Trout is a generic common name for numerous species of carnivorous freshwater ray-finned fishes belonging to the genera Oncorhynchus, Salmo and Salvelinus, all of which are members of the subfamily Salmoninae in the family Salmonidae. The word trout is also used for some similar-shaped but non-salmonid fish, such as the spotted seatrout/speckled trout.
The brown trout is a species of salmonid ray-finned fish and the most widely distributed species of the genus Salmo, endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced globally as a game fish, even becoming one of the world's worst invasive species outside of its native range.
The Atlantic salmon is a species of ray-finned fish in the family Salmonidae. It is the third largest of the Salmonidae, behind Siberian taimen and Pacific Chinook salmon, growing up to a meter in length. Atlantic salmon are found in the northern Atlantic Ocean and in rivers that flow into it. Most populations are anadromous, hatching in streams and rivers but moving out to sea as they grow where they mature, after which the adults seasonally move upstream again to spawn.
Sea trout is the common name usually applied to anadromous (sea-run) forms of brown trout, and is often referred to as Salmo trutta morpha trutta. Other names for anadromous brown trout are bull trout, sewin (Wales), peel or peal, mort, finnock (Scotland), white trout (Ireland), Dollaghan and salmon trout (culinary).
Salmo trutta fario, sometimes called the river trout, is a river-dwelling freshwater predatory fish from the genus Salmo of the family Salmonidae. It is one of the three main subspecies of the brown trout, besides sea trout and the lacustrine trout.
Garrison is a village near Lough Melvin in County Fermanagh, Northern Ireland. The Roogagh River runs through the village. In the 2021 census it had a population of 411 people. It is situated within Fermanagh and Omagh district.
Ferox trout is a variety of trout found in oligotrophic lakes/lochs of Ireland, England, Scotland and Wales. Ferox trout is a traditional name for large, piscivorous trout, which in Scotland feed largely on Arctic char. It has been argued to be a distinct species, being reproductively isolated from "normal" brown trout of the same lakes, particularly in Ireland. However, it is uncertain whether the ferox of different lakes are all of a single origin. This fish grows to a length of 80 centimetres (31 in) SL.
Lough Melvin is a lake in the northwest of the island of Ireland on the border between County Leitrim and County Fermanagh. It is internationally renowned for its unique range of plants and animals.
Ohrid trout or the Lake Ohrid brown trout is an endemic species of trout in Lake Ohrid and in its tributaries and outlet, the Black Drin river, in North Macedonia and Albania. Locally, the fish is known as охридска пастрмка in Macedonian and Koran or Korani in Albanian.
Dollaghan are a variety of brown trout native to Lough Neagh, Northern Ireland, and many of its tributaries. They are a potamodromous migratory trout spending much of the year in the lough, returning to the rivers in autumn to spawn. Dollaghan are much sought after by anglers in County Antrim, County Tyrone and County Londonderry due to their greater size in comparison to the non-migratory trout found in streams such as the Ballinderry River, Six Mile Water, Moyola River and River Main. They are often caught in the dark using methods very similar to that of fishing for sea trout, where it is surmised their name comes from an old Irish word for 'ghost'.. Many anglers regard them as an elusive species and call them 'sea trout of Lough Neagh'. Their weight varies greatly - from small fish of around 1/2 lb to large specimens of around 20 lb. There are three other strains of brown trout in Ireland: Gillaroo, Sonaghen and Ferox. The Dollaghan is thought to have evolved from sea trout which were land locked many years ago.
The Mexican golden trout is a species of fish in the family Salmonidae. The species is endemic to high-elevation headwaters of the Fuerte River, Sinaloa River, and Culiacán River drainages in the Sierra Madre Occidental in Mexico.
Salmo aphelios is a species of trout, a salmonid fish endemic to Lake Ohrid in North Macedonia and Albania in the Balkans.
Salmo marmoratus, the marble trout, is a species of freshwater fish in the family Salmonidae. It is characterized by a distinctive marbled color pattern and high growth capacity. The marble trout is found in only a handful of drainages and rivers of the Adriatic basin in Italy, Slovenia, Croatia, Bosnia and Herzegovina, and Montenegro, while in Albania, the species is considered most likely extirpated.
Salmo platycephalus, known as the flathead trout, Ala balik or the Turkish trout, is a type of trout, a fish in the family Salmonidae. It is endemic to southeastern Turkey. It is known only from one population, which occupies three streams, tributaries of the Zamantı River in the Seyhan River basin. The population itself is abundant, but subject to threat by habitat loss, since the range is small. Also, predation of juveniles by introduced rainbow trout may cause population decline. The species is classified as critically endangered.
Salmo cettii, or the Mediterranean trout, is a species of trout, a freshwater fish in the family Salmonidae. It lives in the Mediterranean region in Corsica, Sardinia, Sicily, and on the Italian mainland in the Magra drainage and further south. It is a nonmigratory fish which lives in streams and in karstic resurgences. It is smaller than 40 cm (16 in) in length. It is sometimes referred to Salmo trutta macrostigma, which depending on concept is either a more widespread Mediterranean taxon, or a taxon endemic to Algeria.
Salmo rhodanensis, or the Rhône trout, is a salmonid fish, a putative species of trout resident in the Rhône river drainage in France and Switzerland. It was previously considered as belonging to Salmo trutta. Salmo rhodanensis is an exclusively freshwater fish, and is uniquely characterized by four broad black bars on its body: behind gill opening, under dorsal base, above anal fin origin, and at the base of the tail.
Salvelinus grayi, also called Gray's char[r], Lough Melvin char[r] or freshwater herring, is a species of lacustrine char in the family Salmonidae.
Salmo nigripinnis, also known as the sonaghen, is a species of fish within the family Salmoninae.
Salmo farioides, commonly known as the West Balkan trout, the Adriatic brown trout, or the Balkan brook trout, is a species of ray-finned fish found in the Balkans, including Albania, Croatia, North Macedonia, among others. It is an important fish in numerous rivers and lakes throughout the region. Identification of Salmo farioides is difficult due to the high degree of endemism in the western Adriatic and Mediterranean area, particularly among salmonid species, and because of high phenotypic diversity among trout populations specifically.
Salvelinus struanensis, commonly known as Scottish char, is a species of freshwater fish in the salmon family. It is found in the Loch Rannoch and Loch Ericht in Scotland, United Kingdom.
