| Özet |
| In recent decades the numbers of alien species and their introduction rate to aquatic systems have been increasing over the world. Most extend biodiversity of the system and most of them don’t have negative influence on its functioning. Only some of them can attain massive occurrence, suppressing or totally replacing the native species due to food competition and consumption. As a result the community structure is simplified, tolerance to external impact decreases and the system becomes open to injury. Ability to successful invasion of alien species, along with other factors, is determined with their ecologicalphysiological features. The characteristics of these species are short life cycle, high fecundity and growth rate, earlier maturation, wide food spectrum, eurybiotics and high tolerance to pollution.The North Atlantic ctenophore Mnemiopsis leidyi Agassiz A., 1865 (Ctenophora, Lobata) introduction of which caused real catastrophe in the Sea of Azov and the Black Sea in the late 80-s, have the most of these traits. The consequence of introduction of this species was changing of energy pathway in the plankton pelagic system (Vinogradov et al., 1989; Shushkina et al. 1990; Shushkina and Vinogradov, 1991; Kideys, 1994). Instead of the trophic chain “Zooplankton-planktivorous fish” the energy flow has been directed to “zoöplankton-M. leidyF chain that resulted in fishery collapse and great economic damage of the Black Sea countries. M. leidyi invasion has brought to reconstruction of the structure and functioning of different food levels of the Black Sea |
