A model for Arctic Charr populations in Cambridge Bay considering fluctuating environment
… population model to describe the behaviour of an Arctic Charr population. Given the properties of the model, a weak ergodic behaviour is expected in the long run. Then, utilizing data collected in Cambridge Bay and using a generalized weighted least squares method, model parameters are estimated. …

Effect of population density on diel activity and growth in stream-dwelling Arctic charr Salvelinus alpinus
… limited attention. I used juvenile (age 1+) Arctic charr Salvelinus alpinus as a model species to test the prediction that individuals at high population density will increase their activity rate and distribute their feeding activity over a greater portion of the 24 h cycle. …

Population ecology of landlocked Arctic charr, <i>Salvelinus alpinus L</i>., in the Canadian High Arctic
… activities. Four landlocked populations of Arctic charr, <i>Salvelinus alpinus</i> L., were surveyed at 81 oN, close to the northerly extreme of the species range. They were single-species populations consisting of two distinct size modes, "Dwarf" and "Normal" charr, but with major …

Trophic polymorphism in the Arctic charr (Salvelinnus alpinus (L.)) of Lochs Rannoch, Ericht and Tay, Scotland
Morphometric analysis of Loch Rannoch charr indicated that in addition to the pelagic morph previously described, the benthic morph previously described consists of two distinct morphs. Thus one form had a relatively small head, short gill rakers and consumed only benthic invertebrates, whilst the …

Effects of environmental enrichment on personality traits in juvenile Arctic charr (Salvelinus alpinus) : interplay with brain morphology, growth performance and implication for welfare
Arctic charr (Salvelinus alpinus) is the northernmost distributed freshwater fish and considered to be the most cold-adapted salmonid. In overall, Iceland is graded as the largest worldwide producer and its system considered as sustainable farmed system. Despite that, no study has yet targeted the …

Biological diversity of epibenthic invertebrates in relation to environmental factors in lava caves around Lake Mývatn (N-E Iceland)
… lava bedrock, creating small ponds inhabited by Arctic charr and diverse invertebrates. The unique geomorphology of the caves creates various habitats, and along with that the potential for different invertebrate communities. In summer 2014, I sampled epibenthic crustaceans in 18 caves …

Aspects of the conservation biology of Coregonus lavaretus in Britain
… plastic species that vary between sites such as Arctic charr (Salvelinus alpinus) and brown trout.

Ante- and post-mortem factors affect muscle protein functionality from fish
… Administration.;For ante-mortem handling stress, Arctic charr, Salvelinus alpinus, hatched at 6.5 and 9.5°C and categorized as large, medium, and small when 6-m old, were assigned to four handling stress treatments: (1) processing with no stress; (2) processing immediately after stress; (3) …
