- To understand this video concentrate on the shiny female Dolly Varden on the right.
- She goes on her side and starts to dig a nest.
- A colorful male Dolly Varden comes up beside her, vibrates, and then leaves.
- Partly out of the video on the right a jack coho salmon and cutthroat trout come up on either side of the female Dolly Varden and vibrate in hopes of getting her to spawn.
- The question: Why would a different species such as coho salmon and cutthroat trout try to stimulate a Dolly Varden to spawn?
- Note that cutthroat trout are spring spawners. This happened on September 24, 2014 in Steep Creek, Juneau, Alaska.
