The river, in its upper reaches, supports a wild brown trout population and the occasional grayling. Chub and perch dominate the middle reaches around Stamford, with pike, perch, zander, roach, bream, rudd, ruffe, gudgeon and eels inhabiting the lower lengths around Spalding. A collaboration between the Welland Rivers Trust, the Wild Trout Trust and the Environment Agency has resulted in the construction of a rock ramp, to allow migrating sea trout to pass up the river beyond the weir on the Maxey Cut, which was acting as a barrier. Some 300 tons of rock, with 50 tons of finer material forming a top layer, were used to create the ramp.

The river holds a variety of fish species, including roach, dace and chubb. White-clawed crayfish are known to be in the river, which puts them at risk, as invasive species of crayfish are known to be in the Welland.
River Chater | Wildlife
Wildlife in the river varies along its length, the faster headwaters being a habitat for trout and the slower lower reaches for perch. The estuary conditions and flat landscapes beyond Fosdyke favour wading birds and migratory species.
River Welland | Introduction
The river, in its upper reaches, supports a wild brown trout population and the occasional grayling. Chub and perch dominate the middle reaches around Stamford, with pike, perch, zander, roach, bream, rudd, ruffe, gudgeon and eels inhabiting the lower lengths around Spalding. A collaboration between the Welland Rivers Trust, the Wild Trout Trust and the Environment Agency has resulted in the construction of a rock ramp, to allow migrating sea trout to pass up the river beyond the weir on the Maxey Cut, which was acting as a barrier. Some 300 tons of rock, with 50 tons of finer material forming a top layer, were used to create the ramp.
River Welland | Wildlife
The finer material ensures that water mainly flows over the ramp, rather than through it. The ramp also enables young eels or elvers to move up the river, and provides habitat for stone loach and bullheads. Large numbers of swans and geese use the river around Crowland, and out to sea. Smaller populations of each can be seen around the Stamford Meadows, and further upstream.
River Welland | Wildlife
Otters and kingfishers were seen on the River Welland in 2015.
Lubenham | Events
The lake is stocked with brown trout and rainbow trout, but there is a large head of coarse fish populated by water pumped in from the River Welland and River Nene, species include roach, bream, pike, zander, perch, eel, wels catfish and carp.
Rutland Water | Wildlife
The river provides habitat for most of the species of coarse fish that can be found in Britain. It is known for the unusually large sea trout that migrate up the river each year to spawn. There are also populations of pike and more recently carp, both of which can exceed in weight. Other species include barbel, roach, dace, rudd, perch, chub, bream and tench. The Sheffield and Batts Bridge tributaries have small populations of pumpkinseed, which have escaped from on-line fish ponds, and since 2009 a few catfish have appeared in the river at and upstream of Lewes. Rarer breeds which inhabit the river include grayling, stone loach, river lampreys, and bullhead, which are a species under threat on an international scale.
River Ouse, Sussex | Ecology and wildlife
A total of 16 species of fish are found in the river including; the glassfish, Macleay's glassfish, fork-talked catfish, fly-specked hardyhead, mouth almighty, spangled perch, barramundi, oxeye herring, rainbowfish, exquisite rainbowfish, Northern trout gudgeon, bony bream, catfish, and the seven-spot archerfish. A large number of crocodiles—both saltwater and fresh—inhabit the river. Wild cattle and bush pigs can be found in the surrounding countryside.
Fitzmaurice River | Fauna
The area of the headwaters of the Tweed would have been frequented by wild boar in Anglo-Saxon times. The other example of wella in the watershed is "Twitchell". Brook Farm, west of Stoke Golding takes its name from the unnamed stream running north towards the Tweed at the foot of Ambion Hill.
River Sence | Names related to the watercourses
The site also includes part of the fast-flowing Gilwiskaw Brook. The river has nationally significant populations of two species of freshwater fish, the spined loach and the bullhead. Vegetation is sparse in the upper reaches as the stream is fast-flowing, but there are stands of floating sweet-grass, and the gravel areas provide favourable conditions for the bullhead to spawn. The freshwater white-clawed crayfish Austropotamobius pallipes is also found in the river as is the otter, both having a restricted range in the East Midlands.
River Mease SSSI | Introduction
The river is a designated site of special scientific interest due to the fish that it supports. Of particular interest are the resident populations of spined loach ("Cobitis taenia") and European bullhead ("Cottus gobio") (two internationally notable species of native freshwater fish with a restricted distribution in England), white-clawed crayfish ("Austropotamobius pallipes") and European otters ("Lutra lutra"). The most numerous fish in the river are chub and roach; with dace, pike, perch and gudgeon also recorded. The river's wildlife is highly sensitive to pollution and fish numbers have fallen since 2007.
River Mease | Wildlife
The Ise contains many varieties of coarse and game fish, including roach, perch, barbel and chub. It is also the only watercourse within Northamptonshire to contain grayling (thymallus thymallus).

