Spirlin
''Alburnoides bipunctatus'', the schneider, spirlin, bleak, riffle minnow or bystranka, is a species of brackish and fresh water ray-finned fish belonging to the family Leuciscidae, which includes the daces, the minnows and related fishes. This is a widespread species in Europe. Taxonomy ''Alburnoides bipunctatus'' was first formally described as ''Cyprinus bipunctatus'' in 1782 by the German naturalist and physician Marcus Elieser Bloch with its type locality given as the Weser River near Minden in Germany. This taxon has been recognised to be a species complex in the 2000s and ''A. bipunctatus'' is now considered to be restricted to Europe. The schneider is classified in the genus ''Alburnoides'' within the subfamily Leuciscinae of the family Leuciscidae. Etymology ''Alburnoides bipunctatus'' belongs to the genus ''Alburnoides'', this name suffixes ''-oides'' on to the genus name ''Alburnus'', which is Latin for whitefish but also refers to the bleak, a name which means pa ...

Marcus Elieser Bloch
Marcus Elieser Bloch (1723–1799) was a German physician and naturalist who is best known for his contribution to ichthyology through his multi-volume catalog of plates illustrating the fishes of the world. Brought up in a Hebrew-speaking Jewish family, he learned German and Latin and studied anatomy before settling in Berlin as a physician. He amassed a large natural history collection, particularly of fish specimens. He is generally considered one of the most important ichthyologists of the 18th century, and wrote many papers on natural history, comparative anatomy, and physiology. Life Bloch was born at Ansbach in 1723 where his father was a Torah writer and his mother owned a small shop. Educated at home in Hebrew literature he became a private tutor in Hamburg for a Jewish surgeon. Here he learned German, Latin and anatomy. He then studied medicine in Berlin and received a doctorate in 1762 from Frankfort on the Oder with a treatise on skin disorders. He then became a ...

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 ...

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 play an important role in schooling behavior, predation, and orientation. Early in the evolution of fish, some of the sensory organs of the lateral line were modified to function as the electroreceptors called ampullae of Lorenzini. The lateral line system is ancient and basal to the vertebrate clade, as it is found in fishes that diverged over 400 million years ago. Function The lateral line system allows the detection of movement, vibration, and pressure gradients in the water surrounding an animal. It plays an essential role in orientation, predation, and fish ... [...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 ...

Alburnoides Maculatus
''Alburnoides maculatus'', the Crimean spirlin or Crimean riffle minnow, is a species of small (7.3 cm max length) freshwater fish in the family Leuciscidae. It is endemic to the Crimea Peninsula. Taxonomy ''Alburnoides maculatus'' was first formally described as ''Alburnus maculatus'' in 1859 by the Baltic German zoologist Karl Fedorovich Kessler with its type locality given as the Salghir River at Simferopol in Crimea, Ukraine. This taxon has been regarded as a synonym of the schneider ('' A. bipunctatus'') but is now accepted as a separate valid species. In 1861 Ludwig Heinrich Jeitteles placed ''Alburnus maculatus'' in the monospecific genus ''Alburnoides'', meaning this taxon is the type species of that genus by monotypy. The genus ''Alburnoides'' is classified in the subfamily Leuciscinae of the family Leuciscidae. Etymology ''Alburnoides maculatus'' belongs to the genus ''Alburnoides'', this name suffixes ''-oides'' on to the genus name ''Alburnus'', which is Lat ...

Alburnus Alburnus
The bleak or common bleak (''Alburnus alburnus'') is a small freshwater coarse fish of the family Leuciscidae, which includes the minnows, daces and bleaks. The common bleak is found in Europe and Western Asia. Description The body of the bleak is elongated and flat. The head is pointed and the relatively small mouth is turned upwards. The anal fin is long and has 18–23 fin rays. The lateral line is complete. The bleak has a shiny silvery colour, and the fins are pointed and colourless. Its maximum length is about 25 cm (10 in). In Europe, the bleak can easily be confused with many other species. In England, young common bream and silver bream can be confused with young bleak, though the pointed, upward-turned mouth of the bleak is already distinctive at young stages. Young roach and ruffe have wider bodies and short anal fins. Occurrence The bleak occurs in Europe and Western Asia: north of the Caucasus, Pyrenees, and Alps, and eastward toward the Volga b ...

Whitefish (fisheries Term)
Whitefish or white fish is a fisheries term for several species of demersal fish with fins, particularly Atlantic cod (''Gadus morhua''), whiting (fish), whiting (''Merluccius bilinearis''), haddock (''Melanogrammus aeglefinus''), Phycidae, hake (''Urophycis''), and pollock (''Pollachius''), among others. Whitefish live on or near the seafloor, and can be contrasted with the Oily fish, oily or pelagic fish, which live away from the seafloor. Whitefish do not have much fish oil, oil in their tissue, and have flakier white or light-coloured flesh. Most of the oil found in their bodies is concentrated in the organs, e.g. cod liver oil. Whitefish can be divided into benthopelagic fish (round fish that live ''near'' the sea bed, such as cod and Coley (fish), coley) and benthic fish (which live ''on'' the sea bed, such as flatfish like plaice). Whitefish is sometimes eaten straight but is often used reconstituted for fishsticks, gefilte fish, lutefisk, surimi (imitation crab meat), e ...

Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest. Latin Root (linguistics), roots appear frequently in the technical vocabulary used by fields such as theology, List of Latin and Greek words commonly used in systematic names, the sciences, List of medical roots, suffixes and prefixes, medicine, and List of Latin legal terms ...
