Sažetak
The marine biodiversity of the Mediterranean Sea is nowadays facing substantial structural changes in flora and fauna. Such changes were recorded in the Adriatic Sea, as well. During the last few decades, various factors such as climate change, anthropogenic activity and „lessepsian migration“ have altered the composition of Adriatic ichthyofauna. Extensive investigations carried out in the last decades allowed us to recognize species previously not recorded or reported from this area. Majority of alien fish species recorded in the Adriatic Sea are lessepsian migrants of Indo-Pacific origin. Out of 14 recorded lessepsian fishes, Lagocephalus sceleratus, Fistularia commersonii and Siganus luridus were the only species recorded multiple times and with geographically scattered records suggesting successful invasion. The common lionfish Pterois miles is showing a rapid geographical expansion in the Mediterranean Sea since 2012. The recent record of this species from Sicily could be a warning sign for the Adriatic Sea. Even if the current abundances of P. miles are still below the threshold of a “true invasion” there is an urgent need to take action and to promote control measures. The impact of successful colonizators on the native communities in the Adriatic Sea is unknown yet. However, the relatively fast pace of the invasions suggest that their effects may become relevant in the near future.
