Living individuals of Asian clam Corbicula fluminea (Müller, 1774) (Bivalvia: Veneroida: Sphaeriacea: Corbiculidae) have been recorded for the first time in the Republic of Moldova (Prut River basin, November 2009). Perhaps, this invasive species entered the Prut River basin from the Romanian or Ukrainian territories, where this species was previously recorded. This invasive species may negatively influence the native bivalves as they are in competition for both nutrient resources and substrate.
The invasive mollusc was found in the riverbed
on the muddy bottom substrate at depths up to
1м. More than 100 living individuals were found
with lengths of 3-19 mm along a transect
0.7×25m.
