    Can collective memories shape fish distributions? A test, linking space-time occurrence models and population demographics 
    Macdonald, Jed; Logemann, Kai; Krainski, Elias T.; Sigurðsson, Þorsteinn; Beale, Colin M.; Huse, Geir; Hjøllo, Solfrid S.; Marteinsdottir, Gudrun (Wiley, 2017-09-13)
    Social learning can be fundamental to cohesive group living, and schooling fishes have proven ideal test subjects for recent work in this field. For many species, both demographic factors, and inter‐ (and intra‐) generational information exchange are ...

    Issues and Importance of Age and Length Data in Fisheries Models 
    Frater, Paul (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-06)
    Age and length (i.e. composition) data are, along with abundance indices, some of the most basic yet informative data collected in fisheries science. Measurements on age and length have been collected since the study of fish and fish stocks began in ...

    A millennium of north-east Atlantic cod juvenile growth trajectories inferred from archaeological otoliths 
    Ólafsdóttir, Guðbjörg Ásta; Pétursdóttir, Gróa; Bardarson, Hlynur; Edvardsson, Ragnar (Public Library of Science (PLoS), 2017-10-27)
    Archaeological excavations of historical fishing sites across the North Atlantic have recovered high quantities of Atlantic cod (Gadus morhua) bones. In the current study we use Atlantic cod otoliths from archaeological excavations of a historical ...

    Ocean predation and mortality of adult Atlantic salmon 
    Strøm, John Fredrik; Rikardsen, Audun Håvard; Campana, Steven; Righton, David; Carr, Jonathan; Aarestrup, Kim; Stokesbury, Michael J. W.; Gargan, Patrick; Javierre, Pablo Caballero; Thorstad, Eva Bonsak (Springer Science and Business Media LLC, 2019-05-27)
    Predation and mortality are often difcult to estimate in the ocean, which hampers the management and conservation of marine fshes. We used data from pop-up satellite archival tags to investigate the ocean predation and mortality of adult Atlantic ...

    Population dynamics of fish juveniles and invertebrates in Icelandic waters 
    Jonasson, Jonas Pall (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-01)
    The marine ecosystem around Iceland is shaped by its position in one of the most hydrographically complicated regions of the North Atlantic. The response of marine populations to those diverse conditions is expected to be different across taxonomically ...

    Temperature selectivity in Icelandic and Northeast-Arctic cod 
    von Leesen, Gotje (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-06)
    Increasing water temperatures are predicted worldwide, with high amplitudes in the Arctic and sub-Arctic regions exceeding predictions for other regions. An understanding how Atlantic cod (<i>Gadus morhua<i>) reacted to changing environmental conditions ...
