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.
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.
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.
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.
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.
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.
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.
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?
In this week’s Science Friday, we hit on the concept of hyperstability, which occurs when catch rates remain high even as fish populations decline.
This Science Friday we have the final part of a three-part series on steelhead in the Great Lakes. This is the second-half of last month’s article, authored by Brian Morrison, Fred Dobbs, and Chris Atkinson. The article was originally published in The Osprey in September 2010 (link to the original article in The Osprey is here: http://ospreysteelhead.org/archives/TheOspreyIssue67.pdf). The Osprey has …
