Fish Facts

That there are many who believe that it is unnecessary with theoretical knowledge (fish facts) about fish and water can not be more wrong. It is a fact that such knowledge not only gives a much greater insight for fishing opportunities, but also lays the foundation for a more fun and usually a more rewarding fishing. These fish facts may even be essential to you in difficult circumstances whatsoever should be given the chance to feel the fish on the hook.

Fact is that you can spend a lifetime at the same fishing grounds and still not be real wise on what it is that really gets the fish to bite in a given situation at a given bait. Though at the same time it's part of sport fishing excitement and fascination. To think how boring it would be to be sure where the fish are and to always know which bait will chop on.

All fish are cold-blooded, which means their metabolism and other body functions adapted to the temperature of the water in which they live. Because of the fish gets dull and less flexible when the water temperature drops, while reducing food intake to a minimum in cold water. The colder the water the less eat it even though there is plenty of food around, which is the main reason why it tends to be more difficult to attract the fish to bite, the lower the water temperature is.

Trivseltemperatur

All fish species have their particular comfortable temperature, which means that the fish are most active within a certain temperature range. Too cold or warm water in relation to the comfortable temperature affects fishing negatively, which means that with the right fish facts can your luck be greater.  Obviously trying to fish itself to actively seek out areas or water layer where the temperature of the comfort point of view is perceived as more pleasant. When the water cools down, For example, during the fall and winter, seek out the fish to the temporary warmest places, usually near bottom. In the spring, when the water heats up quickly in the surface and in shallow bays, looking on to these relatively warm places. In summer, however,, where surface water is warmest, pulls the fish back to deeper, cooler water, until it reaches a level where the water temperature is favorable for its comfort temperature. So to increase the chances of catching one should always try to fish in the water layer where the water temperature is consistent with the current species' comfort temperature.

To be able to orient themselves in life are using the fish, just like us humans, Sina Sinne. These are sight, hearing, succeed, taste and touch. In addition, all fish species a lateral line, a kind of auditory organs that runs from head to tail. With this, the fish can not only feel pressure waves in the water, but also determine their direction. This lateral line is a great aid to fish in their search for food, for example at night, at great depths and in turbid water.

Most interesting fish species for anglers chasing however food primarily by sight. Fish eyes are designed so that it can actually see in two directions simultaneously, to assess the exact distance the fish can also fix an object with both eyes. This field of view, Touted as the fish's window is right in front of the fish and is quite narrow and only suitable for relatively short distances.

Perch

Perch playing in shallow water in early spring, then pulls out to deeper water. While the perch in shallow lakes and rivers for a vagabond like existence, found in the larger lakes pelagic perch hunting in deeper waters and a typical groundwater perch encountered along the beaches almost all year.

Perch thrive in clear waters, because it is a pure predator. Murky waters, however, perch often better play facilities and no eggs or larvae are detected as easily by other fish. Therefore, usually one of the many colored water find a large population of småabborrar, so-called thousand brothers. The perch is gregarious and lives almost everywhere in small or large schools. They gather on the deep edges, soil banks, åarnas in deeper parts, at bridge piers or jetties. The perch has a relatively high comfortable temperature of 18-20 degrees, although it makes certain temperature-dependent migrations.


ASP

Aspen belongs to the family of carp fish,,sv,The species occurs in southern and central Sweden and is found in rivers and streams,,sv,Aspen can be very large plant,,sv,the largest specimens are over,,sv,meters long and can weigh over,,sv,Prohibition on fishing for asp is why in April-May in all the rivers which flow into Lake Hjälmaren,,sv,Vänern and Malaren,,sv,In Sweden, aspen mainly in the Great Lakes Vänern,,sv,Hjälmaren and Mälaren or rivers which flow into these,,sv,Smaller stocks are in the lake system Roxen,,sv,Boren Edsån and Glan,,sv,Smaller stocks are also in the river,,sv. Arten förekommer i Götaland och Svealand och finns i älvar och åar. Aspen kan bli mycket storväxt, de största exemplaren blir över 1 meter långa och kan väga över 12 kg. Fiskeförbud efter asp råder under perioden april–maj i alla vattendrag som mynnar i Hjälmaren, Vänern och Mälaren.

