The Pacific Northwest just experienced one heck of an abnormal heat wave. Temperatures soared up to, and in some places beyond, 117F. These are extremely warm temperatures for late June, and the sharp increase had an effect on emergence timing of juvenile steelhead, which we dive into for Field Day Friday.
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 …
Science Friday: The life stages of juvenile steelhead
We have spent the last several weeks introducing and defining a variety of terms used in steelhead management. This week, we shift to looking at terms related to steelhead biology, specifically terms used to describe different life stages of juvenile steelhead. Let’s start with eggs. These are the little round suckers that produce the fish. Seriously, everyone understands the …
How many steelhead can you fit into a school?
It depends on how old and big they are. Over the past year we have talked extensively about the value of life history diversity in steelhead, and in particular, that a broader range in spawn timing – which results in a broader range of emergence for juveniles – can help ameliorate density-related impacts by spreading steelhead of various ages …
