As we all know, shortfalls in funding for our fish and wildlife management agencies are an ongoing concern. Severe budget constraints play out in many ways that impact fisheries management and sometimes angling opportunity. TU and Wild Steelheaders United are working both on-the-ground and in the halls of state legislatures to address these funding challenges. One of the first important …
Stock Recruit Curves And Wild Steelhead, A Good Match?
In several recent posts we have discussed the concept of density dependence and how it is used in fisheries management. Today we dive in deeper and talk about the stock-recruitment relationship, density dependence, and how the results of such models are applied to managing steelhead. First, let’s define some terms. Stock refers to, in this context, a population of …
Science Friday: Why do juvenile steelhead move at the onset of winter?
By John McMillan We are going old school today, Science Friday style. No, we’re not talking about shooting ourselves with a tranquilizer gun, going streaking, or starting a fraternity to compensate for a mid-life crisis. We’ll leave that to Will Ferrell. But we are going back in time, to 1971. Today we revisit one of the foundational pieces of …
Science Friday: Steelhead fry party when the lights go off — but will they wake up high and dry?
In our last Science Friday post we took a look, in part, at the feeding behavior of bass. This week we are moving down in the feeding column to focus on catfish. Just kidding. It’s all steelhead all the time here. Today we review a paper by David Hines and several colleagues. The study focuses on the behavior …
A thorny challenge on the Deschutes River
Trout Unlimited is working to ensure the success of the Pelton-Round Butte Fish Passage Program and conservation of lower River angling opportunity If you’re a trout or steelhead angler in Oregon, you’re probably at least somewhat familiar with issues related to fish passage and native fish on the Deschutes River. Trout Unlimited has been working for the past several …
Science Friday: Are some fish caught more than others, and if so, why?
We’re deep in the heart of winter steelhead season now. But if you’re like us, you are probably suffering from high-wateritis right about now — a common affliction for winter steelheaders. Living on the Olympic Peninsula, I have it bad. Non-stop rain for days. Rivers punched. Headaches due to lack of chrome-ium. Conditions better improve quickly…or I might not …
Science Friday: Space, time, and maximizing habitat capacity
All steelhead, all the time, here at Wild Steelheaders United. Over the past few weeks we have examined the scientific concepts and tools used to evaluate how productive a given stream can be for wild steelhead. Such assessments are an important component of managing a steelhead fishery — especially if the run in that watershed is ESA-listed (in the Lower …
Science Friday: The importance of both space and time in managing wild steelhead
This is the third of four posts on the nuts and bolts of estimating wild steelhead populations, spawning success, and other key management variables. First, we covered the concepts of carrying capacity and density dependence and how habitat can be used to estimate carrying capacity. Last week’s post shifted gears to review studies that found the spatial distribution …
Cutting TLMP threatens Tongass Steelhead
The incredible fishing opportunity in Southeast Alaska’s Tongass National Forest has survived despite years of timber wars across the region. Logging the impressive old growth trees of the Tongass poses direct threats to wild salmon and steelhead by increasing the amount of sediment in streams, raising water temperatures and removing key spawning habitat. However, with a recent amendment to …
Snake River Steelhead Recovery Plan Released by NOAA
By Rob Masonis The recent release of the final federal recovery plan for Snake River Spring/Summer Chinook salmon and steelhead is a milestone in the decades-long effort to reverse the precipitous decline of salmon and steelhead runs in the Snake River system. The Snake was historically the most productive region in the Columbia Basin for spring/summer chinook and steelhead, …
