Blue herons identified as a significant predator of B.C.’s juvenile salmon

Pinnipeds, cormorants, Caspian terns, now blue herons.

This predation could benefit salmon stocks by weeding out the weak and allowing for less competition and higher growth among other fish in these critical juvenile life stages.
