Salmo Marmoratus
Salmo marmoratus, the marble trout, is a species of freshwater fish in the family Salmonidae.
Salmo Marmoratus lives only in the watercourses of the Adriatic basin, in the rivers of northern Italy, Slovenia, Bosnia and Herzegovina, Montenegro, Macedonia and Albania.
It is most numerous in northern Italian rivers and in the Soča river in Slovenia. With regard to the construction of hydroelectric power plants and reservoirs on the Neretva, its survival there is questionable.
It is especially threatened by the uncontrolled introduction of breeding forms of brown trout, with which it interbreeds, and their offspring can reproduce.
It is characterized by a distinctive marbled color pattern and high growth capacity.Its typical size is 30–70 cm. The largest caught was 120 cm and 22.5 kg.
Endangered species in Croatia, the main reason for the decrease in numbers is due to construction of hydroelectric power plants.
