Abstract

The structure and composition of Mediterranean biodiversity has changed significantly. So
far, in Montenegrin coastal waters, nine new non-native species have been recorded: Tylosurus
acus imperialis, Caranx crysos, Siganus luridus, Fistularia commersonii, Stephanolepis diaspros,
Sphoeroides pachygaster, Lagocephalus sceleratus, Callinectes sapidus and Farfantepanaeus
aztecus. Allochthonous species are starting to compete for food and space and leading to habitat
degradation, socio-economic impacts and can hybridise with the native species. Natural factors
and human activities have enabled the arrival of non-native species into the Adriatic Sea. Four
of the species are Lessepsian immigrants, which arrived via the Suez Canal, but five others were
introduced from the Atlantic Ocean, through the Strait of Gibraltar. Analysis using the Marine Fish
Invasiveness Screening Kit (MFISK), Aquatic Invasiveness Screening Kit (AS-ISK) and Receiver
operating characteristic (ROC) showed a calibration threshold of 22.5 for MFISK, a BRA (Basic
Risk Assessment) score of 34 and a CCA (Climate Change Assessment) score of 46. A measure of
the accuracy of the calibration analysis is the area under the ROC curve (AUC). Two species were
characterised as non-invasive: Tylosurus acus imperialis and Caranx crysos, but five others were
characterised as invasive and covered by the categories from moderate to high-risk.
