Abstract
The freshwater molluscs of the Some?/Szamos rivers have poorly been studied so far; only a few species and sampling points were mentioned in the last 150 years. The authors have found 22 mollusc species, and pointed out the disappearance of three species, namely Theodoxus transversaHs (probably extinct from the whole Transylvania), Bithynia leachi and Unio pictorum. Most of the species have a patched distribution along the river, due to pollution and hydrotechnical works. On the basis of the present-day areas of some species, especially that of the family Unionidae, we have ranked the ecological state of the river sections.
