NEW DATA ON THE DISTRIBUTION OF Cottus gobio(SCORPENIFORMES; COTTIDAE) IN CROATIA WITH SPECIAL OVERVIEW OF THE ADRIATIC BASIN

In this paper, the data already known on the distribution of C. gobio in Croatia and is enriched and plotted together with several new localities. In the Buti nica River, right tributary of the Krka River, and the Babi a Lake, one new population of Cottus gobio Linnaeus, 1758 was recorded during August 2009. This population belongs to the Adriatic lineage of C. gobio, which was until recently considered a separate species - C. ferrugineus Heckel and Kner, 1895. This lineage also includes the population from the River Zrmanja, and supports the theory that the Krka and the Zrmanja were connceted in the past. So, the distribution area of Cottus gobio has been considerably extended by this study to the North, South and East of Croatia.
