Where are the Whales?! « The Marine Detective: "Johnstone Strait is the only waterway that allows full passage on the inside of Vancouver Island and therefore it is like a funnel for the salmon traveling to natal rivers further south to spawn. This is why, most often, there are some families (“matrilines”) of the northern resident population in our area from July into October/November. This is when the salmon are running and the killer whales are especially present when there is the opportunity to pursue fatty Chinook salmon."
