ABSTRACT

The article presents data about the new finding of the sea zander Sander marinus in the Dnieper-Bug estuary. Morphological analysis of characters of three zander species showed that à specimen caught on 21 September 2016 in the Dnieper-Bug estuary belongs to Sander marinus (Cuvier, 1828). Meristic and plastic features also were analyzed. Among them the most important for differentiation of sympatric species of zanders were selected. Based on the results of data analysis we can conclude that the sea zander is actually not completely extinñt, but only neglected in the analysis of commercial catches as the Red Book species, which is strictly forbidden for fishing.