I Sverige finns asp huvudsakligen i de stora sjöarna Vänern, Hjälmaren och Mälaren eller vattendrag som mynnar i dessa. Mindre bestånd finns i sjösystemet Roxen, Boren Edsån och Glan. Mindre bestånd finns även i Emån, Dalälven and Göta.,,sv,The status of stocks in the river and Dalälven is uncertain and may be extinct,,sv,It's a leklokal in Edsån in Rotebro where aspen can be seen playing every spring,,sv,Asp has also been found in Lake Ärlången in Östergötland,,sv,Aspen is different from the other Swedish carp fish by being a pure predator,,sv,For young aspens, the diet probably by plankton and later by smaller animals like worms and snails before aspen becoming fish diet,,sv,Probably prefer aspen smaller fish as bleak,,sv,Roach and smelt,,sv[21] Beståndens status i Emån och Dalälven är osäkra och kan vara utrotade. Den finns en leklokal i Edsån i Rotebro där aspen kan ses leka varje vår. Asp har även påträffats i sjön Ärlången i Östergötland

Aspen skiljer sig från de övriga svenska karpfiskarna genom att vara en utpräglad rovfisk. För unga aspar består födan troligen av plankton och senare av mindre djur som maskar och snäckor innan aspen övergår till fiskdiet. Troligen föredrar aspen mindre fiskar som löja, mört och nors.

Aspen migrate up the rivers to spawn in April-May,,sv,The game starts when the water temperature exceeds,,sv,°C,,en,which in Uppland often coincides with the last week of April,,sv,The game takes place on flowing and cascading places with rocky bottom, often richly wooded with water moss,,sv,Pisces stand side by side during the game,,sv,sometimes up to ten individuals beside each other,,sv,Aspen,,en,uncertain whether it is male or female,,sv,can sometimes be seen holding a territory which it strongly defends the attacks on fish that gets too close,,sv.

Leken sker på strömmande och forsande platser med stenig botten som ofta är rikligt beväxt med vattenmossa.


Pike

When the water in the spring heated seek out the pike in play. Hongäddorna is significantly larger than hangäddorna. Pike has a good appetite and prefer prey fish in size correspond 10-15 % of the pike weight. In water with plentiful prey fish usually prefer the pike eating a large meal 1-2 times a week instead of chasing many small prey fish. This way of hunting characterize populations of larger fish while the smaller pike all the time is in a growth phase and therefore eat more often. Pike is also a cannibal and also eats much more than just fish, including frogs, water voles and chicks.

Pike hunt mainly by sight, but has also developed taste- and anosmia, confirmed when it is perfectly possible to catch pike with dead fish bait. The pike are most active during daylight hours, and studies have shown that the activity is almost non-existent in the dark.

The pike is a cold-water fish and therefore usually stays at the bottom, but it happens that it appears much higher up. It is very active especially during the time after spawning and autumn. These are also the periods when it is often in shallower water. During the summer, it seeks out deeper water, including deep edges and shoals. But in cold climates you can fish for big pike in shallow water all summer. The pike is active and eats in between 0,5 and 22 degrees and its optimum comfort temperature is at 12-14 degrees.


Walleye

Zander spawn from late March to early or mid-April. It requires the right temperature than the pike. Zander has a special way to hunt on, which is also the shape and body building reveals. The fish are not as coin as pike and can therefore not to swim fast. The eyes are large perch and its night vision is excellent. The zander is created to live on the ground where it can monitor the change over long distances. The zander is generally active in cloudy weather and at night.

In the summer pulls zander out to the lakes shallows and deep edges, but during the evening and night, it finds into shallower water, or higher up in the water, in both cases to hunt. Until the morning when it brightens, it finds its back out into deep water. These day hikes also occurs in the fall. Zander always prefer hard bottom such as rock, sand, rocks, foundations and edges. Especially smaller walleyes are sociable and often go in small schools, larger walleyes are usually loners. Gösen's is active and the food intake is greatest between 15 and 23 degrees. Gösens optimala trivseltemperatur, Located at +19 degrees.


Harr

The grayling spawn in the spring and thus differs from other Swedish salmonids that are all autumn- or winter spawning. Harr has wintered in rivers and lakes begin spawning migration during the thaw. Most adult grayling leave their overwintering sites, where they had been stationary over the winter, and seek appropriate parts of larger or smaller streams for the game. Sjölevande stocks playing mostly in the- and outlet to the lake. In Sweden playing grayling usually between April and June, at water temperatures between 4-12 ° C, the optimal lektemperaturen however, lies between 5-7 ° C. The game can last up to four weeks.

Initially eats harry glen zooplankton. They grow rapidly and reach 10 cm:'s length during the first summer. Young and adult grayling eat among others. bottendjur, insects from the water and fish. Grayling is stationary, often live in sparse estimation, but spreads already after the first summer. The fastest adult grayling reaches a length of about 40 cm på 4 years. For the slowest takes 10 years to reach 40 cm. The oldest grayling will be around 15-20 years. Maxvikt i Sverige ca 3 kg, graylings of about 1 kg is about seven years old.

