Research Topic: Movement and trophic ecology of Arctic fishes

My research is focused on the movement and trophic ecology of Arctic fish species. During the summer of 2018, I spent 9 weeks in the Canadian high Arctic (near Pond Inlet, Nunavut) implanting acoustic telemetry tags into Arctic char and sculpin. To monitor their movements, we deployed an extensive array of acoustic telemetry receivers to detect tagged fish. Additionally, I dissected some individuals to obtain stomach contents, which I will analyze to understand consumption rates and diet. This research aims to understand how movements and feeding of Arctic fishes are influenced by environmental variability, particularly during spring ice-off.
