Leucos Basak
''Leucos basak'', the Albanian roach, Dalmatian roach or Croatian roach, is a species of is a species of freshwater ray-finned fish belonging to the family Leuciscidae, which includes teh daces, Eurasian minnow and related fishes. It is found in the Balkan Peninsula where its natural habitats are intermittent rivers and freshwater lakes. Taxonomy ''Leucos basak'' was first formally described in 1843 by the Austrian ichthyologist Johann Jakob Heckel with its type locality given as Croatia. It is a species in the genus ''Leucos'' within the subfamily Leuciscinae of the family Leuciscidae. Etymology ''Leucos basak'' belongs to the genus ''Leucos'', this name is derived from the Greek ''leukos'' which means "white", the genus was named by Johann Jakob Heckel and he did not explain why he chose this name, it may be that it refers to the silvery colour of '' Squalius aula''.

Johann Jakob Heckel
Johann Jakob Heckel (23 January 1790 – 1 March 1857) was an Austrian taxidermist, zoology, zoologist, and ichthyology, ichthyologist from Mannheim in the Electoral Palatinate. He worked at the Royal natural history cabinet in Vienna which later became the Austrian Museum of Natural History. Life Heckel was born in Mannheim, the son of a namesake music teacher and Sophia née Reinhardt. He also had a namesake brother who studied music and was educated at home and lived in Vienna for a while. Another brother was Karl Ferdinand Heckel (1800-1870) who also studied music. In 1805 the family fled the French to Pressburg and then to Pest. Heckel visited the Georgicon agricultural college in 1806. His father bought a farm in Gumpoldskirchen and after the death of his father in December 1811, his mother took over the farm, assisted by his brother. He married Barbara Baumgartner in 1817 and in 1818 he was working at the Vienna Naturaliencabinet (which later became the Naturhistorisches Mu ...

Leuciscinae
Leuciscinae is a subfamily of freshwater Actinopterygii, ray-finned fishes belonging to the Family (biology), family Leuciscidae, which includes the fishes known as daces, chubs, shiners and minnows. The fishes in this subfamily are mainly found in Eurasia, with one genus (''Golden shiner, Notemigonus'') in North America. Genera Leuciscinae contains the following genera: * ''Abramis'' Georges Cuvier, Cuvier, 1816 (Common bream) * ''Acanthobrama'' Johann Jakob Heckel, Heckel 1843 (Bleaks) * ''Achondrostoma'' Joana Isabel Robalo, Robalo, Vitor C.

Lake Skadar
Lake Skadar or Lake Scutari (, ; cnr-Cyrl-Latn, Скадарско језеро, Skadarsko jezero, )also called Lake Shkodra (and ''Lake Shkodër'')lies on the border of Albania and Montenegro, and is the largest lake in Southern Europe. It is named after the Albanian city of Shkodër which lies at its southeastern coast. It is a karst lake. The Montenegrin section of the lake and surrounding land have been designated as a national park, while the Albanian part constitutes a nature reserve and a Ramsar site. Geography Lake Skadar is the largest lake in the Balkan Peninsula with a surface area that seasonally fluctuates between and . Lake Skadar itself is located in the western Balkan region. The lake is located in the border area between Montenegro and Albania, the Montenegrin share of the area of the lake is larger than the Albanian one. The lake's water level also varies seasonally from above sea level. The lake extends northwest to southeast, and it is approximately l ...

Bojana River
The Buna () river, also known as Bojana ( cnr-Cyrl, Бојана), is a river in Albania and Montenegro which flows into the Adriatic Sea. An outflow of Lake Skadar measured from the source of the lake's longest tributary, the Morača, the Morača-Shkodra Lake-Bojana system is long. Name The modern Albanian name of the river is derived from Illyrian ''Barbanna'' and follows Albanian phonetic sound rules. History The river appears as the ''Fiume Boiana'' in a 1688 map of the region, published by Vincenzo Coronelli. At the time, the river did not have any tributaries feeding into it. The presence of the Drin river having its own mouth into the Adriatic Sea on the map suggests that the Drin did not join the Buna river until after 1688. Over time, the frequent changes in its course and water levels led to flooding of its banks and the surrounding plains. Such occurrences led to the slow decay of the Monastery of Saints Sergius and Bacchus, located right on the bank of the B ...

Neretva River
The Neretva (, sr-Cyrl, Неретва), 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 (higher than 15 metres) provide flood protection, electricity and water storage. The Neretva is recognized for its natural environment and diverse landscapes. Freshwater ecosystems have suffered from an increasing population and the associated development pressures. One of the most valuable natural resources of Bosnia and Herzegovina and Croatia is its freshwater resource, contained by an abundant wellspring and clear rivers. Situated between the major regional rivers (Drina river on the east, Una river on the west and the Sava river) the Neretva basin contains the most significant source of drinking water. The Neretva is notable among rivers of the Dinaric Alps region, especially regarding its diverse ecosystems and habitats, flora and fauna, cultural and historic heritage. Its name has bee ...

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ...

Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Croatian Language
Croatian (; ) is the standard language, standardised Variety (linguistics)#Standard varieties, variety of the Serbo-Croatian pluricentric language mainly used by Croats. It is the national official language and literary standard of Croatia, one of the official languages of Bosnia and Herzegovina, Montenegro, the Serbian province of Vojvodina, the European Union and a recognized minority language elsewhere in Serbia and other neighbouring countries. In the mid-18th century, the first attempts to provide a Croatian literary standard began on the basis of the Neo-Shtokavian dialect that served as a supraregional lingua franca – pushing back regional Chakavian, Kajkavian, and Shtokavian vernaculars. The decisive role was played by Croatian Vukovians, who cemented the usage of Ijekavian Neo-Shtokavian as the literary standard in the late 19th and the beginning of the 20th century, in addition to designing a phonological orthography. Croatian is written in Gaj's Latin alphabet. B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...
