The Adriatic trout ( Salmo obtusirostris ) is a species of fish from the genus Salmo in the salmon family (Salmonidae).
description
The Adriatic trout has been classified as Salmothymus obtusirostris by many authors in its own genus . This classification is considered outdated due to phylogenetic studies.
Compared to the trout ( Salmo trutta ) it has a very short head with a blunt snout. The caudal fin is much more indented. The fish usually does not grow to be more than 50 centimeters 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 teeth weak. In terms of color, this species is similar to the brown trout ( Salmo trutta fario ).
Occurrence
The non-migratory freshwater fish is restricted to rivers in the karst regions in the Dinaric Mountains . As subspecies have been described: Salmo obtusirostris oxyrhynchus Steindachner , 1882 from the Neretva 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 together is only about 500 km², the Adriatic trout is endangered by dam construction, often illegal overfishing and hybridization with imported trout.
