title: Interannual Population Dynamics of the Ctenophore Beroe ovata Bruguière, 1789 at the Outer Shelf of Sevastopol Bay of the Black Sea
abstract: On the basis of the results of cruises and long-term monitoring at the outer shelf of Sevastopol Bay, the interannual dynamics of the state of the population of the alien ctenophore Beroe ovata in the Black Sea for 2000–2021 was analyzed.
