The northwest corner of California, between the Russian and Klamath Rivers, is home to some of the best remaining salmon and steelhead streams in the West. This region boasts some of the most famous steelhead fisheries in the world, including the Trinity, Mad, Mattole, and Eel River systems. Trout Unlimited’s North Coast Coho Project has been working for …
The Salmon Coast
The Olympic Peninsula is home to some of the last great places for wild salmon and steelhead in the Lower 48. Of course, it’s the wild steelhead that draw many of us to the OP. But it’s also the huge trees and beautiful brawling rivers that make the OP a destination for fish and anglers alike. While much of …
Science Friday: How does catch and release affect steelhead?
Today we review a study on the impacts of catch and release angling on wild steelhead in the Bulkley River, the largest tributary to British Columbia’s legendary Skeena system. Conducted by Will Twardek and several others, this study looked into the effects of catch and release, air exposure and fight time on behavior and survival to spawning. The study …
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 …
Science Friday: Do these lipids make me look fat?
For most anglers who have encountered both winter and summer steelhead, it’s abundantly clear there are differences between the two races of fish. For one, they enter freshwater at different times of the year, although there is some overlap. In addition, there are physical differences. Summer steelhead tend to be more fusiform — sleeker and more firm bodied …
Science Friday: Certain genetic families survive better in hatcheries and might help explain why hatchery steelhead do poorly in nature
Spring is here and we’ve got a real shot of warm weather on the West Coast. Certainly, spawning steelhead appreciate the ecological effects of this boost in thermal energy. Last week we reviewed a recent paper on repeat spawning in steelhead in the Hood River, Oregon. This week, we return to the Hood to look at another paper out …
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: Why are half pounders declining in the Trinity River?
When anglers dream of steelhead, they mostly fantasize about fish that have spent 2-4 years in the ocean and return to freshwater to spawn as full adults, packing four or more pounds and brutish power into their physique. However, one of the most common forms of returning steelhead in some rivers is not the adult, but the so-called half-pounder. …
Science Friday: What the heck do all those acronyms mean?
Science Friday! Another chance to dive into the weeds and define some of the jargon used when discussing, studying and evaluating hatchery steelhead. This week we focus on acronyms commonly used in hatchery management plans. Anyone who has read through a Hatchery Scientific Review Group plan or review, or most any resource management plan for that matter, has probably …
