Salmo balcanicus (S. L. Karaman, 1927) | |
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 balcanicus is one of four different forms of the Ohrid trout complex which is endemic to the single lake, along with Salmo letnica , Salmo aphelios and Salmo lumi . The various forms, suggested to be different species, are distinguished by their breeding time and habitat, by which they in practice are reproductively isolated from each other. There is no support for their distinct species status from molecular data however. [2] Salmo balcanicus specifically spawns from October to January at the outlet of the lake, Black Drin, in the northwestern end of the lake near the Macedonian-Albanian border area. As the river has been dammed, it is suspected that the population may have gone extinct.
The flesh of Salmo balcanicus is typically of pale pink colour. Overall the Ohrid trouts are silvery in colour, with black dots. Red dots occur along the lateral line. Salmo balcanicus can grow to 40 cm (16 in) length.
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.
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).
The gillaroo is a species of trout which eats primarily snails and is only proven to inhabit Lough Melvin in Ireland.
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. The scientific name has changed several times through history; synonyms include Thymallus microlepis, Salmothymus obtusirostris and Salar obtusirostris.
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.
Salmo aphelios is a species of trout, a salmonid fish endemic to Lake Ohrid 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 peristericus, or the Prespa trout is a variety of trout, a freshwater fish in the family Salmonidae. It is endemic to the Lake Prespa watershed at the border area of Greece and North Macedonia.
The Ohrid spirlin is a fish species of family Cyprinidae. This species is endemic to Lake Ohrid in North Macedonia and Albania in the Balkans. It is a benthopelagic temperate freshwater fish, up to 9 cm in length. It was originally named as a subspecies of Alburnoides bipunctatus. It is threatened by non-indigenous species of fish, many of which have been introduced into Lake Ohrid.
The fish fauna of the Neretva river basin in the western Balkans is representative of the Dinaric karst region and characterized by several endemic and endangered 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.
