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 … Continued

eDNA and O. mykiss, part II

Natalie Stauffer-Olsen   Two weeks ago we looked at the use of eDNA in monitoring for the presence or absence of aquatic species. While our post was not a comprehensive review of this subject, we did include some of the most promising aspects — and some of the challenges — associated with using this new … Continued

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, … Continued

Science Friday: What happens when you cram the big’uns in with the small’ins?

We sure do love this beautiful weather! It’s almost the first day of June. Summer is officially within sight.   This week’s Science Friday goes back in time over 20-years to 1997.  We review a study conducted by Brett Harvey and Rodney Nakamoto. We have reviewed some of their work previously, which focused on habitat … Continued

Science Friday: Successful habitat restoration on the Washougal River

Welcome to another Science Friday post from Wild Steelheaders United. In this space we usually review scientific studies that have implications for wild steelhead conservation and management. But we take a slightly different path this week. I was born and raised on the banks of the Washougal River in SW Washington. The poor Washougal has … Continued

Science Friday: Why is your lateral line different than mine?

Most of us working on behalf of wild steelhead love our jobs. Still, after a long week we are ready to hit the water — and share some more Science Friday steelhead knowledge.   This week we touch on a study conducted by Andrew Brown at the University of Washington, along with several co-authors. The … Continued

Science Friday: When fish grow and die in California

Soquel Creek is a small stream flowing into Monterey Bay about 70 miles south of San Francisco and is home to a population of winter steelhead. A group of scientists published a paper in 2009 that looked into seasonal patterns of growth, survival and movement of age-0 and age-1+ juvenile steelhead within this small California … Continued

Science Friday: Predictions for Columbia/Snake River summer steelhead and a new study on ocean distribution

Winter steelhead season is winding down, if not over in some rivers. Time to regroup and prepare for summer runs!   This Friday we have a science two-pack for you.   First, a bit of cautious optimism. More steelhead are predicted to return to the Columbia River basin this year than in the past two … Continued

Lessons from a steelhead rescue and captive rearing program on California’s Carmel River

By: Natalie Stauffer-Olsen, Staff Scientist, TU’s California Science Program   One of the things that I have always admired most about O. mykiss is how adaptable and resilient they are. The rainbow trout, in both its resident and anadromous forms, evolved to take advantage of the most abundant habitats for their different life history stages … Continued

A follow up to last week’s post: What is happening to steelhead in Hood Canal?

Last week we reviewed a study on a novel hatchery steelhead program that was implemented in a Hood Canal stream to help save and rebuild a population of wild steelhead that were on the brink.  As part of the post, we highlighted the non-traditional methods that were used and why those may have helped the … Continued