Padbury Brook is home to fish such as the stone loach ("Barbatula tarantula"), spined loach (" Cobitis taenia"), the common minnow ("Phoxinus phoxinus"), the common roach (Rutilus rutilus), the european bullhead ("Cottus gobio"), and the three-spined stickleback ("Gasterosteus aculeatus"). Larger fish including european chub ("Squalius cephalus"), European perch ("perca fluviatilis") and European eel ("Anguilla anguilla") are also resident in the river. There are also signal crayfish ("Pacifastacus leniusculus") in the river with most of the crayfish being small in size with a small number of larger ones. There also be a range of other wildlife such as swans, ducks, voles and myriad types of water insects.
Padbury Brook | Wildlife
Fish species found in the river include trout, perch, carp, roach. Also present are water scorpions, snails, caddisfly larvae, fish fry, red-eared sliders, rare snakes, crayfish, leeches and dragonfly. Plants include bamboo species and aquatic equisetopsida.
Fave | Flora and fauna
The river has had a chequered history with regard to its water quality and suffered from pollution, particularly in the 1960s, probably due to the rapid expansion of nearby Bracknell and inadequate sewage treatment by the works at Whitmoor Bog and Ryemead Lane, Winkfield. However, in recent decades things have improved and the river now contains a large population of small chub, along with some roach and gudgeon though it seems to have limited appeal to anglers. Other fish present are three-spined sticklebacks and stone loach, and the riparian fauna includes kingfisher, grey heron (especially around Warfield House lake), grey wagtail and mink.
The Cut, Berkshire | Ecology
Fish species include brown trout, three-spined stickleback, nine-spined stickleback, Atlantic salmon, stone loach, common bream, roach, perch and lamprey.

The River Welland, with its tributaries, form a river system with a catchment area of . Within this area, of waterway are designated as "main river", and are therefore managed for flood control by the Environment Agency under the River Welland Catchment Flood Management Plan (CFMP). Of this total, the below Spalding are tidal, and have sea walls to protect the adjacent land from flooding, while are fresh water, but run through low-lying land, and are therefore embanked. Within the catchment area, are below sea level, and would be flooded without such defences. The basin runs in a broadly south-west to north-east direction, with an extension to the north around the West Glen and East Glen rivers.
River Welland | Geography
The river is stocked with brown trout, and also contains wild grayling, eels, stone loach, minnow, three-spined Stickleback and flounder. A few sea-trout run the river, and occasional Atlantic salmon are reported, although those from which scale samples have been obtained have turned out to be from other catchments. Until the weirs are either demolished or furnished with effective fish-passes, there is little chance of a population of salmon establishing themselves in this river again. Roe deer, badgers, otters and other mammals are occasionally seen. The river and its environs are the haunt of a wide variety of woodland and water birds, including kingfisher, grey heron, pied wagtail, great spotted woodpecker and white-throated dipper.
Water of Leith | Wildlife
Otters, salmon, kingfishers, water rail and snipe are often seen in and around the river and the reedbeds either side. A footpath runs along the western edge of the river allowing the general public to view the wildlife.
Sladesbridge | Flora and fauna
A count of the fish in the rivers and floodplain lakes showed nine species - Chub, Dace, Striped bystranka, Common roach, Gudgeon, Tench, Ide, Loach, and Trout - accounting for 95% of the catch. In recent years, the park reports crayfish in the rivers, described as an indicator of improving water cleanliness. Birds of prey include the near-threatened Pallid harrier and the vulnerable Greater spotted eagle.

