Wild Steelheaders United was established to educate and mobilize wild steelhead advocates to help restore and protect wild steelhead populations across their native range in North America. Our formula for success is based on bringing people, businesses and communities together to advocate for improved science, habitat, policy and fishery management so that future generations will have healthy, fishable, harvestable wild …
Lessons from a steelhead rescue and captive rearing program on California’s Carmel River
By: Natalie Stauffer-Olsen, Staff Scientist, TU’s California Science Program One of the things that I have always admired most about O. mykiss is how adaptable and resilient they are. The rainbow trout, in both its resident and anadromous forms, evolved to take advantage of the most abundant habitats for their different life history stages as well as the genetic …
Not too hot, not too cold, the ocean must be just right
Two weeks ago we were on the Dean. This week we go even further north, to Auke Bay near Juneau, Alaska, for our next Science Friday post. The greater Juneau are is home to several rivers that host wild steelhead runs. Auke Creek is perhaps the most important of these feeder streams, as scientists at the Auke Bay Marine …
Science Friday: Surviving heat, drought and ponded streams
It is that time of year again. Heat wave after heat wave. As summer progresses stream flows will continue to decline all across steelhead country, and in some cases, smaller tributaries will go dry. In other cases, streams won’t be completely dewatered; instead, they will become ponded. This occurs when flows diminish so much that the only remaining surface …
Science Friday: Certain genetic families survive better in hatcheries and might help explain why hatchery steelhead do poorly in nature
Spring is here and we’ve got a real shot of warm weather on the West Coast. Certainly, spawning steelhead appreciate the ecological effects of this boost in thermal energy. Last week we reviewed a recent paper on repeat spawning in steelhead in the Hood River, Oregon. This week, we return to the Hood to look at another paper out …
Science Friday: Juvenile Density, Distribution and Habitat Capacity
By John McMillan New Year, new Science Friday! Last week we looked at the concept of carrying capacity, how it is estimated, and the most important habitat factors used to come up with those estimations. This week we shift gears a bit and review studies that illuminate how patterns in fish distribution can affect assumptions about carrying capacity. Recall …
2017 – a Bad Year or Part of a Trend?
Ocean conditions are vitally important for wild steelhead runs — probably every steelhead angler knows this. But what does that phrase really mean? The ocean is a massive and incredibly complex system, and there are many factors out in the big blue that can influence steelhead in any given year. That is why it is so difficult to parse out …
