  1. 1. Tillväxt av öring (Salmo trutta) i bastuån : Täthets- och temperaturberoende?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Fredrik Curman; [2024]
    Nyckelord :;

    Sammanfattning : Performance of stream living juvenile brown trout (Salmo trutta) may be affected by both intra- and intercohort competition. In this study I examined if growth and density of cohorts of young-of the-year (0+) trout are dependent on temperature and density of older (>0+) trout and 0+ trout. LÄS MER

  3. 2. MODELLING THE SMOLT PRODUCTIVITY OF BROWN TROUT (SALMO TRUTTA) IN HAGA Å

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Lukas Almgren; [2023-10-30]
    Nyckelord :Brown trout; Salmo trutta; Trout habitat score; THS; Haga å; electro-fishing survey;

    Sammanfattning : The brown trout (Salmo trutta) is a facultatively anadromous species, some individuals migrate from the rearing environment in the rivers to the sea while other individuals stay in fresh water. To determine the suitability of a stream for juvenile trout the organization SGBALANST has developed what is called the "Trout habitat score" (THS) model. LÄS MER

  4. 3. Web Interface for Systems Engineering DesignTools – A web application for facilitating the collaboration between business- and engineering teams

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Erik Berg; Oscar Hedenäs Bennet; William Hugo; Albin Karlsson Landgren; Isak Magnusson; David Salmo; [2023-03-03]
    Nyckelord :Value driven design; BPMN; Discrete event simulation; Web interface; System engineering design; ISO 15288; Python; React;

    Sammanfattning : The interest in improving and optimising project planning and execution is currently large. The Value-Driven Design methodology of Systems Engineering aims to help with this through a focus on measuring value from early stages of projects. LÄS MER

  5. 4. Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Jonna Hellesten; [2023-01-26]
    Nyckelord :;

    Sammanfattning : Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological changes to prepare for SW transfer, the transfer result in a mortality rate of around 13-19%, and significant appetite- and growth reductions.

  7. 5. FRÅN UTSÄTTNING AV ÖRINGROM TILL ÅRSYNGEL : EFFEKTER AV UTSÄTTNINGSMETODIK OCH INTRASPECIFIKA INTERAKTIONER

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :David Rode; [2023]
    Nyckelord :;

    Sammanfattning : Egg stocking is a common method of re-establishing brown trout (Salmo trutta) populations, while the outcomes have been shown to give different results depending on variations in methods and locations. More recently, the dispersal of yearlings has been studied, but research on intraspecific interactions after egg stocking and the optimal number of eggs stocked are less studied. LÄS MER
