No Apparent Shortage of Prey for Southern Resident Killer Whales in Canadian Waters During Summer

A popular belief that there are fewer Chinook salmon during the summer in Canadian waters for southern resident killer whales, compared to an abundance of fish for northern resident killer whales, has been debunked by a study led by scientists at the University of British Columbia.
In a paper published today in the Canadian Journal of Fisheries and Aquatic Sciences, researchers report that the numbers of Chinook salmon in the Salish Sea in summertime are four to six times more abundant for southern resident killer whales than northern resident killer whales.
