Salmon don't select a single mate. Instead, the female makes a depression in which she lays her eggs. The eggs are then fertilized by one or more males who spread their sperm over the area. Once they have spawned, the salmon will die.
Salmon have a number of peculiar mating rituals. Specifically, salmon will swim for very long distances upstream to reach a particular mating area.
