Spatial ecology of Arctic Grayling in the Parsnip core area

This project will investigate the spatial ecology of juvenile and adult Arctic Grayling and their interactions with Bull Trout in the Parsnip River and its tributaries. The objectives will be addressed using a combination of approaches including acoustic telemetry, capture-recapture, temperature data logging, stable isotope analysis and spatial modelling. The findings of the project will address a number of moderate and high immediacy data gaps related to: 1) the spatial ecology (migration, distribution, and habitat use) of Arctic Grayling that were identified for the Parsnip River core area; and 2) potential interactions with Bull Trout, which may be limiting the growth of Arctic Grayling populations throughout the Williston Reservoir watershed.
