The World Wildlife Fund is concerned about the dwindling salmon numbers in the Thompson River.
The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) reported this week that of 16 Chinook populations studied, eight are endangered, four are threatened and one is considered of special concern.
World Wildlife Fund Species Specialist Emily Giles says the dwindling numbers can be attributed to a couple of reasons.
"The most common threats facing all of them are things like fishing, and habitat degradation. Salmon live in both fresh and salt water and their habitat is degrading in both those regions."
Giles says that a lack of salmon hurts the food supply for southern resident killer whales as well as grizzly bears and bald eagles, in addition to other wildlife.
