The two-day Grande Prairie symposium was composed of a series of 20 minute presentations and a field visit to nearby grayling streams. Participants traveled to sites along the nearby Beaverlodge River. The grayling population in this notable grayling stream was extirpated during the 1990s because of unplanned land use and subsequent stream fragmentation and degradation of water quality.
Presentations were organized into four sessions, each focussing on a primary theme:
1. Biology and Natural History
Demographics of sustainable populations,genetic knowledge and implications, migratory needs, habitat requirements,overwintering behaviours.
2. Monitoring Approaches
Measuring abundance, ageing techniques,gear selectivity and catchability, surgical knowledge, telemetry techniques, habitat measurement and monitoring techniques.
3. Threats to Conservation
Case studies and mechanisms of loss caused by forestry, petrochemical industries, hydroelectric projects, agriculture, urbanization, overfishing, cumulative effects, and water quality. How do we anticipate threats posed by climate change, such as changes to flow and temperature, increased fragmentation, recruitment variability?
Case studies of effects of angling size and bag limits, aspects of catch-and-release mortality, habitat restoration projects, restoration stocking, fish passage remediation.
