Salmo obtusirostris

Adriatic trout ( Salmo obtusirostris ) from the Neretva

The Adriatic trout ( Salmo obtusirostris ) is a species of the genus Salmo in the family of salmon (Salmonidae ).

Description

The Adriatic trout was found to be Salmothymus obtusirostis by many authors in a separate genus. This classification is valid on the basis of phylogenetic studies as outdated ..

Compared to trout ( Salmo trutta ) it has a very short head with a blunt snout. The caudal fin is much more indented. The fish is usually not more than 50 inches long and has a relatively stocky body. The largest known specimen reached a length of 70 centimeters. The upper jaw is very broad and short, the dentition weak. In the coloring this kind of brown trout ( Salmo trutta fario ) is similar.

Occurrence

The non-migratory freshwater fish is limited to rivers in the karst areas in the Dinaric Mountains. As a subspecies have been described: Salmo obtusirostris oxyrhyncus Steindachner, 1882 from the Neretva river and its tributaries Buna in Bosnia and Herzegovina and Vrljika in Croatia, Salmo obtusirostris Salonitana Karaman, 1927 from the Jadro, Salmo obtusirostris krkensis Karaman, 1927, from the Krka in Croatia and Salmo obtusirostris zetensis ( Hadzisce, 1960) from the Zeta in Montenegro. The validity of these taxa is uncertain.

In all parts of its range, which is composed only about 500 square kilometers, the Adriatic trout by dams, often illegal overfishing and hybridization is endangered by introduced trout.
