Smolt trap
Captured smolts are measured and weighed
We PIT tag a subsample of steelhead juveniles over 100 mm
PIT tagged smolts are released above the trap once a week to estimate efficiency
DNA samples
Scale samples
Notes:
We empty the screw traps every day including weekends
The smolts are weighed and measured
A subsample is PIT tagged to look at survival and migration timing
Once a week, PIT tagged individuals are released several hundred meters above the trap to estimate efficiency
DNA and Scale samples are collected
