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?

In Science Friday by Nick Chambers

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. …
