State of populations of Bivalve Mollusks of the families Unionidae and Pisidiidae (Mollusca: Bivalvia) in Sluch River basin
in the conditions of exacerbation of the ecological situation. Shevchuk L., Bylyna L., Bitner D.
At the beginning of 2000-s Sluch River was considered to be one of the purest rivers in Zhytomyr Region, delivering its waters into
Prypiat River being treated as one of the largest rivers in Ukraine and the largest right Dnipro River tributary. The transboundary status
of Sluch River flowing in the territory of two countries (Ukraine and Belarus) provokes substantial interest to the river. The results
of the research devoted to the bivalve mollusks in Sluch River basin obtained in 2007?2013 proved its good ecological condition. It
was here the bivalves? settlement was marked by the richest species diversity among all water bodies of Ukraine. The general condition
of the Unionidae turned out to be one of the best in Ukraine. Recent years have significantly aggravated the situation. The previous
collection of the material held in summer 2019 allow for stating that the situation with the Unionidae settlements has gone worse,
that witnesses the general aggravation of ecological situation in Sluch River basin. These mollusks were found in 63% of locations
under research typical for the species existence. There were no mollusk settlements consisting of six or five species identified in
collection locations. P. complanata was not found in any location, while this species is recommended for being registered in the Red
Book of Ukraine and is under protection in six countries in Europe. Mollusks of the family Pisidiidae (Molusca: Bivalvia), also being
the indicating species, due to their small size do not play a key role in the process of self-cleaning of natural reservoirs, but interest in
this group of animals is growing. In Ukraine, mollusks of the Pisidiidae family are represented by three genera: Sphaerium, Musculium,
Euglesa. During research in the summer of 2019, five species of mollusks of the genus Sphaerium were found: S. corneum (Linnaeus,
1758), S. nucleus (Studer, 1820), S. solidum (Normand, 1844), S. rivicola (Lamarck , 1818), S. nitidum (Clessin, 1876). The obtained
information can state only low density of bivalve molluscs (Mollusca, Bivalvia). Key words: bivalve mollusks (Mollusca, Bivalvia),
Unionidae, Pisidiidae, condition settlements, Sluch river basin.
