The huge mussels, reaching 22 to 26 cms. in size which appeared along the bank of the Danube in Rousse about a fortnight ago, have been proved to be an invasive mussel species from China, Radio Varna reports.
Biodiversity and ecosystems experts from the Bulgarian Academy of Sciences say they are Chinese pond mussels. They were first spotted in the Danube in 2005 but since then, the population of the species has exploded.
