Distribution and movement of European grayling in a subarctic lake revealed by acoustic telemetry
Abstract Knowledge of the horizontal and vertical distribution and habitat use of fish in lakes provides insights into the ecology, evolution and conservation of a species. Using high‐resolution, high‐frequency sampling, we provide an account of the distribution and movements of adult European grayl...
