Sažetak
This review has underlined a significant number of new fish species new to the Adriatic Sea. At least 34 new species became a new elements of the Adriatic ichthyofauna representing 24 family (of which 10 are new for the Adriatic: Hemiramphidae, Leiognathidae, Haemulidae, Siganiidae, Ipnopidae, Zoarcidae, Monacanthidae, Cylopteridae, Terapontidae, Fistularidae) and increasing the number of fish recorded in the Adriatic to 447. This has been attributed in part to the increased prospection activity, coupled with new, recently adopted techniques which allow access to previously inaccessible habitats, and observation in vivo. It is also clear, however, that this increase is also attributable to real changes in population dynamics during this period. The most relevant is the fact that the increase in number of species correlates clearly with interannual shifts in climatic and oceanographic processes. The impact of other potential factors is less well understood at present, but it is also likely that biological invasion (eleven lessepsian migrants have reached Adriatic up to date), overfishing by humans, and the consequent changes in the food chain equilibrium, have a significant impact on fish populations and diversity over the last few decades.