In the southern part of the Swedish distribution area is relatively sparse populations to densify further north when the grayling thrive in running, oxygen-rich cold water. Besides coastal living populations (in områden with a salt lame below 5.5 ‰) are relatively general stream live trout in many of the larger and medium-sized rivers. The grayling occurs in Sweden very rarely in streams with an average width of less than 5 m. Far to the north, most of the sea-living populations of grayling in Sweden are also found.

A good fishing period directly after the game. July heat and high pressure often causes the water temperature rises in our streams, while the water flow decreases. Fish, especially the larger grayling, can be for long periods get fucked svårflörtad. In August dominated caddis which means that fishing continues to be best in the late afternoon and evening. August may also lead to low water flows and high water temperatures, which sometimes can make fishing difficult. September is a good trout month. Dry fly fishing on the calmer and selenium in lakes can provide gatherings.


Seatrout

The sea trout spawns in the autumn and the larvae reside 1-3 years in the watercourse, where the 16-22 cm long known as smolts in March-April migrating to the sea for the same year or the year after returning often to the same river. The utlekta fish migrating to the sea in the early spring. The sea reclaimed sea trout during the course of a few weeks his condition and it becomes shiny and oily. Until the fall of the sea trout migrate back into rivers.

The rise begins early in the major rivers but in the smaller sea trout begin to rise until the first autumn. The sea trout going up in waterways under cover of darkness and often choose dark and sheltered resting places. The sea trout do not eat in freshwater but if still would do it so it is not because of hunger. Uppvandringsfiskens stab like linked with the development of spawning, milt and roe. The shinier the fish are and the less developed rum and roes, the greater the chance that it will cut in freshwater. Colored fish hugger but not so happy, with the exception of heavy colored fish that can be aggressive when the time of the game approaching.

Seatrout increase is greatest in the context of rising water and high water and therefore tend to be the best fishing at high water. Nyuppstigen, blank trout still retains its chipper instinct after time in salt water and chop regularly in larger streams, while fishing in small streams are usually best during the evening, night and morning. There is also a big difference in sea trout's chopping behavior in different environments. The sea trout's optimal comfort temperature is between 4-9 degrees.


Salmon

In Swedish waters are simplified seen two different stocks of salmon: the actual Atlantic salmon and Baltic salmon. The latter is considered a avsnörd part of an original Atlantic live strain. A later avsnörning occurred in Vänern, where a third subgroup – “vänerlax”, or sometimes something wrong “Gullspång” – are. Each salmon watercourses also carries its own genotype, which the spontaneous basis let themselves be mixed only marginally with genetic material from other streams.

The salmon in the Baltic Sea Region is a separate genetic group derived from North Atlantic salmon. It is believed that the salmon spread up the rivers from the Ice Age glacial lakes early and later through the northernmost rivers connected with the Atlantic Ocean during the period Yoldia Sea. When the connection to the Atlantic later disappeared prevented Baltic salmon from migrating out. This isolation lasted for about two thousand years, now wanders Baltic salmon rarely out in the Kattegat, Skagerrak and the Atlantic. Of labeled lasxsmolt in the Baltic Sea region has only 0,04% re caught outside the Baltic. Perversely the main nursery areas in the ocean is in the entire Baltic Sea south of the Åland Islands, regardless of the river emigrating.

The salmon spawn in rivers and remains in 2-4 years, then migrate into the Baltic Sea for growth. This sea period lasts 1-4 year when it returns to play. Some salmon are almost exclusively males may return to the river after only one year in the ocean (sk grilse) and can return to play multiple times. Over 95 % of salmon returns to its home river, most propotion of felvandring occurs among grilsen. The salmon begin their migration from the Southern Baltic Sea in April-June against its rivers in North. What triggers this hike is probably water temperature and hours of sunshine per day, which increases after the winter. Studies show that walking salmon swimming rapidly towards its river. The hike avoids the salmon ruling central parts of the Baltic Sea and swims almost exclusively along the coast line until it reaches the area of ​​its hemflod. Most fish swim a distance of 25-45 km per day during the trek. Orientation to the home river is probably done through a so-called solar compass and olfactory memory. The main migration depth for the salmon is between 1 and 12 meter. The hiking deep in force for the day controlled most of the temperature and the fish swims anywhere in the range 7-10 degrees, representing salmon comfort temperature.

