According to the mollusc’ density – 6.23 ind/m2 and biomass – 1,82 g/m2, C. fluminea is
in second place within all Bivalvia in the Cislita-Prut, after the native bivalve mollusc - Unio
tumidus (Philipsson, 1788) – 16 ind/m2 and 530 g/m2. Considering that Corbicula sp. is able to
bury into the substratum up to 45cm, their density may be more than the above mentioned
(Son 2007b).
