    • Circumpolar patterns of Arctic freshwater fish biodiversity: A baseline for monitoring 

      Laske, Sarah M.; Amundsen, Per-Arne; Christoffersen, Kirsten Seestern; Erkinaro, Jaakko; Guðbergsson, Guðni; Hayden, Brian; Heino, Jani; Holmgren, Kerstin; Kahilainen, Kimmo Kalevi; Lento, Jennifer; Orell, Panu; Östergren, Jan; Power, Michael; Rafikov, Ruslan; Romakkaniemi, Atso; Svenning, Martin; Swanson, Heidi; Whitman, Matthew; Zimmerman, Christian E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-01)
      Climate change, biological invasions, and anthropogenic disturbance pose a threat to the biodiversity and function of Arctic freshwater ecosystems. Understanding potential changes in fish species distribution and richness is necessary, given the great importance of fish to the function of freshwater ecosystems and as a resource to humans. However, information gaps limit large‐scale studies and our ...

    • The effect of temperature and dietary energy content on female maturation and egg nutritional content in Atlantic salmon 

      Maamela, Katja S.; Åsheim, Eirik Ryvoll; Debes, Paul V.; House, Andrew H.; Erkinaro, Jaakko; Liljeström, Petra; Primmer, Craig R.; Mobley, Kenyon (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-17)
      The environment experienced by a female influences reproductive traits in many species of fish. Environmental factors such as temperature and diet are not only important mediators of female maturation and reproduction but also of egg traits and offspring fitness through maternal provisioning. In this study, we use 3-year-old tank-reared Atlantic salmon from two Finnish populations to investigate the ...

    • Genetic stock identification reveals greater use of an oceanic feeding ground around the Faroe Islands by multi-sea winter Atlantic salmon, with variation in use across reporting groups 

      O'Sullivan, Ronan James; Ozerov, Mikhail; Bolstad, Geir Hysing; Gilbey, John; Jacobsen, Jan Arge; Erkinaro, Jaakko; Rikardsen, Audun H.; Hindar, Kjetil; Aykanat, Tutku (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-18)
      While it is known that the oceans around the Faroe Islands support an Atlantic salmon (Salmo salar) feeding ground, the relative use of this resource by different age classes and populations remains largely unexplored. Using genetic stock identification and run–reconstruction modelling, we observed a consistent pattern whereby the proportion of multi-sea winter salmon (MSW—fish that have spent ...

    • Temporally stable population-specific differences in run timing of one-sea-winter Atlantic salmon returning to a large river system 

      Vähä, Juha-Pekka; Erkinaro, Jaakko; Niemelä, Eero; Primmer, Craig R.; Saloniemi, Irma; Johansen, Morten; Svenning, Martin; Brørs, Sturla (Journal article; Tidsskriftartikkel; Peer reviewed, 2010-12-06)
      The understanding of migration patterns can significantly contribute to conservation and management. The spawning migrations of Atlantic salmon (<i>Salmo salar</i>) cover thousands of kilometers from the feeding areas at sea to their natal rivers to reproduce. Migrating salmon are exposed to intensive harvest, but little is known of the population‐specific differences in migration behavior. In this ...
