Genetic stock identification reveals greater use of an oceanic feeding ground around the Faroe Islands by multi-sea winter Atlantic salmon, with variation in use across reporting groups
O'Sullivan, Ronan James; Ozerov, Mikhail; Bolstad, Geir Hysing; Gilbey, John; Jacobsen, Jan Arge; Erkinaro, Jaakko; Rikardsen, Audun H.; Hindar, Kjetil; Aykanat, Tutku (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-18)While it is known that the oceans around the Faroe Islands support an Atlantic salmon (Salmo salar) feeding ground, the relative use of this resource by different age classes and populations remains largely unexplored. Using genetic stock identification and run–reconstruction modelling, we observed a consistent pattern whereby the proportion of multi-sea winter salmon (MSW—fish that have spent ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-16)1. Animals employ various foraging strategies along their ontogeny to acquire energy, and with varying degree of efficiencies, to support growth, maturation and subsequent reproduction events. Individuals that can efficiently acquire energy early are more likely to mature at an earlier age, as a result of faster energy gain which can fuel maturation and reproduction.<p><p> 2. We aimed to test the ...