The underlying geology consists of Lias clays at the western end of the catchment, with Lincolnshire limestone in the centre, including the valleys of the Glen. The eastern third is mostly alluvial soils, and it is this part that relies on artificial pumping to prevent flooding. Rainfall over the area varies between per year, which is quite light, and because the land is efficiently drained during the winter months, there are few reserves, making the area prone to drought in the summer months. For much of its length the Welland forms the county boundary between Northamptonshire and Leicestershire or Rutland, and lower down between Lincolnshire and Cambridgeshire.
River Welland | Geography
Among the medieval forms of the name 'Welland' is Weolod; the river could have thus been named from its silty nature. In contrast, the Glen flowed from clays and limestone. Areas with clay-based soils tended to remain as woodland whilst the limestone areas provided grassland for pasture. Consequently, the River Glen did not carry much sediment. The modern Welsh for clean is "glân". The relative amounts of silt deposited in the fens around Maxey and around Thurlby respectively, by the two rivers, support this view.
River Glen, Lincolnshire | Naming
Recorded reptile species are Himalayan pit viper ("Gloydius himalayanus" syn. "Ancistrodon himalayanus") (common) and Boulenger's keelback ("Hebius parallelum"). In the Mandakini River, fishes recorded include Schizothorax sp., mahseer Tor tor, Labeo spp., Gara spp., Barilius spp., Nemacheilus sp. nov., Glyptothorax spp. and Balitora brucei.

Fish in the river include three-spined stickleback, bullhead, stone loach, brown trout, sea trout, brook lamprey, roach, rudd, perch, eel, pike, gudgeon, carp and tench.
River Glaven | Fish
The River Welland is a lowland river in the east of England, some long. It drains part of the Midlands eastwards to The Wash. The river rises in the Hothorpe Hills, at Sibbertoft in Northamptonshire, then flows generally northeast to Market Harborough, Stamford and Spalding, to reach The Wash near Fosdyke. It is a major waterway across the part of the Fens called South Holland, and is one of the Fenland rivers which were laid out with washlands. There are two channels between widely spaced embankments with the intention that flood waters would have space in which to spread while the tide in the estuary prevented free egress.
River Welland | Introduction
The earliest known list of fish from the River Trent was from 1641. Although the list contains thirty names, one of them is not a fish by modern standards, but an edible crustacean, the Crayfish. The list also includes some fish names that no longer exist in modern English, such as "Frenches" and "Lenbrood"; these species are therefore currently unidentifiable. The 1641 list of 30 species (verbatim, note antique spelling of some names): "Barbet, Bream, Bullhead, Burbolts, Carp, Chevin, Crayfish, Dates, Eel, Flounder, Frenches, Gudgeon, Grayling, Lampern, Lamphrey, Lenbrood, Loach, Minnows, Pickeral, Pinks, Perch, Roach, Ruff, Salmon, Shad, Smelt, Sticklebats, Sturgeon, Trout, Whitling".

Crayfish are very common in parts of the river. However, most, if not all, are now the alien American signal crayfish, having escaped from crayfish farms, which has replaced the native white-clawed crayfish in most southern rivers, although a small population still survives in the River Lambourn. And not forgetting the foundation to supporting this varied wildlife food chain, there are the insects, many hundreds of species, common and rare, that can be found in and around the River Kennet. There are large hatches of mayflies, whose long-tailed, short-lived adults are a favourite food of trout; many species of water beetle and insect larvae.
River Kennet | Wildlife
The Lister's river snail (Viviparus fasciatus) is abundant, and hog louse is also present.

Marsh crocodiles ("Crocodylus palustris"), gharials ("Gavialis gangeticus") and other reptiles are also found in the region. Local crocodiles were saved from extinction by captive breeding programs and subsequently re-released into the Ramganga river. Several freshwater terrapins and turtles like the Indian sawback turtle ("Kachuga tecta"), brahminy river turtle ("Hardella thurgii"), and Ganges softshell turtle ("Trionyx gangeticus") are found in the rivers. Butterflies and birds of the region include red helen ("Papilio helenus"), the great eggfly ("Hypolimnos bolina"), common tiger ("Danaus genutia"), pale wanderer ("Pareronia avatar avatar"), jungle babbler, tawny-bellied babbler, great slaty woodpecker, red-breasted parakeet, orange-breasted green pigeon and chestnut-winged cuckoo.

