A Simon Fraser University study has found that steelhead trout have a remarkable life-cycle variation that responds to changes in temperature and numbers of other species of salmon. They may go to the ocean when they are only a year old and the size of a pinky finger, or when they are five years old and the size of a standard ruler. The study appears this week in the journal Ecosphere.
