The impact of the introduced ctenophore Beroe ovata on its prey Mnemiopsis leidyi population, another invader ctenophore voraciously feeding on mesozooplankton, and consequently on the mesozooplankton community, was evaluated by undertaking both laboratory and field studies in Sevastopol Bay. Effect of food conditions (food concentration, volume of the experimental bottles) on ingestion, clearance rate, and digestion time and growth rate as well has been studied. The annual and inter-annual dynamics of both ctenophore populations have been studied for 5 years after Beroe arrival. It was shown the B. ovata bloom during the peak M. leidyi biomass resulted in the M. leidyi biomass sharply falling to extremely low values. The predatory impact o...
