Fish species

Available species

Arctic charr

: "Arctic char or Arctic charr (Salvelinus alpinus) is a cold-water fish in the Salmonidae family, native to Arctic, sub-Arctic and alpine lakes and coastal waters. It breeds in fresh water, and populations can be either landlocked or anadromous, migrating to the sea. No other freshwater fish is found as far north."

: "The Arctic char is closely related to both salmon and lake trout, and has many characteristics of both. Individual fish can weigh 20 lb (9.1 kg) or more with record-sized fish having been taken by angling in northern Canada, where it is known as iqaluk or tariungmiutaq in Inuktitut. Generally, whole market-sized fish are between 2 and 5 lb (0.91 and 2.3 kg). The flesh colour can range from a bright red to a pale pink."

: "The Asp is a European freshwater fish of the Cyprinid family. It is protected by the Bern Convention of endangered species and habitats (Appendix III). Asps are also on the IUCN Red List of endangered species."

: "Normally asps are between 10 to 80 centimeters in length, with some reaching 120 centimeters, and weighing up to 12 kg. It inhabits lakes and lower reaches of rivers and estuaries. In spring, in April–June, the asps migrates from lakes to streams for spawning. Spawning is triggered by the raise in temperature and usually starts at 6°C. The eggs attach to rocks, gravel and water plants. After around two weeks they hatch and the fry drifts down stream to calmer waters."

Baltic herring

: "The small-sized herring in the inner parts of the Baltic Sea, which is also less fatty than the true Atlantic herring, is considered a distinct subspecies (Clupea harengus membras) ("Baltic herring"), despite the lack of a distinctive genome. The Baltic herring has a specific name in many local languages (Swedish strömming, Finnish silakka, Estonian räim, silk, Livonian siļk, Russian салака, Polish sałaka, Latvian reņģes, Lithuanian strimelė) and is popularly considered distinct from herring."

Brook trout

: "The brook trout (Salvelinus fontinalis), sometimes called the eastern brook trout, is a species of fish in the salmon family of order Salmoniformes. In many parts of its range, it is known as the speckled trout or squaretail."

: "This species is green to brown in basic colour, with a distinctive marbled pattern (called vermiculations) of lighter shades across the flanks and back and extending at least to the dorsal fin, and often to the tail. A distinctive sprinkling of red dots, surrounded by blue haloes, occur along the flanks. The belly and lower fins are reddish in color, the latter with white leading edges. Often, the belly, particularly of the males, becomes very red or orange when the fish are spawning. The species reaches a maximum recorded length of 86 cm (33 in) and a maximum recorded weight of 6.6 kg (14.5 lb). It can reach at least seven years of age, with reports of 15 year old specimens observed in California habitats to which the species has been introduced. Typical lengths vary from 25 to 65 cm (10 to 26 in), and weights vary from 0.3 to 3.0 kg (0.7 to 7.0 lb)."

: The burbot (Lota lota) or bubbot is the only gadiform (cod-like) freshwater fish. Also known as mariah, the lawyer, and (misleadingly) eelpout, the burbot is closely related to the marine common ling and the cusk. It is the only member of the genus Lota.

: Like a cross between the catfish and the eel, the burbot has a serpentine-like body, but is easily distinguished by a single barbel on the chin. The body is elongated and laterally compressed with a flattened head and single tube-like projection for each nostril. The mouth is wide, with both upper and lower jaws consisting of many small teeth. Burbot have two soft dorsal fins: the first being low and short, the second being much longer. The anal fin is low and almost as long as the dorsal fin. The caudal fin is rounded, the pectoral fins are fan-shaped, and pelvic fins are narrow with an elongate second fin ray. Having such small fins relative to body size indicate a benthos lifestyle with low swimming endurance, unable to withstand strong currents. The circular or cycloid scales are very small, making it difficult to accurately age, and thus even more challenging to manage. The burbot is commonly confused with the close, ocean dwelling relative : the lingcod.

: "The chub (Squalius cephalus) is a European species of freshwater fish in the carp family Cyprinidae. It frequents both slow and moderate rivers as well as canals and still waters of various kinds. In North America this species is referred to as the European chub. Other names used for the species include round chub, fat chub, chevin, pollard."

