Abstract
We analyzed the state of pelagic ecosystem of northeastern Black Sea affected by invasion of a new settler Beroe ovata in 1999–2001. Development of B. ovata considerably decreased the population of another invader, Mnemiopsis leidyi, that deformed the Black Sea ecosystem for over a decade. Reduction of M. leidyi population limited its influence on the ecosystem and, consequently, we observed recovering of the main components of the Black Sea pelagic ecosystem—zooplankton and fish as well as their eggs and larvae. The relationships between annual and seasonal variability of the population development and size of the both invaders M. leidyi and B. ovata are discussed.
