Vodní měkkýši přehradní nádrže Slapy (Česká republika)
Aquatic molluscs of the Slapy Reservoir (Czech Republic)
Luboš Beran
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.