The Ain is very rich in fish, including trout, in particular "Salmo trutta fario"; grayling, especially the common grayling "Thymallys thymallus"; pike, perch, barbel, bream, carp, tench, roach, Eurasian minnow, chub and loach. Numerous birds populate the river's banks: duck, egret, swans, heron, and snipe. Beavers are also present and construct numerous dams while wild boar and roe deer are found in the woods and forests bordering the stream. Otters have once more been seen since 2003, so demonstrating a general improvement in the quality of the waters.
Ain (river) | Fauna
There are also populations of bullhead, eel, lamprey, minnow and stone loach. There has been some concern about declining fish stocks, thought to be partly caused by soil erosion, leading to silt and sediments being deposited on the river bed, which has been exacerbated by low flows in the river. Parts of the lower river support the same types of fish, but there are areas, particularly immediately upstream of weirs, where the major species are bream, pike and roach, with chubb, dace and perch on the lowest reaches. In order to assist the movement of fish along the river, particularly those that migrate to the headwaters to spawn, fish passes have been constructed around the gauging stations.
River Rother, West Sussex | Hydrology
Like many rivers in the south of England, non-indigenous mink and signal crayfish are present.
River Whitewater | Introduction
The Lyreen has a modest fish population, with seven species detected in 2011, primarily minnow, brown trout and stone loach. The Baltracey held four species in the same study, primarily stickleback. In the angle of the confluence of the Lyreen and the Rye Water, a coarse fishing and carp fishery was built, with two ponds added to an already existing angling pond.
Lyreen River | Wildlife
The river supports a wide variety of fish including barramundi and mangrove jack. The occasional salt water crocodile is also spotted in the river. Bird species such as black swans, the striated heron, Australian bustard and bush stone-curlew can be found along the river's banks.
Ashburton River (Western Australia) | Fauna
The river is a habitat for a variety of fish including brown trout, common dace, the gudgeon "Gobio gobio", stone loach and common minnow. There is an unusual isolated population of dormice in the Wych Valley, as a result of an introduction of animals in 1996/7.

Blyth River (Northern Territory) | Fauna
The fish species present vary along the river's length. The lower reaches (near Reddish Vale Country Park) are home to coarse fish such as gudgeon ("Gobio gobio"), chub ("Leuciscus cephalus"), and roach ("Rutilus rutilus"); pike ("Esox lucius") and perch ("Perca fluviatilis") are also present. The upper reaches (above Ashton) support brown trout ("Salmo trutta") and smaller numbers of some coarse fish. The populations are self-sustaining. Migratory fish such as Atlantic Salmon and Sea-trout cannot navigate the river as the weir at Reddish Vale is too tall and has no fish pass. Furthermore, are all declared as salmonid waters by statute, and as such have set physical and chemical water quality objectives.
River Tame, Greater Manchester | Fauna
The river supports a number of habitats, and is described as a high quality watercourse. The river itself is a habitat for a number of species, including white-clawed crayfish and species of fish. The river also supports a number of other habitats, providing a source of water for communities of animals including the deer in the ancient deer park at Bradgate Park. The river is protected within a conservation area of the Leicestershire Wildlife Trust.

The Welland rises in the Hothorpe Hills in the parish of Sibbertoft, Northamptonshire and it issues at Spring Croft, Church Street. Sibbertoft sits astride one of the principal watersheds in England. Within , the small stream forms the border between Northamptonshire and Leicestershire. It flows westwards, before looping round, passing through the grounds of Hothorpe Hall in Theddingworth, now a conference centre, to flow generally eastwards through Lubenham to Market Harborough. One of the driveways to Thorpe Lubenham Hall is carried over the river by an early nineteenth century ashlar bridge which is a Grade II listed structure. To the east of Lubenham, the river passes Old Lubenham Hall, part of an H-plan house built in the late sixteenth century and modified in the early eighteenth century.

The fish species in the river include: walleye, sauger, yellow perch, northern pike, lake trout, lake whitefish, cisco, white sucker, shorthead redhorse, longnose sucker, lake sturgeon and burbot.
Rapid River (Churchill River tributary) | Fish species
The river supports a wild variety of fish species, including grayling and trout. Chub and dace inhabit the lower length below Newstead bridge in Stamford. There are attempts to re-introduce water voles in the area. There are concerns about non-native signal crayfish becoming dominant in the river, and reports of a deliberate introduction. The river has formed part of pilot control trials.

