Perch is a common name for freshwater fish from the genus Perca, which belongs to the family Percidae of the large order Perciformes. The name comes from Greek: πέρκη, romanized: perke, meaning the type species of this genus, the European perch.
The common kingfisher, also known as the Eurasian kingfisher and river kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter.
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the International Ornithologists' Union (IOU) adopted a consensus taxonomy of seven genera. The great cormorant and the common shag are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly.
The great cormorant, known as the black shag or kawau in New Zealand, formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. It breeds in much of the Old World, Australasia, and the Atlantic coast of North America.
The European shag or common shag is a species of cormorant. It is the only member of the monotypic genus Gulosus. It breeds around the rocky coasts of western and southern Europe, southwest Asia and north Africa, mainly wintering in its breeding range except for the northernmost birds. In Britain this seabird is usually referred to as simply the shag. The scientific genus name derives from the Latin for glutton. The species name aristotelis commemorates the Greek philosopher Aristotle.
The ruffe, also known as the Eurasian ruffe or pope, is a freshwater fish found in temperate regions of Europe and northern Asia. It has been introduced into the Great Lakes of North America, reportedly with unfortunate results, as it is invasive and is reproducing faster than other species. Its common names are ambiguous – "ruffe" may refer to any local member of its genus Gymnocephalus, which as a whole is native to Eurasia.
The pygmy cormorant is a member of the Phalacrocoracidae (cormorant) family of seabirds. It breeds in south-eastern Europe and south-western Asia. It is partially migratory, with northern populations wintering further south, mostly within its breeding range. It is a rare migrant to western Europe.
The word panfish, also spelled pan-fish or pan fish, is an American English term describing any edible freshwater fish that usually do not outgrow the size of an average frying pan. It is also commonly used by recreational anglers to refer to any small game fish that can fit wholly into a pan for cooking but are still large enough to be legal. According to the Oxford English Dictionary, the term was first recorded in 1796 in American Cookery, the first known cookbook written by an American author.
The zander, sander or pikeperch, is a species of ray-finned fish from the family Percidae, which also includes perch, ruffe and darter. It is found in freshwater and brackish habitats in western Eurasia. It is a popular game fish and has been introduced to a variety of localities outside its native range. It is the type species of the genus Sander.
The yellow perch, commonly referred to as perch, striped perch, American perch or preacher is a freshwater perciform fish native to much of North America. The yellow perch was described in 1814 by Samuel Latham Mitchill from New York. It is closely related, and morphologically similar to the European perch ; and is sometimes considered a subspecies of its European counterpart.
The Eurasian otter, also known as the European otter, Eurasian river otter, European river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia and the Maghreb. The most widely distributed member of the otter subfamily (Lutrinae) of the weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others.
The little black cormorant is a member of the cormorant family of seabirds. It is common in smaller rivers and lakes throughout most areas of Australia and northern New Zealand, where it is known as the little black shag. It is around sixty centimetres long, and is all black with blue-green eyes.
The white-breasted cormorant is a species of cormorant closely related to the widely distributed great cormorant. While debate persists over whether it constitutes a distinct species or a regional variant of the great cormorant, its distinguishing features include a white breast and a preference for freshwater habitats among its subpopulations. The species should not be confused with the smaller and morphologically distinct endemic South Australian black-faced cormorant, which occasionally shares the common name "white-breasted cormorant".
Coregonus artedi, commonly known as the cisco, is a North American species of freshwater whitefish in the family Salmonidae. The number of species and definition of species limits in North American ciscoes is a matter of debate. Accordingly, Coregonus artedi may refer either in a narrow sense to one of the several types of cisco found e.g. in the Great Lakes, or in a broad sense to the complex of all ciscoes in continental North American lakes, Coregonus artedi sensu lato.
This is a list of the fauna of Finland. Finland borders Sweden to the west, Russia to the east, and Norway to the north, while Estonia lies to its south across the Gulf of Finland, allowing an ecological mix. Finland contains many species of mammals, birds, and fish, but only a few reptiles and amphibians. This article discusses all the vertebrate animals which can be found on Finland itself, not the oceans.
The Balkhash perch is a species of perch endemic to the Lake Balkhash and Lake Alakol watershed system, which lies mainly in Kazakhstan. It is similar to the other two species of perch, and grows to a comparable size, but has a slimmer build and is lighter in colour.
Gobio gobio, or the gudgeon, is a species of fish in the family Cyprinidae. This small fish is widely distributed in fresh-water streams and lakes across central and temperate Eurasia.
Harp Lake is an oligotrophic, single-basin lake in Ontario, Canada. The lake covers over 710,000 m2 and has a depth of 37.5 m. Harp Lake does have dimitic stratification and is a temperate lake. Additionally, Harp Lake does not have anaerobic conditions in the water column because it is a relatively deep lake. The water in Harp Lake has a pH of 6.3. This pH is caused by the presence of acids and the lack of alkaline bases.[3] Slightly acidic lakes normally have a granite or siliceous bedrock and they are poorly buffered. Also, these lakes commonly have calcium-poor soils or thin soils.
The Murrough Wetlands are a 15-kilometre (9.32 mi) long complex of coastal wetlands in County Wicklow, Ireland. The main wetland is centred around Broad Lough immediately north of Wicklow town. Broad Lough is a large estuarine lake that is cut off from the Irish Sea by a long, thin shingle ridge. Smaller, disconnected wetland areas such as the East Coast Nature Reserve and the Kicoole Marshes are also included in the complex. The Murrough Wetlands are the most extensive wetland area on the east coast of Ireland, and are an EU-designated Special Area of Conservation and Special Protection Area.
