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.
A Portfolio Approach to Management: The Future of Puget Sound Steelheading
For the past three years, a diverse group of anglers with a shared passion for Puget Sound steelhead have worked to develop a portfolio of watershed-specific conservation, fishery, and hatchery strategies for that population. We’re excited to share with you a sneak-peek of the Quicksilver Portfolio.
The Choice for Hatchery Residual Steelhead
Do you know that not all hatchery steelhead smolts actually migrate to the ocean? Some remain in freshwater. Either way, these O. mykiss face a future that could be heroic (survive long enough to mate with a wild steelhead adult female) — or not-so-heroic (survive the summer in freshwater but perish during the difficult conditions of the winter). We …
Science Friday: What is PNI about and why is it important?
Another week, another Science Friday post from Wild Steelheaders United. Last week we discussed the acronyms used in hatchery literature and management plans. Now we narrow the focus a bit to understand how these acronyms are used with one another to evaluate genetic risks associated with hatchery programs — we even offer some formulas for you to geek out on. …
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 …
