  7. 5. Population regulatory processes in the Baltic salmon (Salmo salar)

    Author : Stefan Skoglund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Knowledge and understanding of population regulation is the foundation that allows for sustainable harvest of natural populations. In this thesis, I explore potential sources of bias in stock recruitment relationships resulting from potential spawning behaviours, and investigate alternative methods that can be used in order to evaluate population regulatory processes and improve estimates of stock-assessments of the Atlantic salmon (Salmo salar) in the Baltic Sea.
