Examples
Finding out what’s been tagged
Particular issues
• Adult steelhead stray rates
• Sub-yearling migration behavior
• Sockeye survival

Potential issues
Purpose not captured in database
Changing environment and methods
Data quality
• Over 25,000,000 tags
• Numeric/character format
![Page 19: Josh Murauskas Natural Resources Department Chelan County PUD](https://reader038.vdocuments.net/reader038/viewer/2022103123/56649d155503460f949e9c33/html5/thumbnails/19.jpg)

Conclusion
1. Plenty of data available
2. Metadata = better than memory
3. You may not need another study
• Maybe someone did it already
• Maybe you’re not that bad after all
4. Your neighbors have dirty secrets
