Salmo Balcanicus
''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.Lake Ohrid trouts Balkan trout restoration group. Downloaded on 19 May 2010.

Stanko Karaman
Stanko Luka Karaman (8 December 1889 – 17 May 1959) was a Yugoslav biologist of Bosnian Serb ancestry, researcher on amphipod and isopod crustaceans. In 1926 he founded the Museum of South Serbia (later - Macedonian Museum of Natural History) in Skopje and in 1928, the Zoological Garden of Skopje. Several species are named after him, for example '' Delamarella karamani'' Petkovski, 1957 (Harpacticoida), '' Stygophalangium karamani'' Oudemans, 1933 (Arachnida), or '' Macedonethes stankoi'' I. Karaman, 2003 (Isopoda Isopoda is an order of crustaceans that includes woodlice and their relatives. Isopods live in the sea, in fresh water, or on land. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, an ...). Other taxa named ''karamani'' are labeled after his son Gordan S.

Salmo Aphelios
''Salmo aphelios'' is a species of trout, a salmonid fish endemic to Lake Ohrid in North Macedonia and Albania in the Balkans. ''Salmo aphelios'' is one of four different forms of the Ohrid trout complex within the single lake, along with '' S. balcanicus'', '' S. letnica'', and '' S. lumi''. The various trout forms, which have been suggested to be different species, are distinguished by their breeding time and habitat, by which they in practice are thought to be reproductively isolated from each other. Genetic data have not supported their distinction, though. ''Salmo aphelios'' specifically spawns from May to July near the underwater springs on the eastern shore of the lake, at the Macedonian-Albanian border area. Its flesh is typically of orange colour. Overall, the Ohrid trouts are silvery in colour, with black dots. Red dots occur along the lateral line The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect ...

Fish Described In 1927
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Freshwater Fish Of Europe
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Salmo
''Salmo'' is a genus of ray-finned fish from the family Salmonidae. The single ''Salmo'' species naturally found in the Atlantic North America is the Atlantic salmon, whereas the salmon and trout of the Pacific basin belong to another genus, ''Oncorhynchus''. The natural distribution of ''Salmo'' also extends to North Africa and to West Asia around the Black Sea basin. The generic name ''Salmo'' derives from the Latin ''salmō'' (salmon). The number of distinct species and subspecies in ''Salmo'' is a debated issue. Atlantic salmon and brown trout are widespread species, while most of the other taxa are narrowly distributed forms endemic to single watersheds. Species The species currently listed in this genus are: * '' Salmo abanticus'' Tortonese, 1954 (Lake Abant trout) * '' Salmo aestivalis'' Fortunatov, 1926 (Lake Sevan summer trout) * '' Salmo akairos'' Delling & Doadrio, 2005 (Lake Ifni trout) * '' Salmo aphelios'' Kottelat, 1997 (summer trout) * '' Salmo balcanicus'' ...

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked. Most amphibian larvae and some fully aquatic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Drin
The Black Drin, or Black Drim ( sq, Drini i Zi, mk, , translit=Crn Drim) is a river in North Macedonia and Albania. It flows out of Lake Ohrid in Struga, North Macedonia. It is long and its drainage basin is . Its average discharge is . After about it crosses the border to Albania, west of Debar, North Macedonia. It merges with the White Drin in Kukës to form the Drin, which flows into the Adriatic Sea. It drains most of the eastern border region of Albania. The name is ancient - Drinius, Trinius (Pliny), Δρεῖνος (Ptolemy). Its origin is Illyrian from older ''*Drūn'', from Indo-European ''*drū''- into Old Indian ''drāvayate'', run, flow, Avestan ''dru'', run.Георгиев, Вл., Ив. Гълъбов, Й. Заимов, Ст.

Salmo Lumi
''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 lumi'' is one of four different forms of the Ohrid trout complex within Lake Ohrid, along with ''Salmo letnica'', ''Salmo balcanicus'' and ''Salmo aphelios''. There are however no known morphological characters that would clearly distinguish it from the others. The head and body of these trout are silver in colour, with black dots. Red dots occur along the lateral line The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water.

Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', '' Salmo'' and '' Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Balkans
The Balkans ( ), also known as the Balkan Peninsula, is a geographical area in southeastern Europe with various geographical and historical definitions. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish Straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Mount Musala, , in the Rila mountain range, Bulgaria. The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. The term ''Balkan Peninsula'' was a synonym for Rumelia in the 19th century, the European provinces of the Ottoman Empire. It had a ...
