Fecundity and water flow influence the dynamics of Atlantic salmon
(Journal article; Peer reviewed, 2016)Populations are retained at reduced levels by resource competition and environmental stochasticity. In the Norwegian River Imsa, the relationship between fecundity of Atlantic salmon (Salmo salar) spawners and number of ... -
Influence of gear switching on recapture of Atlantic salmon (Salmo salar) in catch-and- release fisheries
(Journal article; Peer reviewed, 2016)Anglers that release Atlantic salmon (Salmo salar) in recreational fisheries do so with the intention that the fish will survive and contribute to succeeding generations. In some instances, salmon that are released may be ... -
Otolith microchemistry combined with genetics reveal patterns of straying and population connectivity in anadromous brown trout (Salmo trutta)
(Peer reviewed; Journal article, 2023)Salmonids are well known for their natal homing behaviour, meaning they return to breed in the same area where they originated. However, not all individuals return to their natal breeding grounds—a behavioural trait known ... -
Seasonal variation in growth, consumption and growth efficiency in overwintering juvenile steelhead
(Peer reviewed; Journal article, 2019)Food availability and thermal regimes can largely govern growth opportunities in fishes. In temperate regions, streams can exhibit summer temperatures that exceed the optima for coolwater-adapted species relative to the ... -
Stable isotopes and gut contents indicate differential resource use by coexisting asp (Leuciscus aspius) and pikeperch (Sander lucioperca)
(Journal article; Peer reviewed, 2018)Differential use of habitat and prey resources is an important mechanism that may allow coexistence of sympatric species. Unlike interactions between smaller cyprinid and percid fishes, the resource use by coexisting ... -
Swimming performance of brown trout and grayling show species- specific responses to changes in temperature
(Journal article; Peer reviewed, 2018)Fishways have historically been constructed to restore and preserve the ecological connectivity for fish in fragmented rivers. However, the fishways are often selective on species due to different size and swimming capacity. ...
