A new UBC study found that the endangered Southern Resident Killer Whale population isn’t getting enough to eat.
As lead author Fanny Couture explained, “The study goes from 1979 to 2020. We were trying to understand whether the Southern Resident Killer Whale population had enough food to eat to sustain their energy needs. So a human needs 2,000 calories a day, a killer whale will need about 170,000 calories a day. What we found is that they were in energy deficits for six of the last 40 years. Some of them are spread out throughout the study period, but three of the last years (in the study), 2018 to 2020, they were in full energy deficits. They did not have enough food in the spring, the summer and the fall.”
