Salmon have evolved to live in large groups, and this is their primary defence against predators.
Like most fish, when a shoal of salmon feel threatened they will begin to 'school' meaning: move together as a group. Groups of animals who look the same and closely mirror each other's movements make it very difficult for a predator to identify a single target.
Biologists call this phenomena a 'shell game' in reference to the con-trick of hiding a pea under one of three shells, shuffling the shells and having the mark try to guess which shell the pea is under. Herding animals, such as antelope or Zebra, have evolved the same technique.
How animals achieve this effect is still the subject of study, though a comparison is often made with a 'Mexican Wave' where a large crowd coordinate their actions by copying their nearest neighbour.

they protect themselves by working together to confuse the animal that is wanting to eat them. when this mostly happens it is matting season.
The trout such as the brown trout can't really defend themselves. All they can do is swim for their life. LITERALLY!
Swim away.

The rainbow trout, also known as a steelhead, belongs to the classActinopterygii.
No, rainbow trout will eat insects on the water top, as well as smaller fish.
The scientific name of a Rainbow Trout is Oncorhynchus mykiss.
No, it is not an albino. An albino by definition is a "an animal or plant with a marked deficiency in pigmentation". The fact that these trout have pigment means they are not ablino.What they actually are called is "Palomino Rainbow Trout". The Golden Rainbow Trout originated from a single Rainbow Trout that was spawned in the fall of 1954 in West Virginia. This trout's body color was a chimera of golden and normally pigmented tissue. When this fish was crossed with a normally pigmented Rainbow Trout, the offspring (what we have come to refer to as Palomino Rainbow Trout) were lighter in color.I caught one this past Saturday here in Oklahoma.
No. They are two different fish. They live in closely the same habitats.
