Última The occurrence of the Asian Clam Corbicula fluminea in the lowe amazon basin Acta Amazonica BEASLEY,Colin Robert; TAGLIARO,Claudia Helena; FIGUEIREDO,Wilsea Batista. This paper records for the first time the presence of Corbicula fluminea (Philipi, 1844) in the Brazilian Amazon Basin. This exotic bivalve was found in localities on the Amazonas, Pará and Tocantins rivers. Density and population size structure were measured in some localities. Mean density is between 6.66 and 7.3 individuals m-2. Population size structure and the dates of the first records suggest that the introductions may have occurred between 1997 and 1998. The introductions may have been mediated by ocean-going vessels visiting the ports of Manaus and Belém. The potential impact of the invasion on native freshwater bivalves is discussed along with the need for monitoring and prevention of further introductions of non-indigenous bivalves in Brazil.