: "Small chub are freely-biting fish which even inexperienced anglers find easy to catch. As they become larger, however, chub become more wary and are easily spooked by noise or visual disturbance. Consequently, large chub (in excess of 2 kg) are keenly sought by anglers who prefer to target specific fish."

: "The common dace (Leuciscus leuciscus), also known as the dace or the Eurasian dace, is a fresh- or brackish-water fish belonging to the family Cyprinidae. It is an inhabitant of the rivers and streams of Europe north of the Alps as well as in Asia. It is most abundant in France and Germany, and has also spread to Ireland where it is used as a bait fish. It will grow to a maximum length of 15¾ inches (40 centimeters), a maximum weight of 2.2 lb (1 kg), and may live for up to 16 years."

: "The dace is a lively, active fish, of gregarious habits, and exceedingly prolific, depositing its pale yellow eggs in the spring at the roots of aquatic plants or in the gravelly beds of the shallow, flowing streams it frequents. It poses a risk as a potential pest in some areas. In appearance it closely resembles the Roach in both size and shape, with the head and back of a dusky blue color and the sides of a shining silvery aspect, with numerous dark lines running along the course of the scales. The ventral and anal fins are white, tinged with pale red,; and the dorsal, pectoral and caudal tipped with black. The dace feeds on worms, insects, insect-larvae, snails, and also rarely on vegetable matter."

: "The grayling (Thymallus thymallus) is a species of freshwater fish in the salmon family (family Salmonidae) of order Salmoniformes. It is the type species of its genus. Native to the Palearctic ecozone, the grayling is widespread throughout northern Europe, from the United Kingdom and France to the Ural Mountains in Russia. While it was introduced to Morocco in 1948, it does not appear to have become established there."

: "The grayling grows to a maximum recorded length of 60 cm (24 in) and a maximum recorded weight of 6.7 kg (15 lb). Of typical Thymallus appearance, the grayling proper is distinguished from the similar Arctic grayling (T. arcticus arcticus) by the presence of 5–8 dorsal and 3–4 anal spines, which are absent in the other species; T. thymallus also has a smaller number of soft rays in these fins. Individuals of the species have been recorded as reaching an age of 14 years."

: "The ide (Leuciscus idus), or orfe is a freshwater fish of the family Cyprinidae found across northern Europe and Asia. It occurs in larger rivers, ponds, and lakes, typically in schools. The name is from Swedish id, originally referring to its bright color (compare the German dialect word aitel 'a kind of bright fish' and Old High German eit 'funeral pyre, fire')."

: "The body has a typical cyprinid shape and generally silvery appearance, while the fins are a pinkish red in varying degrees. The tail and backfin can be greyish. In older and bigger fish the body color can turn to yellow/bronze."

Lake trout

: "Lake trout (Salvelinus namaycush) is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish."

: "Lake trout are the largest of the charrs; the record weighed almost 46.3 kilograms (102 lb) (netted), and 15– to 40-pound fish are not uncommon."

: "Perca fluviatilis, commonly known as the European perch, perch, redfin perch or English perch, is a predatory species of perch found in Europe and Asia. The species is a popular quarry for anglers, and has been widely introduced beyond its native area, into Australia, New Zealand, and South Africa. They have caused substantial damage to native fish populations in Australia."

: "European perch can vary greatly in size between bodies of water. They can live for up to 22 years, and older perch are often much larger than average; the maximum recorded length is 60 cm (24 in). The British record is 2.8 kg (6 lb 2 oz), but they grow larger in mainland Europe than in Britain. As at Aug 2012, the official all tackle world record, as recognised by the International Game Fish Association stands at 2.9 kg (6 lb 6 oz) for a Finnish fish. Due to the low salinity levels of the Baltic, especially around the Finnish archipelago and Bothnian Sea, many freshwater fish live and thrive there. Perch especially are in abundance and grow to a considerable size due to the diet of Baltic herring."

: "The northern pike (Esox lucius, known simply as a pike in Britain, Ireland, most parts of the USA, or as jackfish in Canada or simply "Northern" in the Upper Midwest of the USA), is a species of carnivorous fish of the genus Esox (the pikes). They are typical of brackish and freshwaters of the northern hemisphere (i.e. holarctic in distribution)."

