PRAWN <i>PALAEMON MACRODACTYLUS</i> (DECAPODA, PALAEMONIDAE) IN THE DON RIVER DELTA
The first cases of the oriental prawn <i>Palaemon macrodactylus</i> Rathbun, 1902 capture in the Don delta and the eastern part of the Taganrog Bay are described. The first 9 prawns were registered in August 2016, and 2 more prawns were registered in October 2019. Sexually mature specimens were found on sandy and silty soils with water salinity from 0.58 to 5.0‰. The presence of a stable population of <i>P. macrodactylus</i> in the investigated region substantially extends the range of this species in the Azov-Black Sea basin.
