Salmo obtusirostris

Salmo obtusirostris is found naturally in four drainages of the Adriatic Sea, in Croatia, Bosnia and Herzegovina and Montenegro: the Neretva-Vrljika system, the Jadro, the Morača-Zeta system, and possibly the Krka river drainage around Knin although it is presumed extinct for some time now. The different populations are sometimes classified into subspecies: • Salmo obtusirostris oxyrhynchus: Neretva and its tributaries the Buna and its tributary Bunica, the Bregava, the Upperr and Lower Trebižat, and the Rama before construction of the Rama Dam, in Bosnia and Herzegovina; it also inhabit the Vrljika within both Croatia and Bosnia and Herzegovina. • Salmo obtusirostris salonitana: the Jadro River and the Žrnovnica River (introduced from the nearby Jadro in the 1960s) in Croatia; • Salmo obtusirostris krkensis: the Krka river (inhabited only about one kilometer of the river's headwater, but is now most likely extinct); in Croatia • Salmo obtusirostris zetensis: the Zeta River and the Morača River in Montenegro. ==Appearance and anatomy==

The most obvious characteristic of the Adriatic trout is an elongated snout. It also has a small and fleshy mouth, relatively large scales and high body depth. The color of the body varies between subspecies, it is mostly green with red and black dots. There are no vertical stripes that are common in brown trout of the Adriatic Sea drainages that can be found. ==Conservation==

Adriatic trout are threatened by excessive damming, hybridization with introduced species and overfishing. Adriatic trout prefers rivers with more water and wide riverbed. Adriatic and brown trout have different spawning times that overlap only slightly every few years, which is why natural hybridization is not widespread and both species live sympatrically in the same rivers. ==References==
