An Attempt to Breed Better Biters Has an Unexpected Twist With Implications for Broodstock Collection

In Science Friday by John McMillan

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.

Update: Emergency closure for some winter steelhead rivers and the Quileute Tribe’s perspective

In Washington by John McMillan

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.

Science Friday: Juvenile steelhead finding refuge in tributary mouths

In Science Friday by John McMillan

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.
