Abrau Sprat
Abrau sprat, ''Clupeonella abrau'', is a species of freshwater fish in the family Clupeidae. It is found landlocked in Russia in a single locality, Lake Abrau, located at 70 m above sea level near the Black Sea coast close to Novorossiysk. The lake is small and has been stocked by several alien species, whence the Abrau sprat is considered critically endangered. A sprat of the Lake Apolyont in Turkey, linked to the Sea of Marmara, was earlier treated as a subspecies of the Abrau sprat, ''Clupeonella abrau muhilisi'', but has more recently been considered an independent species ''Clupeonella muhlisi ''Clupeonella muhlisi'' is a species of clupeid fish endemic to Lake Uluabat in Turkey, linked to the Sea of Marmara.

Freshwater Fish
Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of salinity. To survive fresh water, the fish need a range of physiology, physiological adaptations. 41.24% of all known species of fish are found in fresh water. This is primarily due to the rapid speciation that the scattered habitats make possible. When dealing with ponds and lakes, one might use the same basic models of speciation as when studying island biogeography. Physiology Freshwater fish differ physiologically from salt water fish in several respects. Their gills must be able to diffuse dissolved gases while keeping the salts in the body fluids inside. Their scales reduce water diffusion through the skin: freshwater fish that have lost too many scales will die. They also have well developed kidneys to reclaim salts from body flui ...

Lake Apolyont
Lake Uluabat ( tr, Uluabat Gölü and ) is the name of a freshwater lake in the vicinity of Bursa, Turkey. It is a large lake, covering an area of between 135 and 160 km2 depending on the water level, but very shallow, being only 3 m deep at its deepest point. The lake contains eight islands and one other that is sometimes an island and sometimes a peninsula. The largest island is known as Halilbey Island. In the southwest the lake is fed by the Mustafakemalpaşa River, which has formed a silty delta. Water leaves the lake by way of the Ulubat stream, flowing to the west, and reaches the Sea of Marmara via the Susurluk River. Most shores of the lake are covered in submerged plants, and it has the most extensive white water lily beds in Turkey. Uluabat Lake is one of the breeding areas for the endangered pygmy cormorant (''Phalacrocorax pygmeus''). The latest DHKD (Society for the Protection of Nature Turkey) survey in June 1998 found 823 pygmy cormorant pairs, 105 night h ...

Fish Of Russia
Fish are aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, 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 vertebrate, 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 placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clupeonella Muhlisi
''Clupeonella muhlisi'' is a species of clupeid fish endemic to Lake Uluabat in Turkey, linked to the Sea of Marmara. It is a small fish, up to 8 cm in length, that shoals at the water surface. It feeds on pelagic crustaceans and fish eggs. This population of sprat has previously been considered either conspecific with ''Clupeonella abrau'' that inhabits Lake Abrau, Russia, near the northeastern Black Sea coast, or a distinct subspecies of that species, ''Clupeonella abrau muhlisi'', or a population belonging to the more widespread Black Sea sprat (''Clupeonella cultriventris The Black Sea sprat, ''Clupeonella cultriventris'', is a small fish of the herring family, Clupeidae.

Sea Of Marmara
The Sea of Marmara,; grc, Προποντίς, Προποντίδα, Propontís, Propontída also known as the Marmara Sea, is an inland sea located entirely within the borders of Turkey. It connects the Black Sea to the Aegean Sea via the Bosporus and Dardanelles straits, separating the country's European and Asian sides. The Sea of Marmara is a small sea with an area of , and dimensions of . Its greatest depth is . Name The Sea of Marmara is named after the largest island to its south side which is called Marmara Island because it is rich in marble (Greek (''mármaron'') "marble)." In classical antiquity it was known as the Propontis, which is derived from the Greek words ''pro-'' (before) and ''pontos'' (sea) and reflects the fact that the Ancient Greeks used to sail through it to reach the Black Sea that they called Pontos. Mythology In Greek mythology, a storm on the Propontis brought the Argonauts back to an island they had left, precipitating a battle in which ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clupeidae
Clupeidae is a family of ray-finned fishes, comprising, for instance, the herrings, shads, sardines, hilsa, and menhadens. The clupeoids include many of the most important food fishes in the world, and are also commonly caught for production of fish oil and fish meal. Many members of the family have a body protected with shiny cycloid (very smooth and uniform) scales, a single dorsal fin, and a fusiform body for quick, evasive swimming and pursuit of prey composed of small planktonic animals. Due to their small size and position in the lower trophic level of many marine food webs, the levels of methylmercury they bioaccumulate are very low, reducing the risk of mercury poisoning when consumed. Description and biology Clupeids are mostly marine forage fish, although a few species are found in fresh water. No species has scales on the head, and some are entirely scaleless. The lateral line is short or absent, and the teeth are unusually small where they are present at all. Clupe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
