Abstract

Bivalve marine mollusc Barnea candida (= Pholas candidus) from Pholadidae family is sensitive to the high concentration of organic matter in sea water and recently has been included into the list of indicator species for the Black Sea (Alexandrov, Zaitsev, 2016). Its recording in Ukrainian part of the Danube Delta aft er more than 60 years since its first registration is probably the evidence of reduction of eutrophication and gradual restoration of local aquatic ecosystem biodiversity.
