Description

Habitat

Ecology: This species primarily inhabits closed off and small waters such as ponds and peatlands, but can also be found occupying lakes and slow-flowing lowland rivers (Zettler et al. 2006). It is also found in canals, drainage dykes and dam reservoirs (Killeen et al. 2004). The species appears to prefer waterbodies characterised by high concentrations of dissolved oxygen (a likely consequence of the species' fast growth and large size), free from floating vegetation and with fertile bottom sediments (Zaj?c 2002, Rosi?ska et al. 2008). The species is intolerant of poor enivironmental conditions, and can be used as a bioindicator of clean water (Rosi?ska et al. 2008). When present, it is often the only mussel species inhabiting these areas (Zettler et al. 2006).[1].
