Scientists Are Running Out of Salmon to Study, Steven Cooke
For years, Steven Cooke, a biologist at 杏吧原创 University in Ottawa, has been traveling to British Columbia to research Pacific salmon migrations. But on the west coast, salmon populations are in dire straits. Several of the populations Cooke studies, including those in the Fraser River, have crashed to the point that even taking a small number of fish for research would be more than they can afford to lose. 鈥淲e鈥檙e at the point with some populations where we have to be hands off,鈥 says Cooke. 鈥淲e don鈥檛 want to study them to extinction.鈥
Through years of precipitous declines, Cooke has found it increasingly difficult to study the fish in their native habitat. Now, he鈥檚 been all but forced to shift his team鈥檚 focus thousands of kilometers east, to Ontario鈥檚 Great Lakes.