The river flows under two navigable aqueducts: the Welland Recreational Waterway and the new alignment of the Welland Canal. An important tributary of the river is Coyle Creek, a picturesque and thickly forested creek that flows into the river on the north bank. A stream of the river branches off shortly before its mouth. This canal quickly turns an open-cut hydropower channel through the city of Niagara Falls on its way to the Sir Adam Beck Hydroelectric Generating Stations in Queenston. It drains an area of . The International Control Dam, a weir in the Niagara River, causes the Welland River to reverse its direction twice a day when the flow of water over the Niagara Falls is reduced overnight and the water heads back up the river as far back as Wellandport.

Ambion is the name of a deserted village by a headwater of the Saint rising in Cadeby. It is recorded as Anabein (ca 1270), Anne Beame in the Hollinshead Chronicle (1576), Anbein (1622) and Amyon by John Hutton (1788). The name seems to derive from Old English Āna-bēam, a One-Beam bridge, probably the hamlet's means of crossing the stream towards Market Bosworth. It is claimed as the traditional site of the Battle of Bosworth. Barwell, Barwalle (1043), Barewelle (1086), sometimes pronounced ‘Barrull’. The first element is Old English bār, ‘boar’. Old English wella signifies a spring or stream In west Leicestershire, it seems to mean the stream issuing from a spring rather than the spring itself.
River Sence | Names related to the watercourses
The river contains over thirty species of fish, including the Rutilus, perch, gudgeon, European chub, burbot, trout, grayling, barbel, bream, spirlin and silver bream. The river is also a place of living of the rare specimens – sea trout, common minnow, european bullhead and vimba vimba. The Drawa also hosts buzzards, red algae, sponges, spargania and potamogeton.
Drawa | Flora and fauna
The river may still host trout, grayling, perch, chub, roach and dace. It held good populations of native crayfish until at least the 1980s. Its waters were used in cloth and woollen blanket making in Witney from mid 17th century. In 2007, it was among many of the district's rivers to flood. It flooded generally but perhaps most acutely in Witney, whose only bridge across the river was submerged. Some decline has been noted, especially in years of duly reported and fined untreated sewage from plants of Thames Water. The river after drier spells sees algae formations.

Vernatt's Drain passes through a sluice to join the river, while the sluice that protects the entrance to the River Glen is navigable, to allow boats to reach Tongue End, some upstream from its mouth. There are pumping stations for Sea Dike and Lords Drain, and the outfalls of the Risegate Eau and Five Towns drainage channels before the final bridge at Fosdyke is reached. After it is joined by the Holbeach River, it is bordered by salt marshes, and finally flows into The Wash at "The Cots" in "Fosdyke Wash". Beyond the river banks, much of the fertile arable land is composed of marine silt, which suits the bulb-growing for which Spalding is famous.

Coyle Creek is a small creek in the municipalities of Welland, Pelham, and West Lincoln in Ontario, Canada, that forms an important component of the Welland River watershed. The last section of the creek constitutes an oasis of wild habitat in an otherwise increasingly developed area; the upper section of the creek runs through a golf course. The creek contains numerous fish species, including largemouth bass, northern pike, crappie, channel catfish, sunfish, and various species of minnow. As well, mud puppies are present in the creek. The surrounding woods are home to a wide variety of wildlife, including beavers, which are comparatively rare in Southern Ontario due to habitat loss.
Coyle Creek | Introduction
The origin of the name for the river is unknown but appears to be Pre-English. In Old English the form was "Weolud" and may have changed to the Middle English form due to folk-etymology or Scandinavian influence. The Welland ("Weolud") is first mentioned in the "Anglo-Saxon Chronicle" for 921 AD. Richard de Rulos, who was Lord of Deeping Fen during the reign of William the Conqueror erected a strong embankment to prevent flooding of the meadows adjoining the river, which then became fertile fields and a pleasure garden. During the reign of Henry III (1207–1272), complaints were made that of the two channels below Crowland, the one to Spalding was more favourable to the passage of barges, but the Abbot of Crowland had obstructed and narrowed its course by planting willow trees.
River Welland | History
At least 250 different bird species have been spotted in and around the river. With a wide variety of habitats along the river course including wetlands, impoundments, grassland, scrubland, riverine forest, thornveldt, rocky outcrops and both rural and urban settlements, resulting in a diverse population of birds along its course. Some notable birds include African Fish Eagle, Martial Eagle, Black-breasted Snake Eagle, Secretarybird, Kori Bustard, Egyptian Goose and Meyer's Parrot.

