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 WDFW Internal Evaluation of Coastal Steelhead Hatchery Programs Points to Needed Changes
In late August, WDFW published a white paper that highlights data gaps and lack of compliance with Statewide Steelhead Management Plan guidelines for coastal steelhead hatchery programs.
Hatcheries can’t save Snake River salmon and steelhead
Today, there are many so-called “mitigation hatcheries” in the Snake River basin that are intended to produce enough salmon and steelhead to make up for the wild fish that were lost when their habitat was blocked by dams.
Science Friday: How do steelhead survive in intermittent streams?
It’s the first Friday in October — officially, “Septober” for us steelheaders. Unfortunately, steelhead runs across much of the West Coast have been down this year, and now there is another blob of warm water in the North Pacific. Things don’t look good right now, but wild steelhead have withstood these types of conditions before. As long as we …
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 usage by adult steelhead. Today …
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 as well as the genetic …
The General Practitioner
By: Sean Dahlquist Today’s post was graciously provided by Sean Dahlquist. Sean lives on the Olympic Peninsula, where he loves fishing for steelhead and trout, and of course, tying flies. Not only is Sean a fine tier, but he is also a historian on the topic. Check out Sean’s Instagram @sean_dahlquist page for more great patterns and examples. …
Science Friday: The latest from the longest running steelhead monitoring project in British Columbia
Thank goodness it’s Friday. Fall is in the air and it’s time to get on the river! But first, let’s give our steelhead IQs another booster shot with a new Science Friday post. This week we have a guest writer and scientist, Colin Bailey, a PhD student studying fisheries science at Simon Fraser University under Jonathan Moore (Moore …
Science Friday: Surviving heat, drought and ponded streams
It is that time of year again. Heat wave after heat wave. As summer progresses stream flows will continue to decline all across steelhead country, and in some cases, smaller tributaries will go dry. In other cases, streams won’t be completely dewatered; instead, they will become ponded. This occurs when flows diminish so much that the only remaining surface …
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 …
