First record of the spiny-cheek crayfish Orconectes limosus (Rafinesque, 1817) (Crustacea: Decapoda: Cambaridae) in Romania.

Until recently, no invasive crayfish species have been reported in Romania. This is the first record of the cambarid species Orconectes limosus on Romanian territory; years after the countries on the upstream stretch of the Danube River reported the presence of the species on their territories. Monitoring activities in the area where the Danube enters Romania show that the extent of the invasion is currently relatively low; the species has been found on 55 of the 1073 km that comprise the Romanian sector of the Danube River.
