The general goal of our movement ecology projects is to determine the causes and consequences of freshwater fish movements over small and large spatial scales.

MOvement ecology of white sturgeon in the columbia river

This project is using an existing long-term data set on acoustic telemetry of wild white sturgeon to characterize their movement patterns in relation to flow regulation by hydropower dams in the Columbia River. The project also involves acoustic tagging of hatchery-reared white sturgeon to address questions associated with potential interactions with wild fish and transboundary movements. This project is funded by BC Hydro.

Spatial ecology of arctic grayling in the parsnip watershed

This project is investigating the spatial ecology of juvenile and adult Arctic grayling and their interactions with bull trout in the Parsnip River and its tributaries. The objectives are being addressed using a combination of approaches including acoustic telemetry, capture-recapture, temperature data logging, stable isotope analysis and spatial modelling. If you are an angler fishing in the Parsnip and tributaries and happen to catch one of our tagged fish, please let us know the tag number, date and location of capture. You can either contact us directly or report the capture via the MyCatch app or our project page on the Angler's Atlas website. This project is funded by the Fish and Wildlife Compensation Program.

HABITAT USE AND MIGRATION of Fishes in the Amazon

This project is using radio and/or acoustic telemetry to investigate habitat use and migration of several Amazonian fishes, including arapaima (Arapaima spp), arowana (Osteoglossum bicirhossum), redtail catfish (Phractocephalus hemioliopterus) and goliath catfish (Brachyplatystoma spp.). Study sites include long stretches of the Xingu and Madeira Rivers and associated hydropower facilities, as well as floodplain lakes of the Purus River.

ACTIVITY of arapaima during the dry season

This project is using accelerometer data loggers to investigate the activity and to identify behavioural modes of arapaima (Arapaima spp.) confined to floodplain lakes during the dry season in the Amazon.


This project is using existing water temperature and radio-telemetry data to investigate how variability in thermal experience affects the survival of adult migrating Fraser River sockeye salmon from populations exhibiting different thermal tolerances.
