Photo Essay: Tracking Salmon at Montana Creek

Photos and captions by ACRC volunteer Brennen McCulloch. Brennen accompanied graduate students Kevin Fitzgerald and Lindsey Call conducting fieldwork at Juneau's Montana Creek in October 2022, to collect juvenile salmon as part of an effort to understand how nutrients move from streams out to the ocean and how salmon growth fares in changing stream conditions.

Kevin Fitzgerald pricks a pouch of cured salmon egg bait among minnow traps on the bank of Montana Creek. The eggs are used to attract juvenile salmon to the traps for study. The juveniles are weighed, measured, and scanned for PIT tags (to see if they have been examined during a previous field outing) before being returned to the creek where they had been caught.

The juvenile salmon are weighed, measured, and scanned for PIT Tags. Those with tags have been caught before so their length and weight data can be compared to previous measurements to analyze their growth.
