Fyris
Fyrisån (, "the Fyris river") is a river in the Swedish province of Uppland, which passes through the city of Uppsala and ends in Lake Mälaren. The "Sala" river in Uppland was changed in the 17th century in memory of the Fyrisvellir battle, mentioned in the Icelandic sagas, as it was the belief that the marshy plains called "Föret" was the site of the famous Battle of Fýrisvellir in the late 10th century. Boats can sail up the river from Lake Mälaren all the way to central Uppsala where two weirs make further progress impossible. In the summer of 2007 the construction of a fish ladder was started, in order to make it possible for the asp, an endangered and potamodromous fish, to pass the weirs and reach its spawning Spawn is the eggs and sperm released or deposited into water by aquatic animals.

Uppsala
Uppsala (, or all ending in , ; archaically spelled ''Upsala'') is the county seat of Uppsala County and the fourth-largest city in Sweden, after Stockholm, Gothenburg, and Malmö. It had 177,074 inhabitants in 2019. Located north of the capital Stockholm it is also the seat of Uppsala Municipality. Since 1164, Uppsala has been the ecclesiastical centre of Sweden, being the seat of the Archbishop of the Church of Sweden. Uppsala is home to Scandinavia's largest cathedral – Uppsala Cathedral, which was the frequent site of the coronation of the Swedish monarch until the late 19th century. Uppsala Castle, built by King Gustav Vasa, served as one of the royal residences of the Swedish monarchs, and was expanded several times over its history, making Uppsala the secondary capital of Sweden during its greatest extent. Today it serves as the residence of the Governor of Uppsala County. Founded in 1477, Uppsala University is the oldest centre of higher education in Sca ...

Fyrisvellir
Fyrisvellir, Fyris Wolds or Fyrisvallarna was the marshy plain (''vellir'') south of Gamla Uppsala where travellers had to leave the ships on the river Fyris (Fyrisån) and walk to the Temple at Uppsala and the hall of the Swedish king. The name is related to, or derived from, Old Norse ''Fyrva'' which meant "to ebb" and it referred to the partially inundated soggy plains that today are dry farmland and the modern town of Uppsala. In mediaeval times, a royal estate called ''Førisæng'', "Fyris meadow", was located near this field. The small lakes ''Övre Föret'', "the Upper Fyri", and ''Nedre Föret'', "the Lower Fyri", are remains of this marsh and retain a modern form of ''Fyri'' (the -''t'' suffix is the definite article, which lake names always take in Swedish). The field went alongside what was renamed the ''Fyris river'' (Fyrisån) in the 17th century to make the connection between the river and the Sagas more obvious. Thunberg, Carl L. (2012).

Battle Of Fýrisvellir
The Battle of Fýrisvellir was fought in the 980s on the plain called Fýrisvellir, where modern Uppsala is situated, between King Eric the Victorious and an invading force. According to Norse sagas, this force was led by his nephew Styrbjörn the Strong. Eric won the battle, and became known as "the Victorious". It is mentioned by Saxo Grammaticus in ''Gesta Danorum'' and in a number of medieval Icelandic sources, including '' Eyrbyggja saga'', ''Knýtlinga saga'', and '' Hervarar saga''. An account is found in the Old Norse translation of Oddr Snorrason's lost Latin life of the Norwegian king Olaf Tryggvason, known as ''Odds saga munks'', and a more detailed account in the short story ''Styrbjarnar þáttr Svíakappa'', which is included in the saga of the Norwegian king Olaf II in ''Flateyjarbók''; this version includes skaldic verses including two '' lausavísur'' by Þórvaldr Hjaltason.

Walpurgis Night
Walpurgis Night (), an abbreviation of Saint Walpurgis Night (from the German ), also known as Saint Walpurga's Eve (alternatively spelled Saint Walburga's Eve), is the eve of the Christian feast day of Saint Walpurga, an 8th-century abbess in Francia, and is celebrated on the night of 30 April and the day of 1 May. This feast commemorates the canonization of Saint Walpurga and the movement of her relics to Eichstätt, both of which occurred on 1 May 870. Saint Walpurga was hailed by the Christians of Germany for battling "pest, rabies, and whooping cough, as well as against witchcraft". Christians prayed to God through the intercession of Saint Walpurga in order to protect themselves from witchcraft, as Saint Walpurga was successful in converting the local populace to Christianity. In parts of Europe, people continue to light bonfires on Saint Walpurga's Eve in order to ward off evil spirits and witches. Others have historically made Christian pilgrimages to Saint ...

Nationalencyklopedin
''Nationalencyklopedin'' (; "The National Encyclopedia" in English), abbreviated NE, is a comprehensive contemporary Swedish-language encyclopedia, initiated by a favourable loan from the Government of Sweden of 17 million Swedish kronor in 1980, which was repaid by December 1990. The printed version consists of 20 volumes with 172,000 articles; the Internet version comprises 260,000 articles (as of June 2005). History The project was born in 1980, when a government committee suggested that negotiations be initiated with various publishers. This stage was finished in August 1985, when in Höganäs became the publisher responsible for the project. The project specifications were for a modern reference work based on a scientific paradigm incorporating gender and environmental issues. Pre-orders for the work were unprecedented; before the first volume was published in December 1989, 54,000 customers had ordered the encyclopedia. The last volume came out in 1996, with three s ...

Fish Ladder
A fish ladder, also known as a fishway, fish pass, fish steps, or fish cannon is a structure on or around artificial and natural barriers (such as dams, locks and waterfalls) to facilitate diadromous fishes' natural migration as well as movements of potamodromous species. Most fishways enable fish to pass around the barriers by swimming and leaping up a series of relatively low steps (hence the term ''ladder'') into the waters on the other side. The velocity of water falling over the steps has to be great enough to attract the fish to the ladder, but it cannot be so great that it washes fish back downstream or exhausts them to the point of inability to continue their journey upriver. History Written reports of rough fishways date to 17th-century France, where bundles of branches were used to make steps in steep channels to bypass obstructions. A pool and weir salmon ladder was built around 1830 by James Smith, a Scottish engineer on the River Teith, near Deanston, Perths ...

Spawn (biology)
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa ( milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mosquitoes and corals, which are actually sma ...

Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements m ...

Asp (fish)
The asp (''Leuciscus aspius'') is a European freshwater fish of the Cyprinidae family. It is sometimes considered by taxonomic authorities to be one of two members of the genus '' Aspius''. It is protected under Appendix III of the Bern Convention and listed as least concern on the IUCN Red List. Normally, asps are between in length, with some reaching , and weighing up to . They inhabit lakes and lower reaches of rivers and estuaries. In April to June, asps migrate from lakes to streams for spawning. Spawning is triggered by the rise in temperature and usually starts at . The eggs attach to rocks, gravel, and water plants. After around two weeks, they hatch and the fry drift downstream to calmer waters. They tend to be active during the evening, when they may create large splashes as they hunt near the surface of the water. Asps can be found in Estonia, Lithuania, Latvia, Germany, Norway, Sweden, Finland, the Czech Republic, Poland, Ukraine, Bulgaria, Romania, Russia, Switze ...

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water beh ...
