  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. The deductibles impact on the risk premium

    Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Ludvig Bergman; [2023]
    Nyckelord :deductible; insurance mathematics; non-life insurance pricing; Försäkringsmatematik; självrisk; självrisker;

    Sammanfattning : The aim of this master thesis is to derive methods that assesses the impact the deductiblehas on the risk premium of an insurance contract. The additive structure of a deductiblenecessitates approaches beyond treating it as a regular covariate in a generalized linearmodel for predicting the risk premium. LÄS MER

  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
