How Many Types of Trout in this Photo ?

It has been a hodge podge of genetics since the first hatchery trout were produced at the Baird Station Hatchery on the McCloud River in the 1880s, those pioneers of trout stocking had no idea that it mattered if you mixed subspecies, coastals with redbands and goldens were all just trout to them. They did a lot of mixing and by 1900 had shipped mixed genetics all over the world. It's also said that the rainbow genes in any given group might be expressed in multitudes of ways depending on environment.   More important is that many fish change color as the water and food supply changes throughout the year and any one of those dead trout would have a totally different appearance by next January.
