5. Stock-recruitment curves
6. Biological data (genetics, sex ratio, spring stock distribution)
7. Electrofishing surveys
8. Categorisation

7. Aquaculture interactions
1. Smolt distribution (tracking, modelling)
2. Sea lice distribution (sentinel cages, modelling)
3. Sea lice impact assessment
4. Risk mapping

8. Climate change
1. Environmental change (chemistry)
2. Temperature models (empirical, process-based)
3. Mitigation (tree planting, discharge regulation)

9. Strategic data networks
Existing
•Catches
•Temperature
•Upland waters: chemistry, inverts, fish
•Sea lice sweep nets
•Beaver woodland

10. 3. Strategic data networks
Developing and future??
•Lice impact/marine survival/(seal impact?)
•Counters
•Smolt emigrant data
•Smolt tracking data
•Fishing Effort (S Esk report)
•Electrofishing
•Predator counts?
•Predator damage?
•Predator impacts?
•Coarse fish etc??
