freshwater clam that has caused millions of dollars worth of damage to intake pipes used by power, water, and other industries. C. fluminea spreads when it is attached to boats or carried in ballast water, used as bait, sold through the aquarium trade and carried with water currents. If a species has been introduced, but remains local, and is not problematic for human industry or the local biodiversity, then it is not considered invasive, and does not belong on this list. Occurrence of Darrigan, G., 1999.
