Journal Title: KULON - Year 2016, Vol 21, Issue
Abstract
Two empty shells of the Asian clam Corbicula fluminea were recorded on left bank of Vistula river in Warsaw (52°17’07”N, 20°59’42”E) on 29 June, 2016 (photo 4). Altogether, 19 paired and 76 single empty valves were collected during following surveys of left and right banks of the river and two oxbows within city limits in July and August 2016. A total of 8 live bivalves were collected from the river bed and the oxbow at the depth of about 40 cm. The largest empty shell was 31.6 mm wide and 29.1 mm long. The live specimens measured 9.4-22.5 mm in width and 8.3-25.2 mm in length. The records of the Asian clam Corbicula fluminea in Warsaw document spreading of this invasive species down the Vistula River from the upper part of the river.
