Ou River (Zhejiang)
The Ou River () or Oujiang is the second-largest river in the Zhejiang province of eastern China. The river flows before finally reaching the city of Wenzhou and emptying into the East China Sea, into which it discharges of water annually. Shen Jiang (), Jiang Yongjia (), and Wenjiang () are all former names for this river. Fauna The Ou River has a rich fish fauna. A 2010 survey recorded 60 different fish species, with goldfish, bagrid catfish, and ''Pseudobagrus tenuis'' being the most prolific in range. Compared to a 1972 survey, 20 new species were recorded, including two alien species (Mozambique tilapia and largemouth bass); however, 34 species recorded in 1972 were absent in 2010, and overall fish density was lower.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Zhejiang
Zhejiang ( or , ; , also romanized as Chekiang) is an eastern, coastal province of the People's Republic of China. Its capital and largest city is Hangzhou, and other notable cities include Ningbo and Wenzhou. Zhejiang is bordered by Jiangsu and Shanghai to the north, Anhui to the northwest, Jiangxi to the west and Fujian to the south. To the east is the East China Sea, beyond which lies the Ryukyu Islands. The population of Zhejiang stands at 64.6 million, the 8th highest among China. It has been called 'the backbone of China' due to being a major driving force in the Chinese economy and being the birthplace of several notable persons, including the Chinese Nationalist leader Chiang Kai-shek and entrepreneur Jack Ma. Zhejiang consists of 90 counties (incl. county-level cities and districts). The area of Zhejiang was controlled by the Kingdom of Yue during the Spring and Autumn period. The Qin Empire later annexed it in 222 BC. Under the late Ming dynasty and the Qing ...

East China Sea
The East China Sea is an arm of the Western Pacific Ocean, located directly offshore from East China. It covers an area of roughly . The sea’s northern extension between mainland China and the Korean Peninsula is the Yellow Sea, separated by an imaginary line between the eastern tip of Qidong at the Yangtze River estuary and the southwestern tip of South Korea's Jeju Island. The East China Sea is bounded in the east and southeast by the middle portion of the first island chain off the eastern Eurasian continental mainland, including the Japanese island of Kyushu and the Ryukyu Islands, and in the south by the island of Taiwan. It connects with the Sea of Japan in the northeast through the Korea Strait, the South China Sea in the southwest via the Taiwan Strait, and the Philippine Sea in the southeast via gaps between the various Ryukyu Islands (e.g. Tokara Strait and Miyako Strait). Most of the East China Sea is shallow, with almost three-fourths of it being less than ...

Goldfish
The goldfish (''Carassius auratus'') is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. Goldfish released into the wild have become an invasive pest in parts of North America. Native to East Asia, the goldfish is a relatively small member of the carp family (which also includes the Prussian carp and the crucian carp). It was first selectively bred for color in imperial China more than 1,000 years ago, and several distinct breeds have since been developed. Goldfish breeds vary greatly in size, body shape, fin configuration, and coloration (various combinations of white, yellow, orange, red, brown, and black are known). History Various species of carp (collectively known as Asian carp) have been bred and reared as food fish for thousands of years in East Asia. Some of these normally gray or silver species have a tendency to produce red, orange or yellow ...

Bagrid Catfish
The Bagridae are a family of catfish that are native to Africa ('' Bagrus'') and Asia (all other genera) from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes. Many large bagrids are important as a source of food. Some species are also kept as aquarium fishes. Physical characteristics The dorsal fin is preceded by a spine. The adipose fin is present and can have a relatively long base in some species. The pectoral fin spine can be serrated. The body is completely naked (they have no scales). The maximum length is about . Fishes of the family Bagridae have four pairs of well-developed barbels covered by a layer of taste bud-enriched epithelium. Taxonomy The taxonomy of this family has changed rapidly. Nelson (2006) comments how "the family is very different from that recognized in Nelson (1994)". Claroteidae and Austroglanididae contain species that were previously bagrids. Auchenoglanididae is considered by some ...

Pseudobagrus Tenuis
''Pseudobagrus'' is a genus of bagrid catfishes that inhabit streams and rivers throughout East Asia. About half of these species occur in China. The two ''Coreobagrus'' species, ''C. brevicorpus'' and ''C. ichikiwai'', are both treated in some recent literature as valid in ''Pseudobagrus''. It has been noted that ''Pelteobagrus'' may not be monophyletic if species placed in ''Pseudobagrus'' and ''Coreobagrus'' were excluded. The taxonomy of this genus is unclear and many authorities treat it as a junior synonym of ''Tachysurus''. ''Pseudobagrus'' species are small- to mid-sized bagrid catfishes. These fish all have an inferior mouth; narial openings widely separated; four pairs of barbels; top of head covered by skin in most species; two dorsal fin spines; pelvic fin small; and caudal fin emarginate, truncate or round. One fossil species, '' P. ikiensis'' Watanabe & Uyeno, is known from the Middle Miocene of Japan.Watanabe, K. and Uyeno, T.; ''Fossil bagrid catfishes from Japa ...

Alien Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyta ...

Mozambique Tilapia
The Mozambique tilapia (''Oreochromis mossambicus'') is an oreochromine cichlid fish native to southeastern Africa. Dull colored, the Mozambique tilapia often lives up to a decade in its native habitats. It is a popular fish for aquaculture. Due to human introductions, it is now found in many tropical and subtropical habitats around the globe, where it can become an invasive species because of its robust nature. These same features make it a good species for aquaculture because it readily adapts to new situations. It is known as black tilapia in Colombia and as blue kurper in South Africa. Description The native Mozambique tilapia is laterally compressed, and has a deep body with long dorsal fins, the front part of which have spines. Native coloration is a dull greenish or yellowish, and weak banding may be seen. Adults reach up to in standard length and up to . Size and coloration may vary in captive and naturalized populations due to environmental and breeding pressures. It ...

Largemouth Bass
The largemouth bass (''Micropterus salmoides'') is a carnivorous freshwater gamefish in the Centrarchidae ( sunfish) family, a species of black bass native to the eastern and central United States, southeastern Canada and northern Mexico, but widely introduced elsewhere. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, bucketmouth, largies, Potter's fish, Florida bass, Florida largemouth, green bass, bucketmouth bass, Green trout, gilsdorf bass, Oswego bass, LMB, and southern largemouth and northern largemouth. The largemouth bass is the state fish of Georgia and Mississippi, and the state freshwater fish of Florida and Alabama. Taxonomy The largemouth bass was first formally described as ''Labrus salmoides'' in 1802 by the French naturalist Bernard Germain de Lacépède with the type locality given as the Carolinas. Lacépède based his description on an illustration of a specimen collected by Louis Bosc near Charleston, S ...
