Critical Swimming Speed and Metabolic Activity as Predictors of Ecologically Relevant Behaviour in Juvenile Rainbow Trout (Onchorhynchus mykiss)
DownloadSpring 2019
Swimming ability in fish is vital for survival since it relates to behaviours such as avoiding predators, capturing prey, migration, and reproduction. Critical swimming speed is the most commonly used measure to quantify swimming ability, and so it is often assumed to be a good indicator of...

For many fish, their olfactory system allows for the critical detection of environmental chemical cues indicative of food, predators, kin and mates. Through odourant recognition, fish are able to react appropriately to their environment and elicit behaviours necessary for survival. The central...

Life history strategies of northern form Dolly Varden (Salvelinus malma malma) in the western Canadian Arctic
DownloadFall 2017
Northern form Dolly Varden char (Salvelinus malma malma) inhabit cold-water streams in the western Canadian Arctic. They are an important cultural and subsistence resource to local Aboriginal communities, yet little is known about their complex early life histories. Populations of Dolly Varden...

Fall 2018
The continuing use of crude oil and development of the oil industry have resulted in complex hydrocarbon mixtures becoming common environmental contaminants. These contaminants, such as oil sands process affected water (OSPW) and crude oil, are especially of concern in aquatic ecosystems. OSPW...

The migratory life history and physiology of arctic char, Salvelinus alpinus, navigating change in the Canadian North
DownloadFall 2015
Global climate change (GCC) is most pronounced at higher latitudes; to what degree northern migratory fish species can tolerate this change remains largely unknown. Imminent effects of GCC on arctic rivers include warmer water temperatures and changes in the timing, frequency and magnitude of...

Toxicological Characterization of Hydraulic Fracturing Flowback and Produced Water Exposures to Aquatic Organisms
DownloadFall 2021
Hydraulic fracturing is an unconventional oil and gas extraction method used to liberate oil and gas reserves from low permeability geological formations by injecting large quantities of fracturing fluid into the well-bore under high pressures. A by-product of this process is flowback and...

Trophic ecology of culturally important subsistence fish species and assessment of diet overlap with range-expanding chum salmon (Oncorhynchus keta) in the Canadian Arctic
DownloadFall 2024
Rapid climate change is occurring in the Arctic and has the potential to affect the diets and trophic dynamics of northern fish species, many of which hold great cultural value to northern communities. Fully understanding the trophic ecology of such fishes allows us to better understand their...
