Most of us working on behalf of wild steelhead love our jobs. Still, after a long week we are ready to hit the water — and share some more Science Friday steelhead knowledge. This week we touch on a study conducted by Andrew Brown at the University of Washington, along with several co-authors. The paper is here: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0059162 …
Science Friday: Predictions for Columbia/Snake River summer steelhead and a new study on ocean distribution
Winter steelhead season is winding down, if not over in some rivers. Time to regroup and prepare for summer runs! This Friday we have a science two-pack for you. First, a bit of cautious optimism. More steelhead are predicted to return to the Columbia River basin this year than in the past two years. Last year the upriver …
Science Friday: How does catch and release affect steelhead?
Today we review a study on the impacts of catch and release angling on wild steelhead in the Bulkley River, the largest tributary to British Columbia’s legendary Skeena system. Conducted by Will Twardek and several others, this study looked into the effects of catch and release, air exposure and fight time on behavior and survival to spawning. The study …
Science Friday: Behavioral Thermoregulation
Most steelhead anglers know that the family of fishes called salmonidae (trout, char, salmon and whitefish) are highly sensitive to water temperature and quality. These fishes require cold, clean water to thrive. But what happens to them when water temps become unfavorable? As you might expect, they seek out places in the river that regain cool water — now often …
2017 – a Bad Year or Part of a Trend?
Ocean conditions are vitally important for wild steelhead runs — probably every steelhead angler knows this. But what does that phrase really mean? The ocean is a massive and incredibly complex system, and there are many factors out in the big blue that can influence steelhead in any given year. That is why it is so difficult to parse out …
