In this week’s Science Friday we take a close look at the lessons provided by a recent report on the PNW’s network of Intensely Monitored Watersheds.
Hatchery Selection and the Effects of Egg Size on Steelhead Growth and Development
In this week’s Science Friday we examine a new study that sheds light on the alarming mechanisms and impacts of the rapid shift in egg size of fish reared in hatcheries.
A New Scientific Resource to Better Understand the Global Impacts of Hatchery Fish on Wild Salmonids
A literature Review led by Trout Unlimited shows over 80 percent of global, peer-reviewed research on the topic has found an adverse effect on wild salmonid populations in freshwater and marine environments.
Steelhead Conservation in Washington’s 2023 Legislative Session
Last week, the Washington State Legislature kicked off its 2023 legislative session. A few priorities this year that we will be working on include an important policy bill, and several funding items important to steelhead management and recovery.
Key Questions Surrounding the WDFW’s Hatchery White Paper
In Part Two of our hatchery white paper review, our Science Advisor provides further insights into the impacts of hatchery steelhead management on Washington Coastal systems.
NORTH UMPQUA UPDATE – STATUS OF HATCHERY SUMMER STEELHEAD PROGRAM
Read the latest on the status of the North Umpqua hatchery summer steelhead program.
Much at stake in listing decision on Northern California summer steelhead
We love all steelhead here at Wild Steelheaders United, but some anadromous O. mykiss populations may deserve more love than others. Consider wild summer run steelhead in Northern California. The available data for wild summers between Redwood Creek and the Gualala River (including the legendary Eel River watershed) suggest their numbers are greatly depleted — probably enough to warrant …
Carving a path through the debate over upper Willamette steelhead
Carving a path through the debate over upper Willamette steelhead There are no easy decisions in the world of steelhead conservation and management, but some issues are more difficult than others, such as hatcheries. Although the science on hatcheries is solid and critical to guiding management of wild steelhead, there is a role for hatcheries, as long as …
Science Friday: The value of new technology: eDNA and O. mykiss
By Natalie Stauffer-Olsen It is always exciting when new technology becomes available that can help us understand, manage and protect wild steelhead, the mavericks of the Pacific salmonids. Steelhead and rainbow trout populations can be difficult to predict, model and understand because of their very plastic (scientific term for highly variable) life histories, from juveniles to adults. What’s …
Science Friday: Revisiting the Carmel River Steelhead Mitigation Program
Written by Natalie Stauffer-Olsen, PhD, TU Staff Scientist Every now and then we publish something that prompts a reaction from the authors of a report we analyze or others in the science world. This happened with our recent post on the Carmel River that focused on some biological and ecological aspects explored in the paper “Size-conditional smolting and the …
