ABSTRAKT

Data about invasion of the different invertebrates and Actinopterygian fish species into the surface water bodies of Ukraine and outside its territory, as well as material on spreading of the autochthonous species in the inland water bodies have been generalized. The critical analysis of the results of introduction and acclimatization of the valuable allochthonous species in the water bodies is given. Differentiation of the invasive invertebrates and Actinopterygian fish species of Ukraine into three groups according their adaptation potential has been suggested.
