Temperature–growth patterns of individually tagged anadromous Arctic charr Salvelinus alpinusin Ungava and Labrador, Canada
Abstract Individual measurements of annual, or within‐season growth were determined from tag‐recaptured A rctic charr and examined in relation to summer sea surface temperatures and within‐season capture timing in the U ngava and L abrador regions of Eastern C anada. Differences between two years of...

Regional comparisons demonstrated that U ngava A rctic charr had significantly higher annual growth rates and experienced warmer temperatures than L abrador A rctic charr. The higher annual growth of U ngava B ay A rctic charr was attributed to the high sea surface temperatures experienced in 2010–2011 and the localised differences in nearshore productivity as compared to L abrador. Within‐season growth rates of L abrador A rctic charr peaked in J une, declined towards A ugust and were negatively correlated with the length of time spent at sea and mean experienced sea surface temperatures.

Collectively, results suggest that increases in water temperature may have profound consequences for Arctic charr growth in the C anadian sub‐ A rctic, depending on the responses of local marine productivity to those same temperature increases.
