GSI on wild stocks. Can now report wild abundance by reporting group not just the total return to LGR
Ability to use PBT to identify hatchery fish
Transitioning to PBT based sampling for harvest estimates in sport and tribal fisheries

12. Comparison of Chinook and Steelhead sport harvest Chinook harvest includes jacks
Chinook harvest includes adults and jacks (jacks are defined in regulations as fish < 24 inches total length).

13. Yearly Angler effort (days fished)
Chinook effort was estimated as hours fished. I converted it to days fished by assuming 1 day = 6 hours fished.
Steelhead effort was estimated as “days fished”
