Abstract

The integrated analysis of the variability of abiotic and biotic components in South-Eastern Baltic (Gdansk Basin as an example) over the past few decades (1974–2010), testified significant changes in the ecosystem of the sea. Salinity factor in this aspect has played a major role in the significant reduction in the spawning grounds of cod on the one hand, on the other, along with the increase of water temperature determined the dominance of sprat and herring in the ecosystem of the Baltic Sea.
