Check out this video of rainbow trout spawning in Cow Creek.
Along with the video came this field dispatch:
You can see some smaller fish darting in and out around the female on the nest at 3:48, and again around the last 2 mins. I couldn’t figure out what exactly the smaller fish were doing if they were trying to get in and feed on the eggs, or fertilize the redd or what….
Highlights: redd making at 5:28, 6:32, and 7:43.
I have a few other videos of the other pairs I saw. 4 pairs total with some other males hanging around all in about 100m at the bottom of the grade. I see them in here every year but never this many and never this big.
The video runs a little over ten minutes.
