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: How summer steelhead are genetically different than winters
Many anglers over the years have no doubt wondered why some steelhead return to freshwater during the hottest and driest part of the year. The reasons why are both simple and complex. The most obvious difference between summer steelhead and their winter run brethren is that they enter freshwater streams in summer and fall, not winter. Duh. But that …
