Salmo ohridanus, also known by the local name as the belvica in North Macedonia or belushka in Albania, is a species of freshwater salmonid fish, endemic to Lake Ohrid in Albania and North Macedonia. [2] [1] [3]
Salmo ohridanus is a relatively small fish, usually shorter than 30 cm and less than 0.5 kg weight. [2] It is a commercially exploited species subject to heavy fishing, and has been bred in fish farms for over 50 years. It has also been intentionally hybridized with another endemic species, the Ohrid trout ( Salmo letnica ). It is threatened by the hybridization, degradation of water quality and overfishing; but the stock remains abundant. [1]
In earlier literature the belvica has variously been treated as belonging to suggested endemic genera Acantholingua and Salmothymus . [4] [3] Genetic studies however indicate it is a good member of the genus Salmo , and closest to the softmouth trout Salmo obtusirostris. [5] Nevertheless, it is quite distinct from the brown trout complex. [3]
North Macedonia is a country situated in southeastern Europe with geographic coordinates 41°50′N22°00′E, bordering Kosovo and Serbia to the north, Bulgaria to the east, Greece to the south and Albania to the west. The country is part of the wider region of Macedonia and makes up most of Vardar Macedonia. The country is a major transportation corridor from Western and Central Europe to Southern Europe and the Aegean Sea. North Macedonia is a landlocked country but has three major natural lakes: Lake Ohrid, Lake Prespa and Lake Dojran. It has a water area of 857 km2, while its land area is 24,856 km2.
The Neretva, also known as Narenta, is one of the largest rivers of the eastern part of the Adriatic basin. Four hydroelectric power plants with large dams provide flood protection, electricity and water storage. The Neretva is recognized for its natural environment and diverse landscapes.
Salmo is a genus of ray-finned fish from the subfamily Salmoninae of family Salmonidae, and is part of the tribe Salmonini along with the sister genera Salvelinus and Salvethymus. Almost all Salmo species are native only in the Old World, the only exception being the Atlantic salmon, which is also naturally found across the North Atlantic in eastern North America.
Lake Ohrid is a lake which straddles the mountainous border between the southwestern part of North Macedonia and eastern Albania. It is one of Europe's deepest and oldest lakes, with a unique aquatic ecosystem of worldwide importance, with more than 200 endemic species.
Salmo obtusirostris salonitana is an endemic trout subspecies found in the Jadro River in the vicinity of Solin, and in the nearby Žrnovnica River, where it was introduced in 1964. The upper reaches of the Jadro River including Jadro Spring, covering an area of 7.8 hectares, have been protected as an ichthyological reserve since 1984, for the purpose of preserving this endangered fish species, S. o. salonitana.
Salmo obtusirostris, commonly known as the softmouth trout, also known as the Adriatic trout, or Adriatic salmon, is a species of salmonid fish endemic to a handful rivers spilling into Adriatic in the Western Balkans, in southeastern Europe, namely in Bosnia and Herzegovina, Croatia and Montenegro.

Salmo carpio, also known as the carpione, is a salmonid fish endemic to Lake Garda in Italy. It has been introduced to a number of other lakes in Italy and elsewhere but unsuccessfully in all cases. The population in Lake Garda has been strongly declining, and is considered critically endangered. The main threats are due to overfishing, pollution and possibly competition from introduced species such as Coregonus and other Salmonidae.

Salmo dentex is a variety of trout, a freshwater fish in the family Salmonidae, found in the western Balkans. Until recently the identity, biological distinctness and species status of the dentex trout were not properly clarified, but genetic data now suggest it is not a monophyletic unit that could be distinguished from other salmonids as a separate species.
Salmo lumi is a type of trout, a fish in the family Salmonidae. It is endemic to Lake Ohrid and its tributaries in Albania and North Macedonia.
Salmo marmoratus, the marble trout, is a species of freshwater fish in the family Salmonidae. It is characterized by a distinctive marbled color pattern and high growth capacity. The marble trout is found in only a handful of drainages and rivers of the Adriatic basin in Italy, Slovenia, Croatia, Bosnia and Herzegovina, and Montenegro, while in Albania, the species is considered most likely extirpated.

Ohrid-Prespa Transboundary Biosphere Reserve is a biosphere reserve encompassing the area of Lake Ohrid and Lake Prespa, on North Macedonia and Albania.
For a small country, Albania is characterised by a considerable wealth of terrestrial and marine ecosystems and habitats with contrasting floral, faunal, and fungal species, defined in an area of 28,748 square kilometres. Most of the country is predominantly of Mediterranean character, comprehending the country's center and south, while the alpine affinity is more visible in the northeast.
