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.
It has been a tough stretch for wild winter steelhead on the West End of Washington’s Olympic Peninsula. Now, several months into the season, some of these runs appear to be even weaker than forecast. Given the alarmingly low returns of coastal wild winter steelhead so far this year, it’s not a surprise WDFW had to take additional action to protect these fish.
Our Science Director, John McMillan, shares some early findings from our snorkel surveys of the Elwha River’s summer steelhead this past year.
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.
Last week, the Washington Department of Fish and Wildlife (WDFW) enacted new regulations coast-wide with the stated goal of reducing our encounter rates on these last, best wild runs here in Washington. This includes some serious changes to the way we fish for steelhead.
The Lower Elwha Klallam Tribe has completed a two-year restoration project of Little River recently, making it more salmon and steelhead friendly. We go in-depth with this part of the tribe’s Elwha River watershed restoration work.
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.
This week’s Science Friday is an update on a topic we have covered before: the effect of the Hood Canal bridge on survival of steelhead smolts passing through Hood Canal.
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.
