The Black Sea being one of the largest enclosed seas, has been subjected to severe ecological changes within the last few decades. The river induced nutrient enrichment and eutrophication caused significant changes in the species composition. Some of species have disappeared while some others were newly introduced and became dominant in the Black Sea ecosystem. Among those which dominated the pelagic ecosystem, gelatinous organisms suddenly attained a high level of biomass in 1989, which can hardly be supported by the existing trophodynamic structure.
