Aquatic molluscs of the Elbe River between Němčice (near Pardubice, Eastern Bohemia, Czech Republic) and Hřensko (Northern Bohemia, Czech Republic) at 27 localities were investigated from 1994 to 2004. Altogether 40 species (24 gastropods, 16 bivalves) from 77 species known on the territory of the Czech Republic were found at sites under study. A gradual invasion of 6 non-native species (Potamopyrgus antipodarum, Physella acuta, Menetus dilatatus, Ferrissia clessiniana, Corbicula fluminea) and an extinction of another species (Theodoxus fluviatilis, Planorbis carinatus, Unio crassus, Pisidium amnicum) were documented in comparison with historical records. Rare mussel Pseudanodonta complanata and rare pea mussel Pisidium moitessierianum were found at several localities under study and these finds document survival of these bivalves in the Elbe River. Molluscan communities of particular localities were most often usually compounded from species Viviparus viviparus (downstream of loc. 9), Bithynia tentaculata, Radix auricularia, Radix ampla, Unio pictorum, Anodonta anatina, Corbicula fluminea (downstream of loc. 8), Sphaerium rivicola (downstream of loc. 7), Sphaerium corneum s. lat., Pisidium supinum, Dreissena polymorpha.

This paper brings a review of a malacological survey of the Slapy Reservoir (Central Bohemia, Czech Republic). This dam water reservoir was built in 1957 on the Vltava River with area 1392 ha, length 44 km, max. deepness 58 m and altitude 270.6 m. Aquatic molluscs at 22 sites were studied from 2005 to 2006. Altogether, 30 species of aquatic molluscs (21 gastropods, 9 bivalves) which represent nearly 40% of the total Czech aquatic mollusc fauna were found despite the absence of littoral vegetation. Bithynia tentaculata, Radix auricularia, R. cf. ampla, Gyraulus albus, Hippeutis complanatus, Sphaerium corneum, Anodonta anatina and surprisingly also vulnerable Anodonta cygnea belong to most frequent molluscs found during this research. Record of near threatened gastropod Viviparus viviparus fill in long gap among its occurrence in the Vltava River downstream of the Slapy Reservoir (last of the dam water reservoirs on the Vltava River) and in tributaries of the Vltava River in Southern Bohemia (Lužnice, Nežárka). Occurrence of four non-native species (Potamopyrgus antipodarum, Physella acuta, Menetus dilatatus, Ferrissia fragilis) were documented.

This paper completes knowledge on aquatic molluscs of the free flowing part of the Elbe River between Hřensko and the weir with lock in Ústí nad Labem – Střekov. Altogether, 21 species of aquatic molluscs (9 gastropods, 12 bivalves) were found in 2009. Viviparus viviparus, Potamopyrgus antipodarum, Bithynia tentaculata, Ancylus fluviatilis, Unio pictorum, Anodonta anatina, Corbicula fluminea, Sphaerium corneum and Pisidium supinum were the most frequently occurring molluscs found during this research. The occurrence of two endangered bivalves Pseudanodonta complanata and Pisidium moitessierianum was recorded. No significant difference from the previous author’s research was found. Molluscan communities of this part of the river were compared with those of the upper canalized part of the Elbe River which contain more species (especially gastropods) living predominantly in stagnant or slowly flowing waters e. g. Stagnicola palustris, S. corvus, Lymnaea stagnalis, Planorbis planorbis, Bathyomphalus contortus, Anisus vortex, Hippeutis complanatus, Ferrissia fragilis.

The record of the North-American gastropod Menetus dilatatus in the Southern Bohemia is mentioned in this paper. This finding is more than 80 km distant from known localities in the Elbe River Lowland and is the first one in the Southern Bohemia. This species was found in the mapping field for faunistic grid mapping No. 6551 (see Fig. 1) in the Otava River in the Orlík Dam Lake by diving in the water depth of ca. 2 m.

Menetus dilatatus (Gould, 1841) has been found in July 2005 in the Lipno Reservoir (Bohemian Forest = Šumava Mts., Southern Bohemia, Czech Republic) at 12 particular sites. This locality is about 80 km south of the nearest known locality of Menetus dilatatus and more than 160 km south of the Elbe Lowland where Menetus dilatatus occurs in many sites including the Elbe River. The altitude of the Lipno Reservoir reaches 725 m a.s.l. and is the highest known altitude of Menetus dilatatus in the Czech Republic.

Ornamental Species

Ornamental aquaculture is one of the main sources of non-native species worldwide. Unintentionally transported “hitchhiking” organisms have been previously recorded; although most of these species are transported from tropical regions, here we report on the first accidental transport of the zebra mussel (Dreissena polymorpha) in a shipment of ornamental Aegagropila linnaei (Chlorophyta) from Russia to the Czech Republic. This invasive mussel is listed on the national blacklist of alien species in the Czech Republic and can be easily released in outdoor garden ponds together with A. linnaei. Since the Czech Republic is known to be a gateway for aquatic ornamental species from a European perspective, re-export to other European countries is also possible. Thus, the spread of D. polymorpha via this pathway cannot be excluded. This finding should be of importance to conservationists, traders, decision-makers and other stakeholders.
