Another Science Friday looking at the fate and migratory oceanic patterns of steelhead kelts from Alaska’s Situk River.
Science Friday (PART TWO): Disappearing Steelhead – The Fate of Summer Steelhead Seeking Coldwater in the Columbia and Snake Rivers
fish traveling downstream through the hydro system, and discussion of possible management changes to help improve steelhead survival.
Science Friday (PART ONE): Disappearing Steelhead – The Fate of Summer Steelhead Seeking Coldwater in the Columbia and Snake Rivers
In the Columbia and Snake rivers hydropower systems, many migrating summer steelhead overshoot their spawning streams, passing dams multiple times and increasing mortality rates, trying to find cold water refuge. We look at the ramifications on steelhead management for not properly accounting for these overshoot steelhead.
Science Friday: It’s not all about steelhead
We look at a new paper that digs into the factors leading harbor seal to prey on juvenile steelhead and the abundance of both coho and Chinook salmon during the steelhead outmigration window to understand how these pulses of hatchery salmon impact the weekly survival of steelhead moving through Puget Sound.

It’s Steelhead Fryday!
It’s steelhead fryday and we have you covered with a look into the early life stage of steelhead and the various types of behavior and biology at play.
Field Day Friday: The high value of two redds in one
Is there anything special about a winter steelhead redd in late May? Perhaps not, in general, but sometimes if we look more closely some interesting details might emerge.
An Attempt to Breed Better Biters Has an Unexpected Twist With Implications for Broodstock Collection
On Oregon’s Alsea River a broodstock program is raising fish using both angler-caught fish and those fish that swim into the hatchery trap. These data beg the question of whether offspring of angler-caught broodstock would be more likely to be caught by anglers than offspring of adults that voluntarily swam into a trap. We dig into a recent study examining this in this edition of Science Friday.
Science Friday: How dam construction — and removal — changed genetics of O. mykiss in the Elwha River
Have you ever wondered how installing a dam, and later removing it, can influence the genetics of a population of migratory fishes? A new study sheds some light on a possible answer.