The Tywi also contains brown trout, eels, pike, and a variety of small fish species, and is home to brook lampreys, river lampreys and sea lampreys. The Tywi has the distinction of having accidentally produced by far the biggest fish ever taken on rod and line in fresh water in Britain. This was a sturgeon ("Acipwienser sturio") weighing 388 lb (176 kg) and in length which was caught in the river near Nantgaredig by Alec Allen on 28 July 1932.
River Tywi | Fish
Some of the fishes caught in its waters are "Labeobarbus aeneus", "Barbus pallidus", "Barbus anoplus", "Myxus capensis", "Anguilla marmorata" and "Anguilla mossambica". "Labeobarbus aeneus" is an invasive species, now widely present in the river system.

The river has Indian balsam plants on its banks. It was previously polluted by the local hemp and flax industries and by sewage discharges, but the environment of the river has improved in recent years. Fish species found include the stone loach, brown trout and minnows. These in turn support wildlife such as kingfishers and otters. Conditions are healthy enough to support the parr of salmon and sea trout, which live in the river for two to five years before turning into smolt and returning to the sea; fish passes have been installed to facilitate this.

In 1751, Charles Deering provided a list of 34 kinds, under the title "An alphabetical list of all the fish catch’d in the River Trent". This listed read (verbatim); "Barbel, Bream, Bulhead, Burbot, Carp, Chub, Crayfish, Dace, Eel, Flounder, Grayling, Gudgeon, Lamprey, Lampern, Loach, Minnow, Muscle, Perch, Pike, Roach, Rud, Ruff, Salmon, Salmon Trout, Salmon Pink, Sand Eel, Shad, Smelt, Strickleback, Sturgeon, Stream Pink, Tench, Trout, and Whitling". This list also includes several unrecognizable fish. It also lists three different names for salmon, as well as "Whitling", which is a name for a young male trout, and "Muscle", which is probably a reference to freshwater mussels, formerly used as food in some areas.

This list of fish in the River Trent is a list of fish species that have been recorded from the River Trent, a major river in England that starts in Staffordshire, flows through the Midlands, and joins the River Ouse to form the Humber Estuary. The impressive diversity of fish species in this river has been known (and celebrated) since 1590, with poetry containing the earliest mention that the Trent contains 30 kinds of fish. The earliest actual list of fish in the river is from 1641. Over the centuries some species have since become locally extinct, and other species have been introduced.

The Afon Clun and Nant Dowlais contain minnow, stickleback, stone loach, lamprey, and eel. The species European bullhead ("Cottus gobio") were also present, until a pollution incident in 2000 CE (see "Industry" below). In addition, the Clun contains roach and chub. Among the species in the flood-meadows adjacent to the Afon Clun is the common orchid. The river's banks contain broadleaf woodland as well as invasive plants such as Himalayan balsam and Japanese knotweed. Several species of dragonfly and damselfly hunt on the river. Other species present include bats, badger, dormouse, otter, great crested newt and the marsh fritillary butterfly, of which bats, dormouse, otter and great crested newt are European Protected Species.

The source of the River Welland is in the parish and it issues as a spring at Spring Croft, Church Street. Sibbertoft sits astride one of the principal watersheds in England and the plateau of land towards Naseby contains the sources of four rivers flowing west, south and east. Coombe Hill Hollow, north of the village, is a Site of Special Scientific Interest.

The river is bounded on the north and west by a bank, while the New River, a drainage channel to the south and east of it, is bounded by another bank. The land between the channels forms Crowland High Wash, Crowland Fodder Lots and Cowbit Wash. The southern bank is variously named Corporation Bank, Wash Bank and Barrier Bank. These wash lands were designed to be flooded "in extremis", although the building of the Coronation flood relief channel has made this purpose obsolete.

The Allen had the strongest population of white clawed crayfish in Dorset and measures such as tree planting and slowing the flow of the river down were implemented to help the species. However, an outbreak of Crayfish Plague was discovered on the river in 2014 with at least 100 of the native species found dead in the river. The river also contains an abundance of macrophytes including the two most abundant taxa; common water-crowfoot ("Ranunculus aquatilis") and bur-reeds ("Sparganium"). As well as an abundance of brown trout the river is also home to minnow, dace, grayling, salmon, perch, roach, pike, bullhead and brook lamprey and the critically endangered European eel.

