First Record of Crangon crangon (Decapoda, Crangonidae) in the Taganrog Bay

Salinization and increasing temperatures of the waters of the Sea of Azov and the Taganrog Bay itself in recent years have led to the spread of adventitious species in this basin. At the end of May 2024, in the eastern part of the bay, not far from the city of Mariupol (46°54′11″ N, 37°47′12″ E), a Crangon crangon (Linnaeus 1758) was found in the catch of a trap venter at a depth of 7.5 m at a salinity of 13.6% at the bottom. Previously, these shrimps had not been found in the northern part of the Sea of Azov or in the Taganrog Bay. This species, the only one from the Crangonidae family recorded in the Black Sea, lives in the Kerch Strait and in the southern part of the Sea of Azov. It can be assumed that, owing to changes in environmental conditions, the range of the shrimp shifted to the north of the Sea of Azov with penetration into the western part of the Taganrog Bay.
