The brown trout is a species of salmonid ray-finned fish and the most widely distributed species of the genus Salmo, endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced globally as a game fish, even becoming one of the world's worst invasive species outside of its native range.
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.
The Lake Prespa is located on the tripoint of North Macedonia, Albania and Greece. It is a system of two lakes separated by an isthmus: the Great Prespa Lake, divided between the three countries, and the Little Prespa Lake, mostly within Greece. They are the highest tectonic lakes in the Balkans, at an elevation of 853 metres (2,799 ft).
Baba, also known by the name of its highest peak, Pelister, is a mountain in North Macedonia. The Pelister peak overlooks the city of Bitola. Baba is the third highest mountain in North Macedonia. Other peaks besides Pelister are Dva Groba, Veternica, Musa, Ržana, Široka, Kozji Kamen, Griva and Golema Čuka in North Macedonia, and Belavoda, Kirko. The Baba massif splits up the rivers in the region, so that they either flow towards the Adriatic Sea.
Ohrid trout or the Lake Ohrid brown trout is an endemic species of trout in Lake Ohrid and in its tributaries and outlet, the Black Drin river, in North Macedonia and Albania. Locally, the fish is known as охридска пастрмка in Macedonian and Koran or Korani in Albanian.
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.
The Mexican golden trout is a species of fish in the family Salmonidae. The species is endemic to high-elevation headwaters of the Fuerte River, Sinaloa River, and Culiacán River drainages in the Sierra Madre Occidental in Mexico.
Salmo aphelios is a species of trout, a salmonid fish endemic to Lake Ohrid in North Macedonia and Albania in the Balkans.
Salmo balcanicus is a type of trout, a fish in the family Salmonidae. It is endemic to Lake Ohrid and its outlet in North Macedonia and Albania in the Balkans.
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.
Salmo platycephalus, known as the flathead trout, Ala balik or the Turkish trout, is a type of trout, a fish in the family Salmonidae. It is endemic to southeastern Turkey. It is known only from one population, which occupies three streams, tributaries of the Zamantı River in the Seyhan River basin. The population itself is abundant, but subject to threat by habitat loss, since the range is small. Also, predation of juveniles by introduced rainbow trout may cause population decline. The species is classified as critically endangered.
Mexican native trout —Mexican rainbow trout, sometimes Baja rainbow trout and Mexican golden trout —occur in the Pacific Ocean tributaries of the Baja California peninsula and in the Sierra Madre Occidental of northwestern Mexico as far south as Victoria de Durango in the state of Durango. Many forms of the Mexican rainbow trout, subspecies of the rainbow trout, have been described. The Mexican golden trout is a recognized species.
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.
Prespa National Park is a national park situated in southeastern Albania on the border triangle shared with Greece and North Macedonia. At approximately 277.5 km2 (107.1 sq mi), the park encompasses the country's sections of the Great and Small Prespa Lake. It is considerably characterised by high mountains, narrow islands, vast freshwater wetlands, salt marshes, meadows, reed beds and dense forests.
Over 22,500 species of wildlife have been recorded in North Macedonia. Over 10,000 of these are insects, which include 3,000 beetle species and large numbers of Lepidoptera, flies, and Hymenoptera. Aside from insects, other large arthropod groups include Chelicerata and crustaceans. Among vertebrates, more than 300 species of birds recorded, although not all nest in the country. There are over 80 species of both fish and mammals, 32 reptiles, and 14 amphibians.
Salmo farioides, commonly known as the West Balkan trout, the Adriatic brown trout, or the Balkan brook trout, is a species of ray-finned fish found in the Balkans, including Albania, Croatia, North Macedonia, among others. It is an important fish in numerous rivers and lakes throughout the region. Identification of Salmo farioides is difficult due to the high degree of endemism in the western Adriatic and Mediterranean area, particularly among salmonid species, and because of high phenotypic diversity among trout populations specifically.