: "Northern pike are most often olive green, shading from yellow to white along the belly. The flank is marked with short, light bar-like spots and there are a few to many dark spots on the fins. Sometimes the fins are reddish. Younger pike have yellow stripes along a green body, later the stripes divide into light spots and the body turns from green to olive green. The lower half of the gill cover lacks scales and they have large sensory pores on their head and on the underside of the lower jaw which are part of the lateral line system. Unlike the similar-looking and closely related muskellunge, the northern pike has light markings on a dark body background and fewer than six sensory pores on the underside of each side of the lower jaw."

Rainbow trout

: "The rainbow trout (Oncorhynchus mykiss) is a species of salmonid native to tributaries of the Pacific Ocean in Asia and North America. The steelhead is a sea-run rainbow trout (anadromous) usually returning to freshwater to spawn after two to three years at sea; rainbow trout and steelhead trout are the same species. The fish are often called salmon trout.[1] Several other fish in the salmonid family are called trout; some are anadromous like salmon, whereas others are resident in freshwater only."

: "The species has been introduced for food or sport to at least 45 countries, and every continent except Antarctica. In some locations, such as Southern Europe, Australia and South America, they have negatively impacted upland native fish species, either by eating them, outcompeting them, transmitting contagious diseases, (such as whirling disease transmitted by Tubifex) or hybridization with closely related species and subspecies that are native to western North America (see Salmo marmoratus and Salmothymus obtusirostris salonitana)."

: "The roach (Rutilus rutilus), also known as the common roach, is a fresh- and brackishwater fish of the Cyprinidae family, native to most of Europe and western Asia. Note that name "roach" is not unique, but fishes called roach can be any species of the genera Rutilus and Hesperoleucus depending on locality. The plural of the term is also roach."

: "The roach is typically a small fish, often reaching no more than about 35 cm (14 inches). Maximum length is 45 cm. The body has a blueish silvery colour and becomes white at the belly. The fins are red. The number of scales along the lateral line is 39-48. The dorsal and anal fin has 12-14 rays. Young specimens have a slender build, older specimens get a higher and broader body shape. The roach can often be recognized by the big red spot in the iris above and beside the pupil. Colours of the eye and fins can be very pale however in some environments."

: "The common rudd Scardinius erythropthalmus is a bentho-pelagic freshwater fish, widely spread in Europe and middle Asia, around the basins of the North, Baltic, Black, Caspian and Aral seas."

: "Morphologically, this species is very similar to the roach (Rutilus rutilus), with which it can be easily confused. It can be identified by the yellow eye colour. The eye of the roach has a big red spot above the pupil, that can be more or less conspicuous. The rudd has an upturned mouth allowing it to feed easily at the top of the water. The placement of the dorsal fin is more to the rear which is even visible in very young fish. There are normally only one or two scales between the tip of the pelvic fins and the anal fins, while on the roach there are five. Also the skin of the rudd is yellowish green, while the roach is bluish on the flanks. Also the upturned mouth is visible even in young fish. Furthermore the rudd's number of soft rays in the dorsal fin (8–9 compared to 10–12). There can be confusion with the ide also, which has smaller scales however."

: "The Eurasian ruffe (also simply ruffe or pope), Gymnocephalus cernua, 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. Its common names are ambiguous – "ruffe" may refer to any local member of its genus Gymnocephalus, which as a whole is natively endemic to Eurasia."

: "The ruffe's colors and markings are similar to those of the walleye, an olive-brown to golden-brown color on its back, paler on the sides with yellowish white undersides. The ruffe is usually 4–6 inches (10–15 cm) long and will never exceed 10 in (25 cm), but is a very aggressive fish for its size. The ruffe also has a large, spiny dorsal fin likely distasteful to its predators. It also has two fins on top, the front fin has hard and sharp spines, the back fin has soft spines called rays. The most obvious features to recognize a ruffe are the ruffe's large, continuous dorsal fin and its slightly downturned mouth."

Silver bream

: "Blicca bjoerkna, known as the white bream or the silver bream, is a European species of freshwater fish in the Cyprinidae family."