The salmon has similar features to the sea trout when it goes up into the rivers, the shinier the fish are and the less developed rum and roes, the greater the chance that it will cut in freshwater. Colored fish hugger but not so happy, with the exception of heavy colored fish that can be aggressive when the time of the game approaching.


Rainbow trout

Rainbow is no natural fish in Sweden, but it is grown and is in Swedish lakes for angling. It is a popular fish just because it is easily trapped and fighting well. It is also referred to as trout. Rainbow similar to brook trout in their body shape and gets its name because it has the sides a wide shiny red violet ribbon with black spots.

Rainbow eat various insects found in the lake as it is implanted in the firm also eat other fishes. The fished throughout the year but during the height of summer it is fairly immobile by themselves because of the warm water and pulls mostly down to the bottom, to cooler water. Rainbow comfort temperature is between 8-15 degrees.


Char

Like their relatives salmon and trout playing the char in the fall. In contrast to the other playing char on gravel- and stone bottoms at reefs and sandy banks, generally at 3-5 meters Djup i October-November. Char's larvae hatch in the spring and char is relatively stationary.

It is mainly through the paint as you can separate the char from their relatives salmon and trout. The abdominal color of a char in spawning changes from orange to deep red, the back is dark with shades of blue and green. Char exists naturally in Sweden that two closely related species, big trout and arctic char. The pages have stains in yellow and red and white fin edges are typical for all chars. Back- and anal fins have no white spots on large char unlike Arctic char. Charles got its name from the ancient Swedish rödhinger, which refers to the red abdomen.

Storröding, which is the major species, found in many lakes in southern Sweden as Vättern, Sums, Mycklaflon and verifier. It may be over 80 centimeters in length and weigh over 10 kilo. A large trout can be 25 years. During the warmer part of the year, staying big char majority of the time during the so-called thermocline, why then should concentrate fishing at depths between about 15-35 m. During the colder parts of the year, moving large char even in the higher water layers. Large char usually have fairly short, intensive stab periods and it is not certain that you selected the wrong bait or deep, without great char for now rests between chopping periods. These diets mostly applied pelagic. Younger individuals living mainly of insect larvae, crustaceans, snails and clams. Adult fish prefer vendace and smelt.

Arctic char which unlike trout forage in the lower water temperatures. Therefore, the catch in lakes that have both char and trout usually most trout in winter. It occurs in small streams that Arctic char also feed on their own species. Unlike trout it is more widespread that Arctic char moves in less shoals.
It thrives best in cold, clear water, for example in Lapland deep mountain lakes. Fish coloration depends on living area but, unlike the fish in the genus salmonids, it has a white part at the abdomen- and anal fin. Meanwhile there fjällröding games shifts the white abdomen in females color to red. The species has a special small scales. Adult animals are typically 40 to 85 centimeters long, And can weigh upwards 8,5 kilo. Regardless of the size is the average life expectancy at 40 years.
Arctic Char staying happily deep in the lake. It feeds by larval, insects, Mussels and Fries, For example minnow. Small mountain trout eat plankton. Regarding mating behavior are two variants. The first variant adds spawn on plants in the vicinity of the shoreline and games between September and January. The second variant adds spawn on the bottom 20 to 80 meters below the surface, and games in July and August.


Trout

Trout occur in a variety of environmental forms and in three different races marine, lake- and brook trout. The trout often differ in size and appearance. After the game, that in the northern hemisphere occurs from October to December, developing eggs and trout fry will be establishing territory, a property that follows them for life in flowing water. Trout have different activity periods primarily controlled by insect evolution of life. Brook trout have essentially their active periods during the morning and evening as well as a shorter period at midday.

Oringer feed on insects, larvae, worm and fish fry and usually with time also exhibit cannibalistic tendencies. In flowing water, the diet to 90 % of insects that operates in the power and 10 % comprises ytinsekter. The trout hunts by sight, but several studies have shown that even lateral line organ used.

Trout's position places consist of such places where it can consume as little energy as possible to maintain itself in power, but where there are also plenty of food, that is, the power edges, riparian and burrows. Brook trout often choose shady position places.

The trout also live in lakes, from the smallest to the largest. In less sjöar kryssar fish around, frequent i strandzonen. Here it lives mainly on insects, crustaceans, larvae, worms and fish fry. Above all vegetated areas, uddar, tongues of land and basic platform attracts fish, Likewise, the outlet streams from secure sites. During the summer, pulling the fish into deeper water but it often comes in to land the morning and evening. While brook trout in streams can be difficult to catch fish in lakes are more willing to bite.  Degradation comfort temperature is between 6-16 degrees.
