Marine depth use of sea trout Salmo trutta in fjord areas of Central Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-15)
The vertical behaviour of 44 veteran sea trout <i>Salmo trutta</i> (275–580 mm) in different marine fjord habitats (estuary, pelagic, near shore with and without steep cliffs) was documented during May–February by acoustic telemetry. The swimming depth of <i>S. trutta</i> was influenced by habitat, time of day (day v. night), season, seawater temperature and the body length at the time of tagging. ...
Ocean predation and mortality of adult Atlantic salmon
(Journal article; Peer reviewed, 2019-05-27)
Predation and mortality are often difficult to estimate in the ocean, which hampers the management and conservation of marine fishes. We used data from pop-up satellite archival tags to investigate the ocean predation and mortality of adult Atlantic salmon (Salmo salar) released from 12 rivers flowing into the North Atlantic Ocean. Data from 156 tagged fish revealed 22 definite predation events (14%) ...
