Status of juvenile ichthyofauna in the Kornati Archipelago (Adriatic Sea), after 25 years of National Park establishement

The Kornati Archipelago, constituted of 147 islands, islets and reefs, signalises itself by very special geomorfological properties and ecological conditions. Area is characterized by high biodiversity of flora (300 species) and fauna (350 species), geologic and geromorphologic phenomens, as well as arheologic heritage. The intensification of fishing and the progress of tourism have demanded a fast, effective protection and, therefore, Kornati National Park established on 24th July 1980. Data of ichthyofauna collected in the 1960-1992, on 141 localities consisted of 160 fish species and subspecies which make up 36.9% of total Adriatic ichthyofauna. 64 juvenile fish species were recorded during investigations in period from 1990 to 1992. Repeated sampling after 15 years resulted with records of 46 juvenile fish species. The missing ones (21 species) are rare species which were previousely represented only by one or two individuals while five of them were not recorded in last investigations. Moreover, one of them is tropical element showing that environmental changes have also impact on status of Kornati ichthyofauna. Detailed and permanent monitoring is required for completing a list of juvenile fish species and conservation of the Kornati Archipelago biodiversity.
