PRAWN <i>PALAEMON MACRODACTYLUS</i> (DECAPODA, PALAEMONIDAE) IN THE DON RIVER DELTA
The first cases of the oriental prawn Palaemon macrodactylus 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 P. macrodactylus in the investigated region substantially extends the range of this species in the Azov-Black Sea basin.
