Zusammenfassung:From September 1999 till September 2003 the studies of species composition, abundance and biomass of fodder and gelatinous (Beroe ovata и Mnemiopsis leidyi) zooplankton were carried out at permanent station near the outlet of Sevastopol Bay. Seasonal dynamics of fodder zooplankton biomass was characterized by summer-autumn and winter maximum values (up to 2.4 g/m2). Meroplankton and copepods constituted 42.8±4.0 and 32.0±3.4% of annual total fodder zooplankton biomass, respectively. After the appearance of predator ctenophore B. ovata in Sevastopol Bay, mean annual biomass of M. leidyi decreased 3.5 times in comparison with 1995, the duration of M. leidyi impact on zooplankton community reduced. As a result, the abundance of copepods and meroplankton significantly increased indicating recovering processes in the ecosystem.
