Fysiska strukturer i Umeälvens gamla älvfåra och dess inverkan på laxsmoltens utvandringsframgång

The survival of hatchery reared smolts is generally low after release. To get a better understanding of what variables affecting migration success, Atlantic salmon smolts were studied during their out-migration in the old river channel in the lower part of river Umeälven. The area consists of shifting habitat and complex structures which causes difficulties for smolt on their migration out to sea. The aim of this study was to try to determine the effects of feed restriction, fin conditions and different physical barriers in the river, on the migratory behavior of Atlantic salmon smolts in the river Umeälven. The river was divided into six different sections using acoustic receivers strategically deployed along the river. Two-year old hatchery-reared smolts (n=150), in three different weight classes, were tagged with acoustic transmitters.

Migration : Dokumenthanteringssystem till Webbapplikation

Migration mellan system används oftast när ett system har blivit föråldrat och då det märks att det inte längre är lika effektivt gentemot nyfunnen teknik. Då är det därför intressant att använda sig av migration, när det är av intresse att skapa ett nyare system utifrån det gamla. Detta arbete går igenom och löser problem vilka uppstått när en migration mellan ett dokumenthanteringssystem till en webbapplikation görs. Men fokuseringen har riktats mot att hitta den bästa migrations och övergångsmetoden för att kunna skapa en bra, enkel och effektiv migration mellan ett dokumenthanteringssystem till en webbapplikation.

Full Circle: upstream and downstream migration of Atlantic salmon (Salmo salar) in the northern Swedish river Vindelälven

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

Aktivering av trafiksäkerhetskameror : En studie av kameraaktiveringens effekter på fordonshastigheter i Sverige

During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.

Perspektiv p? migrationspolitik: aktivisters syn p? den polska statens hantering av migrationskrisen vid gr?nsen mot Belarus under 2021?2024

Poland has since 2021 dealt with the migration crisis at its border with Belarus and when the new government took power in 2023, many had high hopes for its management of the crisis. But the government has opposed the EU's migration policy and continues the strict migration policies of the last government, which earlier studies have theorized, if it?s sign of a securitization of EU?s own migration policies. This essay examines the experiences of activists who work at the border, by performing interviews and a thematic analysis regarding the Polish state?s handling of the migration crisis with the change of government in 2023 and how they see that it has affected Poland and EU?s relationship.

Mellan säkerhet och mänskliga rättigheter : en studie av den svenska officiella migrationsdiskursen

This paper focuses on the Swedish migration discourse and investigates if and to what extent it is dominated by a security perspective. Analysing a number of official texts and documents I want to show how the discourse describes migrants and what implications this carries with it for the migrants and for the Swedish migration politics. Through discourse analysis I have analysed whose security that is prioritised, the Swedish or the refugees, who is the refugee and the asylum seeker, and who is the illegal migrant in the Swedish official migration discourse. As a theoretical frame for the analysis I have used theories on migration and security. These include theories on the securitisation of politics, the globalisation and the creation of political identity from the nation state perspective and theories on the connection between migration and security.My results show that a security discourse is dominating the Swedish official migration discourse and is therefore defining our reality and the identities of refugees, asylum seekers and illegal migrants.

Hur påverkar ålder och fetthalt laxsmoltens utvandring till havet?

AbstractPrevious studies have shown that wild smolt have 2.5-4.5 times higher survival rate than smolt grown in culture and that starved reared smolt behave more like wild born smolt. The purpose of this project was to study whether there are differences in migration patterns and survival during migration to the coast between wild and reared smolt and between different types of reared smolt.In 2009, 25 smolts in three different groups were tagged with acoustic transmitters: Wild Born, conventionally reared 2-year and 1 ?year old smolt. For the 2010 trial there was also added a group of reared 2 ?year old smolt that were starved before release.

?H?LLBAR MIGRATION?? En kritisk diskursanalys av Europeiska unionens reglering av asylansvar

This bachelor?s thesis aims to examine how the ?New Pact on Migration and Asylum? construct the discourse on ?sustainable migration? and ?efficiency? in the European Union. The new jurisprudence concerning migration and asylum in the European Union seeks to establish a more ?fair, efficient and sustainable migration and asylum system?. To analyze the discourses, a critical discourse analysis is applied to the former asylum regulation, Dublin regulation III, a revised and withdrawn proposal, Dublin regulation IV, and future legislation.

Att byta land - hur migrationserfarenheter kan påverka individen

Syftet med denna uppsats har varit att lyfta fram några personers egna erfarenheter av migration för att diskutera vad migration kan innebära för dessa människor och hur de upplever att dessa erfarenheter har påverkat dem. Genom att intervjua personer som själva har migrerat har vi kunnat ta reda på hur dessa personer definierar följderna av migrationen och hur de upplever att de har förändrats och vilka resurser och tillgångar de har förskansat sig till följd av migrationen. Resultaten pekar mot att migration trots svåra upplevelser och processer kan leda till en positiv utveckling för migranten som person. Vi har förstått detta resultat utifrån ett lösningsfokuserat perspektiv och utvecklat en tanke om hur socialt arbete med migranter eventuellt kan förbättras med fokus på de positiva aspekterna av migration och dess konsekvenser..

En påstådd sexualitet - En diskursanalytisk undersökning av svenska migrationsmyndigheters syn på sexualitet i relation till hbtq-personers asylärenden

The purpose of the essay is to examine the views on sexuality that guide the Swedish Migration board and court?s judgments and decisions in asylum cases. The essay investigates seven cases from the Swedish Migration court regarding asylum seekers from seven different countries seeking protection in Sweden due to their sexuality and/or gender identity. By applying discourse analysis, along with the theoretical perspectives of Judith Butler and the postcolonial critique of Chandra Talpade Mohanty, the essay discuss what kind of criteria and/or practice is demanded of the asylum seekers to be rendered as trustworthy. The essay concludes that the asylum seekers are considered untrustworthy by the migration authorities when not acting according to a (hetero)normative sexuality.

Jämlika villkor? En diskursanalys av LOs presentation av arbetskraftsinvandring under åren 2000-2006

Central labour market actors have come to an agreement ? Sweden is going to need labour migration. In spite of the agreement the actors disagree upon how the labour migration should be designed. This essay examines how the union organisation, LO presents labour migration in their rapports during the years 2000-2006. This is done through Laclau and Mouffes discourse theory and a merge with postcolonial theory.
