Tag, You're It: Tracking the Grand Canyon's Toughest Fish

Season 2 Episode 5 | 4m 35s

Biologist Lindsay Hansen and her USGS team work day and night to study the federally threatened humpback chub in the Grand Canyon. Using PIT tags, they track fish growth and migration to understand how this resilient species adapts to cold dam flows and warming tributaries like the Little Colorado. Their efforts offer a glimpse of hope in an altered ecosystem.
