What do the index numbers mean?
I have tried to find an explanation online but can’t really seem to nail down a real easy to understand explanation.
What I do know
1) the numbers are generated from gill netting for 1 hour multiple times a day and at the same location.
2) a higher index means more fish entering the system.
But what exactly does a 32.7 coho or 0.82 steelhead actually mean? And then beyond this what would a good number be?
