Sažetak
Fish community changes are mainly evident in the Mediterranean basin considered one of the main hotspots of marine bioinvasion on the planet. This is partly due to many fish species reached he Mediterranean Sea after the opening of the Suez Canal, while other newcomers arrived through the Gibraltar Strait. Continuous arrival of new species has been confirmed, although in less uantity, in the Adriatic Sea. The first sighting of the Lagocephalus sceleratus for the Adriatic Sea was in 2012. Since then, 7 additional specimens have been recorded (TL range 478-663 mm) on the eastern Adriatic coast. One specimen (TL=587 mm) was caught on the western coast (Puglia, Italy). Although there is no strong evidence of a permanent population in the study area, these aptures are an indication of an expansion of the distribution of the silver-cheeked toadfish in recent years in the Adriatic Sea. It has probably extended its distribution from populations stablished in the Ionian Sea. The first record of the Siganus luridus was in the northern Adriatic Sea in 2010. A second record occurred in the eastern Adriatic in the very same year. uveniles were observed for the first time in the same area in 2011. Three years later, one specimen was caught on Montenegrin coast. Last records in 2016 were in the area of southern Adriatic howing a presence of large schools of this species clearly indicating an established population in the area. Fistularia commersonii was recorded in the Adriatic Sea for the first time in 2006 in the southern Adriatic. There are also new additional records in Montenegro in 2008 and the Island of Šipan (two juvenile specimens) in 2011. Based on additional records of juveniles, the existence of a self-sustaining population in the Adriatic is possible.
