Conflicts
A female Sockeye Salmon (Oncorhynchus nerka) pauses over her redd while a male makes a displacement activty dig followed by two competing males. In the background is another female that potentially could attack the female in the foreground.

Female displacement activity
The intrusion of a male Chum Salmon (Oncorhynchus keta), which is being attacked by one of the male Pink Salmon (O. gorbuscha) into the territory of this female Pink Salmon has interrupted redd construction. In frustation, she is making a displacement activity dig upstream of her redd, which in foregound of this image.
