I find it hard to believe any species that feeds so selectively on a single prey, is not capable of changing its hunting areas has any chance of survival. Why don’t the whales move to any area of more abundance? Surely they would be better feeding in areas with less population and fishing pressure, yet they only are capable of feeding in the area around Victoria and Vancouver? Is it plausible an animal this smart would starve rather than modify its diet?
I can see if the study that claims they rely so heavily on Springs for sustenance was perhaps done during a Spring run. I can also see where all these proposed closures close to Vancouver and Victoria would be good for enticing whales for whale watchers. Sure as hell think there is more politics than science in play here.
