title: Долговременные изменения популяции двустворчатого моллюска-вселенца Anadara kagoshimensis на северо-восточном побережье Чёрного моря
abstract: The distribution, abundance and biomass of an invasive blood ark Anadara kagoshimensis (Bivalvia) were investigated on the northeastern coast of the Black Sea (from the Kerch Strait to Adler) in 2001 and 2012. The occurrence of this species and habitat depth range (10–65 m) did not change within the 12 years. In both surveys maximum abundance and biomass were registered at 20–35 m depth of. In shallow water near the Kerch Strait species abundance and biomass were similar in 2001 and 2012. Howeve
