There's so much to do to help the Chinook Salmon, Leo has the team split up to complete their mission. Christian's going electrofishing, but not with the usual high-tech backpack. This time, he's on a boat with Toronto and Region Conservational Authority that controls the shock with a foot pedal! While he's monitoring the salmon, Sayat helps clear a fish-ladder, which assists the salmon with their uphill climb upstream to lay their eggs.
