There are many different colorful trout that one could catch.
One rare strain is the Palominos. Bright yellow with some red in the middle, these fish are amazing. Palomino trout are a color variation of the Rainbow trout and are the result of the crossing of a Golden Rainbow trout and a Rainbow trout. The Golden Rainbow originated from a single rainbow trout that was spawned in West Virginia.
Now we have the first document Blue Bow Trout. These are bred just like Palominos, but isolate different pigment. Hopefully we see more of these fish in the future!