: "The maximum weight a silver bream can reach is determined by habitat of course, but give the optimum conditions for fast, healthy growth, they have an absolute maximum upper limit approaching, or possibly just exceeding, 1.6 kilos, or 3.5 pounds. Fish that do not live in such rich environments may attain a weight of around 0.9 kilos, or 2 pounds, but most silver bream never exceed a weight of 0.45 kilos, or 1 pound, and in small ponds, may never achieve even .3 kilos, or 0.8 pounds."

Three-spined stickleback

: "The three-spined stickleback, Gasterosteus aculeatus, is a fish native to most inland coastal waters north of 30°N. It has long been a subject of scientific study for many reasons. It shows great morphological variation throughout its range, ideal for questions about evolution and population genetics. Most populations are anadromous (they live in seawater but breed in freshwater or brackish water) and very tolerant of changes in salinity, a subject of interest to physiologists."

: "The largest of all sticklebacks, it is usually 5 cm (2 in) long (but may reach, exceptionally, twice that length). The body is laterally compressed. The base of the tail is slender. The caudal fin has 12 rays. The dorsal fin has 10-14 rays; in front of it are the three spines that give the fish its name (though some individuals may have only 2, or 4). The third spine (the one closest to the dorsal fin) is much shorter than the other two. The back of each spine is joined to the body by a thin membrane. The anal fin has 8-11 rays and is preceded by a short spine. The pelvic fins consist of just a spine and one ray. All spines can be locked in an erect position, making the fish extremely hard to swallow by a predator. The pectoral fins are large, with 10 rays. The body bears no scales but is protected by bony plates on the back, flanks, and belly."

: "The brown trout (Salmo trutta) is an originally European species of salmonid fish. It includes both purely freshwater populations, referred to Salmo trutta morpha fario and S. trutta morpha lacustris, and anadromous forms known as the sea trout, S. trutta morpha trutta. The latter migrates to the oceans for much of its life and returns to freshwater only to spawn. Sea trout in the UK and Ireland have many regional names, including sewin (Wales), finnock (Scotland), peal (West Country), mort (North West England) and white trout (Ireland)."

: "The brown trout is normally considered to be native to Europe, but the natural distribution of the migratory forms may be, in fact, circumpolar. Landlocked populations also occur far from the oceans, for example in Greece and Estonia."

: "Coregonus albula, known as the vendace or as the European cisco, is a species of freshwater whitefish in the family Salmonidae. It is found in lakes in northern Europe, especially Finland, Sweden, Russia and Estonia, and in some lakes of the United Kingdom, northern Germany and Poland. It is found also in diluted brackish water in the Gulf of Finland and the Gulf of Bothnia of the Baltic Sea."

: "Vendace mainly feed on zooplankton, such as small crustaceans and their larvae. The fish live in schools made up of large groups of individuals. They lay their eggs on pebbly or sandy ground. The length of an adult is normally about 25 centimetres (9.8 in). The maximum age reached by this fish is about ten years."

: "In the broad sense, Coregonus lavaretus, referred to as the common whitefish or European whitefish, is widespread from central and northwest Europe to Siberia. Often called the C. lavaretus complex and considered as a superspecies, it encompasses many of the whitefish populations suggested by others to be locally restricted species (such as the British powan and the gwyniad or the Alpine gravenche, as well as distinct intralacustrine morphs and populations characterized by different feeding habits, gill raker numbers, growth patterns and migration behaviour."

: "Genetic studies suggest that the whitefish diversity within this complex is mostly of post-glacial origin.

: "Zander (Sander lucioperca, syn. Stizostedion lucioperca) is a species of fish from freshwater and brackish habitats in western Eurasia. It is closely related to perch. Zander are often called pike-perch as they resemble the pike with their elongated body and head, and the perch with their spiny dorsal fin. Zander are not, as is commonly believed, a pike and perch hybrid. In Europe, a second species (Sander volgensis) is limited to rivers in southern Russia and the basin of the Danube."

: "The zander is a common and popular game fish in Europe. It is often eaten, and it may reach 20 kg (44 lb) of weight, although typical catches are considerably smaller."
