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.
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
It hasn't. Natural selection is a key part of the ecosystem itself.
Natural selection is the mechanism primarily responsible for the development of today's biodiversity.
No, natural selection works on that genetic variation presented to it.

Adaptation does not allow for natural selection: natural selection causes adaptation.
The prefix of natural selection is "natural" and the suffix is "-tion".
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.

Farmed salmon are raised in ponds. Wild salmon are caught in their natural environment.
