    Sammanfattning : Kattegat is an area between Denmark and Sweden that connects the Atlantic Ocean to the Baltic Sea. It has long been an important source for fishery of cod (Gadus morhua). LÄS MER

  4. 3. Can body size parameters be used to distinguish the Kattegat cod (Gadus morhua) stock from the North Sea cod stock?

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Viktor Hedlund; [2017]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Atlantic cod is one of the world´s most important commercial fish stocks and is dependent on fishing regulations for its wellbeing and survival. An important part in fisheries management is information of the stock distribution. This is needed to not cause overestimations that results in heavy overfishing. LÄS MER

  5. 4. Tankar kring Torsk : Isotopanalyser av torskkotor för att undersöka vikten av torskimport i medeltida Sverige

    Kandidat-uppsats, Stockholms universitet/Arkeologiska forskningslaboratoriet

    Författare :Beatrice Krooks; [2013]
    Nyckelord :Torsk; isotop; isotopanalys; medeltid;

    Sammanfattning : This essay discusses the import of cod (Gadus morhua) in Sweden during the Middle Ages through isotope analysis of cod vertebrae. The isotope analysis is used to trace the cods origin to either the Baltic Sea or the Atlantic Ocean. The bones were subjected to d13C, d15N and d34S analysis; 64 of  the analyzed bones met the quality criteria. LÄS MER
