It’s steelhead fryday and we have you covered with a look into the early life stage of steelhead and the various types of behavior and biology at play.
Science Friday: Update on the Hood Canal bridge and survival of steelhead smolts
This week’s Science Friday is an update on a topic we have covered before: the effect of the Hood Canal bridge on survival of steelhead smolts passing through Hood Canal.
Meet the team: John McMillan
We’re rolling on with Elwha week with more content on the people that have helped make the Elwha the Phoenix Rising from the Ashes. Today, we have the next post in our Meet the Team series featuring our Science Director for the Wild Steelhead Initiative, John McMillan. You may already know John from his Instagram account @rainforest_steel, or his Barbless …
Science Friday: Big fish, big streams; little fish, little streams
A holiday weekend deserves a new Science Friday post. So here we go. This week we focus on summer steelhead in the John Day River, a large tributary that drains into the middle Columbia River on the Oregon side. The John Day is a big watershed, covering 8,000 square miles, although the river itself is not that large. To …
What is a B-run steelhead?
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
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?
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
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
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
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, …
