What is a B-run steelhead?

In Oregon, Science Friday by Nick Chambers

Fisheries managers predict this will be a very bad year for returning B-run steelhead in the Snake River. The Snake, with its headwaters straddling the Teton Range on the Idaho-Wyoming border, is the largest tributary to the Columbia and its intact habitat and steelhead runs are vital to the overall health of Columbia River steelhead populations. Despite the high quality …

Science Friday: The life stages of juvenile steelhead

In Oregon, Science Friday by Nick Chambers

We have spent the last several weeks introducing and defining a variety of terms used in steelhead management. This week, we shift to looking at terms related to steelhead biology, specifically terms used to describe different life stages of juvenile steelhead.   Let’s start with eggs. These are the little round suckers that produce the fish. Seriously, everyone understands the …

Science Friday: What is introgression?

In Science Friday by Nick Chambers

For this edition of Science Friday, we continue to define terms used in studies that evaluate hatchery steelhead (and often other species of salmon and trout). Last week we defined fitness and discussed how it is measured and why it is important to understanding the biology of steelhead. This week we take another step into the deeper end of the …

Steelhead 101: Using weirs to estimate adult steelhead escapement

In Oregon, Science Friday by Nick Chambers

Recently we have described how scientists use redd counts and snorkel surveys to estimate steelhead escapement. This week we focus on weirs, a totally different way of counting steelhead. Rather than sending out surveyors to sample stretches of stream where they count redds or fish, the operation of a weir is much simpler. A weir basically blocks the river and …

Steelhead 101: Using snorkel surveys to estimate adult steelhead escapement

In Alaska, California, Idaho, Oregon, Science Friday, Washington by Nick Chambers

Another week, another post on how scientists and fisheries managers measure steelhead escapement. Last week, we described redd counts and why they are an important tool. This week, we review snorkel surveys.   Snorkel surveys entail divers swimming in the river and visually counting adult steelhead. Like redd counts, snorkel surveys do not cover an entire river, but rather break …

Wild Rivers, Wild Steelhead

In Oregon, Washington by Nick Chambers

What are the keys to successful wild steelhead conservation? What can you do to help this cause? How do steelhead differ from other salmonids in their sexual behavior? For answers to these and many other questions about wild steelhead, as well as some of the best steelhead stories ever told, please join Wild Steelheaders United for an evening of science, …

Angler Science opportunities in Washington

In Science Friday, Washington by Nick Chambers

It is that time of year again where we all get the opportunity to become citizen scientists on the weekend (basically, we get to have fun playing in streams).   I am happy to inform you all that – like last year – TU and Wild Steelheaders United will be conducting steelhead redd surveys in Washington’s Hoh River and sharing …

The Wild Steelheader Dec. 2016

In Newsletter: The Wild Steelheader, Oregon by steelheaders

 December 28, 2016 It’s been more than two years since Trout Unlimited’s Wild Steelhead Initiative left the boat ramp. This initiative was born of committed steelhead anglers whose hope for a brighter future for wild steelhead is matched by their stubbornness in fighting for the improvements in habitat and policy required to realize this vision. For too long, steelhead management …
