Continuation of our Science Friday Series: Untangling Steelhead and Rainbow Trout Dynamics
Should I Stay or Should I Go?
Untangling Steelhead and Rainbow Trout Dynamics in Washington’s Hood Canal: Part 1
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.
Science Friday: Oldie but a goodie on steelhead fry behavior in intermittent streams
This week we review a Master’s Thesis from John David Faudskar, conducted when Faudskar was at Oregon State University in 1980. This study examined how young steelhead behaved during their first summer of life in the Rogue River watershed in Oregon.
Science Friday: Juvenile steelhead finding refuge in tributary mouths
Summer is over, but before we put it behind us, it’s worth considering that the summer of 2020 was likely one of the two hottest summers in the northern hemisphere since humans began measuring the temperature of air and water. Hot temperatures directly—and sometimes dramatically—affect steelhead and many other salmonid species. So our Science Friday review this week of a study of steelhead in California’s Eel River is timely.
Science Friday: Juvenile steelhead feast or famine depending on the number of spawning salmon
In this week’s Science Friday post, we discuss a new paper where we show how high numbers of salmon may be more important than we previously thought for steelhead.
Science Friday: How do salmon and steelhead in the ocean find their way home?
Have you ever wondered how salmon and steelhead navigate in the big blue? It’s not like there is a road map, or a GPS – or is there?
