Presence of Lessepsian fish migrants in the Adriatic Sea: A brief overview

The "Lessepsian migration" is the largest marine biological invasion in the world. Hundreds of species have already passed the Suez Canal and settled in the Eastern Mediterranean Sea. The marine biodiversity of the Mediterranean Sea is nowadays facing substantial the structural changes in flora and fauna. Such changes were also recorded in the Adriatic Sea, as well. During the last few decades, various factors including 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 in this area. Among these, 13 Lessepsian fish migrants were recorded in the Adriatic sea: Pampus argenteus, , Saurida lessepsianus , Sphyraena chrysotaenia, Epinephelus coioides, Leiognathus klunzingeri, Stephanolepis diaspros, Siganus rivulatus. Terapon theraps, Fistularia comerssonii, Lagocephalus sceleratus, Abudefduf saxatilis, Abudefduf sp., Bregmaceros nectabanus and Pterois miles. Two species (Paraexocoetus mento and Hemiramphus far) were excluded from the previous lists because the records were not scientifically confirmed, while three species F. commersonii, L. sceleratus and S. luridus proved to be successful invaders especially in its southern part. The situation with the records of species of the genus Abudefduf is particularly interesting and should be discussed. The lionfish P. miles was observed on four locations: Santa Cesarea Terme (Lecce, Italy), Torre Canne-Fasano (Brindisi, Italy), Dherme beach (Albania) and Komiža, island Vis (Croatia).
