26. February 2023 The diet of nearly six hundred salmon post-smolt caught in Norwegian fjords was analysed in a new study. Already at that early stage of the marine migration, it is important for the salmon to find fish larvae to feed on.
26. February 2023 New study of iteroparity, or repeat spawning, of Atlantic salmon in 179 rivers shows that the proportion of repeat spawners averaged 3.8% (0-26% across rivers). Females were more often repeat spawners than males and lost less body mass between each spawning.
26. February 2023 Invasive pink salmon eat what they find; fish larvae, amphipods, krill, like Atlantic salmon, but so far abundance is too low to expect competition in the ocean. Local impacts by pink salmon on coastal ecosystems cannot be ruled out.
26. October 2022 River Eira once harbored some of the largest salmon in the world, but has now evolved into an ordinary salmon population. New study shows clear evidence of an unintentional human-induced evolution.
25. October 2022 While it is known that the oceans around the Faroe Islands support an Atlantic salmon feeding ground, the relative use of this resource by different age classes and populations has, until now, been largely unexplored.
7. June 2022 New study of adult Atlantic salmon in near-coastal areas shows that they migrate through surface waters and perform aperiodic dives - both on outward migration and return.
20. April 2022 Increased zooplankton biomass was positive for marine growth, and salmon lice negative. Data from the River Etne fish trap are published in a new study by Alison Harvey, Øystein Skaala and colleagues
4. April 2022 New study of stomach content data over a 25-year period shows how important fish larvae are for the marine diet of young Atlantic salmon - and how feeding conditions are impacted by ocean current systems and inflow of Arctic water.
5. March 2022 During just one year, the growth of wild salmon was greatly reduced along large parts of the Norwegian coast, particularly among populations in Western Norway and Southern Norway. Scientists have uncovered why this happened in a new study - and at the same time revealed an ecological regime shift in the Northeast Atlantic Ocean.
24. February 2022 Congratulations to Yann Czorlich and co-authors with publishing important results on Atlantic salmon in prestigious Science!
19. September 2021 During the last few decades, many wild Atlantic salmon populations have declined. One possible contributing factor for the decline is reduced prey availability at sea.
13. September 2021 Extensive international collaboration and analysing 30 year’s catches of salmon at sea provide new information on key foraging areas.
30. June 2021 The global scale of climate change, altered ocean ecosystems and reduced sea survival make these threats to Atlantic salmon diffi
13. June 2021 Many surprises from tagging Atlantic salmon with pop-up satellite tags. Further north and east than we thought, more use of oceanic fronts, deeper dives and staying in colder water.
26. January 2021 We looked at potential competition between salmon and mackerel or herring, in a new publication. There was no evidence to support the hypothesis that lower marine survival for salmon in recent years can be explained by competition with
