Stwierdzenie Corbicula fluminea (O.F. Muller, 1774)(Veneroida: Corbiculidae) w środkowej Wiśle
Journal Title: KULON - Year 2017, Vol 22, Issue
Abstract
On 19 September 2016, the shells of the Asian freshwater clam Corbicula fluminea were recorded at three sites on the left bank of the Vistula River upstream, near Warsaw. The studied sites were located near Kępa Zawadowska (52O08’53.4”N 21O09’15,2”E), the mouth of the Jeziorka (52O07’21.9”N 21O10’30.0”E) and Dębina (52O06’02.9”N 21O12’16,4”E) rivers. In 2017, three following sites were documented near Przydworzyce (51O43’08,7’’N, 21O24’48,6’’E), Wilczkowice Górne (51O40’52,5’’N, 21O27’41,5’E) and at the mouth of the warm-water discharge canal of the Kozienice power plant (51O40’05,4’’N, 21O28’05,5’’E) (& g.). % e shells near Przydworzyce were found at the distance of 981 m from the Vistula bank that indicates that birds, like the Hooded Crow Corvus corone, may have carried them to that place. All these records show that the Asian freshwater clam occurs over a considerable length of the Middle Vistula River and may probably indicate an advanced stage of the invasion of this species in the central part of Poland. It is highly recommended to carry out the survey on possible expansion of the species along the Vistula River and its tributaries in the nearest future.
