Asian Clam
Corbicula fluminea
Summary 5
Corbicula fluminea is a species of freshwater clam, an aquatic bivalve mollusk in the family Corbiculidae.
Food habits 6
The Asiatic clam is a filter-feeding bivalve. It filters microscopic organisms, such as plankton, from the water.
Habitat 7
Habitat Type: Freshwater
Comments: This species can survive in almost any freshwater environment, including brackish and estuarine waters, that is permanent (Carlton, 1992). In a study of the relationships of 12 environmental variables to density oand biomass of Corbicula fluminea, higher density and biomass were found to be correlated to where substrate was > 40% fine sand, < 45% silt, and < 8% organic content (Cooper, 2007).
Range description 8
The species is native to southern and eastern Asia (eastern Russia, Thailand, Philippines, China, Taiwan, Korea, and Japan) but has been very widely introduced. This species has been introduced to several parts of Africa, North America and throughout Europe and the Mediterranean. It is considered one of the worst invaders of aquatic ecosystems. Brandt (1974) reported this species in Thailand from the Chao Praya River and some tributaries.
Reproduction 9
The Asiatic clam is hermaphroditic, with single genopores on each sides of the body. Reproduction and larval release occurs biannually in the spring and in the late summer. The clam is believed to practice self-fertilization, enabling rapid colony regeneration when colony populations are low.
