Misgurnus Fossilis
The weatherfish (''Misgurnus fossilis'') is a species of true loach that has a wide range in Europe and some parts of Asia. It is an omnivorous scavenger bottom feeder, using its sensitive barbels to find edible items. The diet mostly consists of small aquatic invertebrates along with some detritus. The weatherfish is long and thin which allows it to burrow through the substrate and navigate through places that deeper bodied fish would have trouble with. It grows up to 30 cm (12 in) in total length, though there are fishermen who say they have caught longer, up to 45 cm (17.7 in). If true, this would make ''Misgurnus fossilis'' the largest species of true loach. This loach has a very wide range, especially in Europe. It occurs north of the Alps, from the Meuse River in western Europe all the way to the Neva River in northwestern Russia. It also occurs in the northern part of the Black Sea basin from the Danube River to the Kuban River, and in the Caspian Sea ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danube
The Danube ( ; ) is a river that was once a long-standing frontier of the Roman Empire and today connects 10 European countries, running through their territories or being a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The largest cities on the river are Vienna, Budapest, Belgrade and Bratislava, all of which are the capitals of their respective countries; the Danube passes through four capital cities, more than any other river in the world. Five more capital cities lie in the Danube's basin: Bucharest, Sofia, Zagreb, Ljubljana and Sarajevo. The fourth-largest city in its basin is Munich, the capital of Bavaria, standing on the Isar River. The Danube is the second-longest river in Europe, after the Volga in Russia. It flows through much of Central and Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1758
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 ...

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. Fresh water i ...

Misgurnus
Misgurnus is a genus of true loaches found in Europe and Asia. The origin of the name ''Misgurnus'' comes from the Greek word (to hate) and the Turkish (loud), a name given to them due to their habit of becoming very active during barometric pressure changes that occur during thunderstorms. The common names, weather loach or weatherfish, also derive from this behavior. Some species of misgurnus are eaten, mostly in Asia, and are also sold as pets in the aquarium trade. Their average size can range for 6 to over 12 inches. Species There are currently seven recognized species in this genus:Kottelat, M.

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.

Pond Loach
The pond loach (''Misgurnus anguillicaudatus''), also known as the Dojo loach or oriental weatherfish, is a freshwater fish in the loach family Cobitidae. They are native to East Asia but are also popular as an aquarium fish and introduced elsewhere in Asia and to Europe, America and Australia. The alternate name weather loach is shared with several other Cobitidae, including the other members of the genus ''Misgurnus'' and the spotted weather loach (''Cobitis taenia'', commonly known as spined loach). This term comes from their ability to detect changes in barometric pressure and react with frantic swimming or standing on end. This is because before a storm the barometric pressure changes, and this is known to make these fish more active. The pond loach also comes in a variety of colors, such as pink, orange, albino and gray. Description Like many other loaches, pond loaches are slender and eel/snake-like. They can vary in colour from yellow to olive green, to a common light br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ralja (river)
The Ralja ( sr-Cyrl, Раља) is a river in the Šumadija region of Serbia. It is a 51 km long left tributary to the Jezava, a distributary of the Great Morava river. It also gives its name to the surrounding Šumadija's subregion of Ralja. Course The Ralja originates from the northern part of the Kosmaj mountain, north of the village of Velika Ivanča, in the Sopot municipality of the City of Belgrade. Almost from the source, the river valley is a route for the Belgrade-Niš railway. At the villages of Popović and Mali Požarevac, the Ralja turns straight to the east for the rest of its flow and also from this point, the Belgrade-Niš highway joins the railroad. As it flows next to the Belgrade suburbs of Dražanj, Umčari and Živkovac, the Ralja divides the Podunavlje region from the Ralja region of the low Šumadija, and leaves the City of Belgrade area at the village of Malo Orašje. After the villages of Binovac, Kolari, Vrbovac and Ralja, the river separates from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
