Abstract
Results of monitoring investigations over the past 10 years are presented concerning the distribution of a new species-invader in the Caspian Sea, Mnemiopsis leidyi. The spatial distribution of its population is shown during the period of its maximal development in August-September. The influence of that gelatinous invader on different levels of the trophic pyramid is described to show the cause of qualitative and quantitative decline in the nutritive base both of plankton feeders (Caspian kilka, shads) and mollusk-eating fish (roach, sea bream and common carp), to estimate the level and reveal the trend of ecosystem development in the Caspian Sea in the near future.
