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.
This is a topic we have discussed several times in the past, but given the critical nature of cold water refugia, and as the warming climate makes the warmest time of year even hotter, it’s a good time to review what we know about these crucially important habitats.
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.
