“It’s changing quite rapidly,” says a hunter in Canada. “And I’m not old at all. I’m 31.”
The state is imposing more restrictions on fishing this year as the combination of extreme conditions, including low river levels, fish die-offs and the crush of anglers, poses long-term problems.
An early estimate points to a huge die-off along the Pacific Coast, and scientists say rivers farther inland are warming to levels that could be lethal for some kinds of salmon.
