Global warming affects start of salmon season

This article was interesting. They talk about the late spawning of salmon, and how the fish have been thrown in to confusion by the climate. Some of the fish caught on opening day for the past five years are fish that haven't spawned yet. About 60%. Some of the anglers want to change the opening date from the month of January to February. They say that it isn't right to disturb breeding fish. I think that it isn't right to disturb animals when they are breeding it can affect the species in the long run.