Until the 19th century, the Calder was home to large numbers of salmon but pollution from the textile and chemical industries along its banks led to the death of the salmon population by the mid 19th century. The last salmon on record was caught at Wakefield in 1850, however there is evidence that they are returning, with sightings on the lower river at Castleford in 2008 and alleged catchings much further upstream. Around Huddersfield, Mirfield and Wakefield are popular areas for coarse fishing, roach, perch, chub, dace, minnows, gudgeon, pike, bream and trout. However the areas upstream of Dewsbury are quickly becoming cleaner and more suited to game and specialised river cyprinids like Barbel as well as general coarse fish that are also doing very well.

Biologists have recently discussed many conservation methods. In 2013, an alien fish barrier was constructed across a section of the Noordhoeks River to keep "Micropterus" species from moving upstream from this section of river. Additionally, invasive spotted bass were removed mechanically from sections of the Thee river mechanically between 2010 and 2014. No known populations are currently within the boundaries of any provincial nature reserves.

It is endemic to the Western Cape Province of South Africa, where it was formerly widespread in the Olifants River and its tributaries. Its range has decreased throughout most of the 20th century, and by now it is apparently only found in the upper Olifants River as well as the Biedou, Doring, Driehoeks, Jan Dissels, Oorlogskloof, Ratels and Tra Tra Rivers. It is rather euryoecious, inhabiting a wide variety of small and large rivers. While young fish are common in pools in the foothills, adults will move further down to where the rivers enter the coastal plain and the water is deeper.

The Burstwick Drain extends for just over and drains an area of . Due to the agricultural nature of the land that it drains, the surface run-off from fields has contributed to the river's poor ecological status. The underlying geology of the region that the watercourse drains is glacial gravels, marshes and estuarine alluvium.

The river is classified as being heavily modified, and much work has been undertaken by the Environment Agency and local volunteers to raise the watercourses' standard. Work by the Yorkshire Wildlife Trust has seen the return of many animals such as otters and herons. They have also installed logs in the river around the lakes in Staveley to provide shelter for fish. Whilst the presence of Cyprinid fish and brown trout in the watercourse is "likely", despite the poor chemical composition of the water,the river is noted for its Himalayan Balsam and Giant Hogweed. Mink faeces have also been observed on the river.

Fish species found in the river include Small mouth Yellowfish ("Labeobarbus aeneus"), Orange River Mudfish ("Labeo capensis"), Moggel ("Labeo umbratus"), Sharptooth Catfish (Clarias gariepinus), Banded Tilapia ("tilapia sparrmanii"), Southern Mouthbrooder ("pseudocrenilabrus philander"), Three spot Barb (e"nteromius" trimaculatus), Chubbyhead Barb (e"nteromius" anoplus), Straight-fin Barb (e"nteromius" paludinosus), Western Mosquitofish (Gumbisa affinis), Common Carp (cyprinus carpio), Largemouth Bass (micropterus dolomieu), Swordtail (Xiphophorus hellerii), Smallmouth Bass (Micropterus salmoides), Grass Carp (Ctenopharyngodon idella), Rock Catfish (Austroglanis sclateri), Canary Kurper (Chetia flaviventris). No known sightings of the Largemouth Yellowfish (Labeobarbus kimberleyensis) have been recorded in the last 40 years in the upper and middle Mooi River or its tributaries but there's a strong possibility that they do occur in the river close to its mouth on the Vaal river.

The Tywi and surrounding valley (Dyffryn Tywi) are home to a very large variety of water and wetland birds. Among the more distinctive species found along the river are sand martins, common sandpipers, little ringed plovers, dippers, kingfishers and grey wagtails. Red kites and buzzards are numerous. Goosanders and cormorants prey on sea trout and salmon.

The Great Fish River originates east of Graaff-Reinet and runs through Cradock. Further south the Tarka River joins its left bank. Thence it makes a zig-zag turn to Cookhouse, from where it meanders down the escarpment east of Grahamstown before its final near-straight run to its estuary 8 km northeast of Seafield, into the Indian Ocean. The river is generally permanent, having water all year round, although its headwaters rise in an arid region, and the natural flow can be sluggish in the dry season beyond the ebb and flow of the tidal reaches; now, water from the Orange River system can be used to keep up its flow in dry periods.
