  1. 1. Effects of global warming on Eurasian perch (Perca fluviatilis) in the Baltic Sea : does the growth response to increased temperatures differ along a latitudinal gradient?

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Mattias Grunander; [2018]
    Nyckelord :body-length at age; growth; size dependent growth; Perca fluviatilis; climate change; temperature; Baltic Sea; latitude;

    Sammanfattning : Anthropogenically caused climate change, i.e. global warming, is anticipated to affect all living organisms. Particularly ectotherms are predicted to show strong responses to the increased warming, as their body temperature closely tracks ambient temperatures and because body temperature profoundly affects many physiological functions e.

  3. 2. Life history trade-offs in Anadromous Burbot Lota lota (Linnaeus 1758) from Rickleån and Sävarån, Northern Sweden

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Mikael Sandberg; [2015]
    Nyckelord :life history trade-offs; anadromous burbots; Bothnian Bay; Rickleån; Sävarån; otoliths;

    Sammanfattning : Anadromous burbots Lota lota (Linnaeus 1758) from two similar rivers in the Gulf of Bothnia area, Sävarån and Rickleån, Northern Sweden, were compared. The aim was to test for and explain differences in ecology. Spawning burbots in Sävarån were smaller, younger, grew slower and were more densely populated. LÄS MER

  4. 3. SIZE DEPENDENT FECUNDITY IN THE SIGNAL CRAYFISH AND ITS IMPORTANCE FOR A SUSTAINABLE FISHERY

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Johan Martinsson; [2011]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : The signal crayfish (Pacifastacus leniusculus) is of great economic and social value in Sweden. Therefore it is of great importance that knowledge and experience is obtained and applied when creating a sustainable fishing industry. LÄS MER
