Lough Melvin
Lough Melvin ( ; ) is a lake in the northwest of the island of Ireland on the border between County Leitrim (in Ireland) and County Fermanagh (in the United Kingdom). It is internationally renowned for its unique range of plants and animals. Ecology The water quality was reported to be excellent with an oligotrophic rating. The ecology of Lough Melvin, and other Irish waterways, remain threatened by curly waterweed, zebra mussel, and freshwater clam invasive species. Fishes and angling Lough Melvin is one of Ireland's famous angling loughs offering the chance of spring salmon from February to May, grilse from May to July and gillaroo, sonaghan and ferox trout throughout the season. Lough Melvin is also home to an endemic species of char, the Melvin charr or Gray's charr ('' Salvelinus grayi''). A ghillie or boatman is strongly recommended to anglers unfamiliar with the lake. Gillaroo trout Lough Melvin is home to the gillaroo or ''Salmo stomachius'', a species of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County Leitrim
County Leitrim ( ; gle, Contae Liatroma) is a county in Ireland. It is in the province of Connacht and is part of the Northern and Western Region. It is named after the village of Leitrim. Leitrim County Council is the local authority for the county, which had a population of 35,087 according to the 2022 census. The county encompasses the historic Gaelic territory of West Breffny () corresponding to the northern part of the county, and Muintir Eolais or Conmaicne Réin, corresponding to the southern part.

Grilse
Salmon () is the common name for several commercially important species of euryhaline ray-finned fish from the family Salmonidae, which are native to tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus ''Oncorhynchus'') basin. Other closely related fish in the same family include trout, char, grayling, whitefish, lenok and taimen. Salmon are typically anadromous: they hatch in the gravel beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn (biology), spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray and spawn in different freshwater systems; the percent of straying depends on the species of salmon. Homing behavior has been shown to depend ...

Chaoborus
''Chaoborus'' is a genus of midges in the family Chaoboridae. The larvae are known as glassworms because they are transparent. They can be found commonly in lakes all over the world and can be up to . The adults are sometimes called phantom midges or lake flies. Appearance Glassworms are almost entirely transparent, except for pairs of black kidney-shaped structures in the front and the back of the body. These dots are the air sacs. They use these air sacs to migrate up and down in lakes. Glassworms breathe through the end of their abdomen and have two small eyes at the front of their bodies. Behavior ''Chaoborus'' adults do not bite mammals or suck blood. Larvae live in open waters and even sediments, where there may be little oxygen for them to breathe. In some lakes they can be found as deep as . In these deep anoxic waters they can avoid predation more easily than near the surface. They get around the fact that a normal air filled invertebrate tracheal system would fail at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chironomid
The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae. The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects; some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They are called "sand flies", "muckleheads", "muffleheads", "Canadian so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladocera
The Diplostraca or Cladocera, commonly known as water fleas, are a superorder of small crustaceans that feed on microscopic chunks of organic matter (excluding some predatory forms). Over 1000 species have been recognised so far, with many more undescribed. The oldest fossils of diplostracans date to the Jurassic, though their modern morphology suggests that they originated substantially earlier, during the Paleozoic. Some have also adapted to a life in the ocean, the only members of Branchiopoda to do so, even if several anostracans live in hypersaline lakes. Most are long, with a down-turned head with a single median compound eye, and a carapace covering the apparently unsegmented thorax and abdomen. Most species show cyclical parthenogenesis, where asexual reproduction is occasionally supplemented by sexual reproduction, which produces resting eggs that allow the species to survive harsh conditions and disperse to distant habitats. Description They are mostly long, with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmonid
Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes . It includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), chars, freshwater whitefishes, graylings, taimens and lenoks, which are collectively known as the salmonids ("salmon-like fish"). The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus ''Salmo'', is also the source of the family and order names. Salmonids have a relatively primitive appearance among the teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They have slender bodies, with rounded scales and forked tails, and their mouths contain a single row of sharp teeth. Although the smallest species is just long as an adult, most are much larger, with the largest reaching . All salmonids spawn in fresh water of upper reaches of rivers and creeks, but in many cases, the fish spen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irish Language
Irish ( Standard Irish: ), also known as Gaelic, is a Goidelic language of the Insular Celtic branch of the Celtic language family, which is a part of the Indo-European language family. Irish is indigenous to the island of Ireland and was the population's first language until the 19th century, when English gradually became dominant, particularly in the last decades of the century. Irish is still spoken as a first language in a small number of areas of certain counties such as Cork, Donegal, Galway, and Kerry, as well as smaller areas of counties Mayo, Meath, and Waterford. It is also spoken by a larger group of habitual but non-traditional speakers, mostly in urban areas where the majority are second-language speakers. Daily users in Ireland outside the education system number around 73,000 (1.5%), and the total number of persons (aged 3 and over) who claimed they could speak Irish in April 2016 was 1,761,420, representing 39.8% of respondents.

Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wildlife, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghillie
''Gillie'' or ''ghillie'' is an ancient Scottish Gaelic, Gaelic term for a person who acts as a servant or attendant on a fishing, hunting, deer stalking or falconry, hawking expedition, primarily in the Scottish Highlands or on a river such as the River Spey. In origin it referred especially to someone who attended on his male employer or guests. This position still exists in some Highland locations , such as the Isle of Skye, according to the BBC. They are no longer "manservants" or "attendants" and do not carry Chiefs across rivers as in the distant past; today, they "manage the wilderness and guide travellers through it". Etymology The origin of this word dates from the late 16th century, from the Scottish Gaelic ''gille'', "lad, servant", cognate with the Irish language, Irish ''giolla''. Historically, the term was used for a Scottish Highlands, Highland chief's attendant. A ghillie-weetfit, a term now obsolete (a translation of "gille-caisfliuch", from the Gaelic ''cos' ...

Salvelinus Grayi
''Salvelinus grayi'', also called Gray's char ''r Lough Melvin char ''ror freshwater herring, is a species of lacustrine char in the family Salmonidae. It is only found in Lough Melvin, Ireland; numbers of fish are declining and the species is considered critically endangered by the International Union for Conservation of Nature. Taxonomy Name The describer, Albert Günther, named the fish after his longtime colleague John Edward Gray. The English word "char is thought to derive from Old Irish ''ceara''/''cera'' meaning " loodred," referring to its pink-red underside. This would also connect with its Welsh name ''torgoch'', "red belly." Description This species grows to an average length of and a weight of . Compared to other members of the ''Salvelinus'' genus, it has a deeper body that is more laterally compressed, a shorter caudal peduncle and larger scales. It can be distinguished from other char by the whitish spots on upper flank and caudal and dorsal fins. Biology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salvelinus
''Salvelinus'' is a genus of Salmonidae, salmonid fish often called char or charr; some species are called "trout". ''Salvelinus'' is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea. Most char may be identified by light-cream, pink, or red spots over a darker body. Scales tend to be small, with 115-200 along the lateral line. The pectoral, pelvic, anal, and the lower aspect of caudal fins are trimmed in snow white or cream leading edges. Many members of this genus are popular sport fish, and a few, such as lake trout (''S. namaycush'') and arctic char (''S. alpinus'') are objects of commercial fisheries and/or aquaculture. Occasionally, such fish escape and become invasive species. Deepwater char are small species of char living below 80 m in the deep areas of certain lakes. They are ...
