Science Friday: Are some fish caught more than others, and if so, why?

In Science Friday by Nick Chambers

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

In Science Friday by Nick Chambers

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

In Science Friday by Nick Chambers

  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 …

Upcoming Public Meetings for Skagit Catch and Release Fishery

In Washington by Nick Chambers

One of the few real success stories in steelhead conservation over the past decade is the comeback of wild steelhead in the Skagit River system. As we have been saying for several years, the rebound of this population has been substantial enough to consider re-opening the Skagit for a spring steelhead season. Wild Steelheaders United and other angling advocates have …

Science Friday: Juvenile Density, Distribution and Habitat Capacity

In Science Friday by Nick Chambers

By John McMillan New Year, new Science Friday! Last week we looked at the concept of carrying capacity, how it is estimated, and the most important habitat factors used to come up with those estimations. This week we shift gears a bit and review studies that illuminate how patterns in fish distribution can affect assumptions about carrying capacity.   Recall …
