Vertical movements of Atlantic salmon postsmolts relative to measures of salinity and water temperature during the first phase of the marine migration
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
The migratory behaviour of hatchery-reared Atlantic salmon, Salmo salar L., post-smolts during the
first phase of the marine migration was examined to assess their susceptibility to salmon lice, Lepeophtheirus
salmonis (Krøyer), infestations. Swimming depths of eight post-smolts relative to the measured salinity and
temperature were monitored for an average of 11.4 h following release outside the ...
Migratory behaviour and survival rates of wild northern Atlantic salmon (Salmo salar) post-smolts: effects of environmental factors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-12-03)
To study smolt behaviour and survival of a northern Atlantic salmon (Salmo salar) population during river descent, sea entry and fjord migration, 120 wild S. salar were
tagged with acoustic tags and registered at four automatic listening station arrays in the mouth of the North Norwegian River Alta and throughout the Alta Fjord. An estimated 75% of the post-smolts survived from the river mouth, ...
