A potential growth thermal index for estimating juvenile Atlantic salmon ( Salmo salar ) size‐at‐age across geographical scales.
We present a potential growth thermal index (PGTI) and assess its correlation with juvenile Atlantic salmon Salmo salar fork length data collected near the end of the growth season in a range of latitudinal locations and geographic scales (watershed, regional, continental) across the American north‐...

We present a potential growth thermal index (PGTI) and assess its correlation with juvenile Atlantic salmon Salmo salar fork length data collected near the end of the growth season in a range of latitudinal locations and geographic scales (watershed, regional, continental) across the American north‐east. The PGTI is based on two components: a water temperature‐dependent growth curve and a water temperature time series continuously describing the thermal environment preceding fish sampling. Testing various shapes and characteristics of the temperature–growth curve against fish length data revealed strong positive correlations for all combinations.
