Rhodeus Pseudosericeus
''Rhodeus pseudosericeus'' is a temperate freshwater fish belonging to the Acheilognathinae subfamily of the family Cyprinidae. It originated in the Namhan River system in the Gyeonggi-do and Gangwon-do provinces of Korea. It was originally described as ''Acanthorhodeus atremius'' by Jordan & Thompson in 1914. The fish reaches a length up to 6.1 cm (2.4 in). When spawning, the females deposit their eggs inside bivalve Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts.

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Freshwater
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 ...

Fish
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 arthrop ...

Acheilognathinae
The bitterling-like cyprinids form the cyprinid subfamily Acheilognathinae. This subfamily contains four genera, although the Khanka spiny bitterling is often placed in '' Acheilognathus'', and at least 71 described species to date. Over half of the species are in the genus ''Acheilognathus''. Genera contained herein are: *'' Acanthorhodeus'' – Khanka spiny bitterling *'' Acheilognathus'' (42 species) *'' Paratanakia'' (monotypic) *'' Pseudorhodeus'' (monotypic) *''Rhodeus ''Rhodeus'' is a genus of cyprinid fish, consisting of 23 species called bitterlings.

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used ...

Namhan River
Namhan River (Namhan-gang, South Han River) is a major river of South Korea, the 2nd-longest. It is a tributary of the Han River. It is famous for clean and clear water, especially in its upper reaches and tributaries, and serves as a source of water for Seoul. A popular bike path follows the river. Several sections of it are used for public recreation, including rafting; some of these sections have their own traditional names, such as the "Dong-gang" or Dong River stretch, popular for natural beauty. Some part of this river was found to be contaminated by bis-(2-ethylhexyl)-phthalate (DEHP) with 50 ppb.

Gyeonggi-do
Gyeonggi-do (, ) is the most populous province in South Korea. Its name, ''Gyeonggi'', means "京 (the capital) and 畿 (the surrounding area)". Thus, ''Gyeonggi-do'' can be translated as "Seoul and the surrounding areas of Seoul". Seoul, the nation's largest city and capital, is in the heart of the area but has been separately administered as a provincial-level ''special city'' since 1946. Incheon, the nation's third-largest city, is on the coast of the province and has been similarly administered as a provincial-level ''metropolitan city'' since 1981. The three jurisdictions are collectively referred to as ''Sudogwon'' and cover , with a combined population of 25.5 million—amounting to over half of the entire population of South Korea. History Gyeonggi-do has been a politically important area since 18 BCE, when Korea was divided into three nations during the Three Kingdoms period. Ever since King Onjo, the founder of Baekje (one of the three kingdoms), founded the govern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gangwon-do (South Korea)
Gangwon Province is a province of South Korea, with its capital at Chuncheon. It is bound on the east by the Sea of Japan, and borders Gyeonggi Province to its west, North Gyeongsang Province and North Chungcheong Province to its south, and the Military Demarcation Line to the north, separating it from North Korea's Kangwŏn Province. Before the division of Korea in 1945 Gangwon and Kangwŏn Provinces formed a single province. Pyeongchang County in Gangwon hosted the 2018 Winter Olympics and 2018 Winter Paralympics, with Gangwon hosting the 2024 Winter Youth Olympics. History Gangwon-do was one of the Eight Provinces of Korea during the Joseon Dynasty, formed in 1395, deriving its name from the names of the principal cities of Gangneung () and the provincial capital Wonju (). In 1895 Gangwon-do was replaced by the Districts of Chuncheon (''Chuncheon-bu;'' ) in the west and Gangneung (''Gangneung-bu;'' ) in the east, with Wonju becoming a part of Chungju Distric ...

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the " Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
