Abstract


The aim of our research was to study the current state of ichthyofauna of the Tiligulskiy Estuary and to provide the scientific background to improve the functioning of the fishing connecting channel. The modern ichthyofauna of the Tiligulskiy lyman includes 24 fish species from 18 genera and 11 families. Only 9 of them (Mediterranean species) are widespread in the estuary at present time. We suggested that the dynamics of species composition depends of the salinity of estuarine water. The basis of modern catches consists of Sand smelt (up to 90%) and gobies. The catch of mullet (predominantly Golden grey mullet and Red-lip mullet), anchovy, and European flounder is rather insignificant. The increase of migratory fish species catches is possible when operating fishing connecting channel would be equipped in accordance with fishery recommendations.
