First record of the Amur goby Rhinogobius lindbergi Berg 1933 (Gobiidae) from the Tigris River drainage, Iran

Iran harbors a great faunistic diversity especially in freshwater fishes from different endorheic and exorheic basins with about 32 reported exotic fishes. Fishes are widely introduced and translocated aquatics due to anthropological activities. The present study reports first occurrence of the Amur goby, Rhinogobius lindbergi Berg 1933 (Gobiidae), from the Gaveh River, a tributary of Sirvan River drainage and Eivashan River, a tributary of Kashkan River system. In addition, we present meristic and morphometric data of the specimens herein examined. The collected specimens probably introduced to the rivers along with other exotic species as accidental introduction. Therefore, an effective management strategy required to minimize their negative impacts.
