B.C. waters become a whale-sighting hotspot as food supply recovers

A combination of healthy food supplies and conservation measures has made British Columbia’s Salish Sea a frequent place to spot whales, according to marine experts. Marine biologist Julia Adelsheim of Wild Whales Vancouver said recent sightings of orcas, humpbacks and other marine mammals along the province’s southern coast reflect real population gains, not just social media attention. She pointed to research showing transient killer whales are spending much of the year in the area, while humpbacks have returned to feed there after years of decline. Adelsheim said the summer season also plays a major role, since longer daylight and warmer conditions boost algae and plankton, which support fish and, in turn, larger marine animals. She added that past protections, including the end of commercial whaling and seal culling, have helped whales recover in local waters. The article also notes concern for grey whales, which have been seen near Vancouver but are facing food shortages in their northern feeding grounds. Marine scientists say climate change may be affecting the availability of prey, and officials are urging the public to follow distance rules to help protect the animals.
