Atlantic salmon is a well-studied species, but there are still mysteries of where they reside in the ocean and what impacts their marine survival. ATLANTIC SALMON AT SEA - factors affecting their growth and survival (SeaSalar) is a research program where research institutions join forces to increase the knowledge on Norwegian salmon at sea.

Results in this study suggest that 23-mm long PIT tags can be used to tag fish down to 13 cm total length, and 12-mm long PIT tags can be used to tag fish down to 7 cm total length

Reliable survival estimates based on tagged fish depend on using small enough tags

PIT-tags are often used to study marine mortality in salmon. It is important that the tagging itself does not increase mortality. New review publication assessed tagging effects based on available studies.

Master thesis with exciting results on marine feeding of young salmon

Lea Hellenbrecht successfully defended her master thesis at the University of Bergen in the beginning of September, on feeding of wild Atlantic salmon post-smolts in Norwegian fjords.

New collaboration expands the SeaSalar team

Lo Persson has joined us as a postdoc funded by the Swedish Research Council. - A welcome Swedish-Norwegian collaboration that will strengthen the knowledge exchange between the Atlantic and Baltic, and enable new studies on how growth and genes impact age at maturity in salmon.
