The introduction of the fish from the Danube area into the Mediterranean Vransko lake, Croatia

The Vransko lake is a fresh-water lake in southern Croatia only one kilometer away from the Adriatic Sea. This is an oligotrophic lake with mild climate. At first the only fish species that inhabited the lake was eel (Anguilla anguilla), from the underwater karsts caves. After 1895, when the artificial channel was dug, marine euryhaline fish species sporadically migrated to the lake. In the late forties the common carp (Cyprinus carpio) from the north Croatia was introduced. Up to the mid-fifties, mostly accidentaly, several other fresh-water species were also introduced. During more than 50 years of existence in the Vransko lake common carp adapted well to its conditions and developed into its wild, elongated and scaled form. The original idea of introducing common carp for commercial fisheries was never realized. Nevertheless, the angling of the carps nowadays attracts many tourists who visit the Adriatic coast or camp by the lake
