Trophic niche similarity among sea trout Salmo trutta in Central Norway investigated using different time-integrated trophic tracers
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-21)
From 2011 to 2013, anadromous brown trout Salmo trutta (213−730 mm, total body length, LT) were collected during or shortly after their marine feeding migration at 7 different localities in central Norway. The mean volume of stomach content (%) of marine fish prey eaten by S. trutta captured in marine waters varied from 34 to 89%. There was a high prevalence (67−100%) for parasite groups potentially ...
Marine trophic niche-use and life history diversity among Arctic charr Salvelinus alpinus in southwestern Greenland
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-22)
Life history strategies and potential marine niche use of Arctic charr <i>Salvelinus alpinus</i> (<i>n</i> = 237, 84–652 mm, total body length, <i>L<sub>T</sub></i>) were determined during the ice‐free season (2012) at three different watercourses in south‐western Greenland. All Arctic charr were collected from freshwater habitats. Based on stable isotopes of δ<sup>34</sup>S, the Arctic charr were ...
