Wave dynamics of open-sea ecosystems ("impact waves'') have been considered under conditions of inhomogeneous hydrophysical fields. The effects of inhomogeneity of different types on the possibility of impact wave stopping (localization) was studied. Concentrated inhomogeneity in certain parameters affecting the life span of individuals in the population (water salinity and temperature) may cause wave localization. Otherwise, inhomogeneity in the field of current and turbulence leads only to waveform distortion and wave rate change. Inhomogeneity of the ecosystem parameters may also cause sharply inhomogeneous ("patchy'') spatial distribution of the population.
