I visited the trout/salmon hatchery near Oakridge, Oregon. Amongst many thousand steelheads there was one fish definitely blue colored.
The hatchery worker didn't seem impressed, he said it happens. He was more interested in the albinos they see from time to time.

In 2005, I saw a blue-shaded Rainbow Trout in Bright Angel Creek inside the Grand Canyon. It was one of 200 Rainbows seen. The USFWS person said it wasn't that odd.

Rainbow trout produced by a hatchery in Missouri regularly includes small (<0.1%) numbers of blue individuals. Efforts were made to fix a blue line but such individuals appear to be sterile and efforts ceased. Blue color appears to be recessive and may require more than one set of genes to interact to get the blue color. Their system of breeding and mixing broods makes it difficult to spot fish that throw blue offspring. In my opinion the blue fish are less vigerous than even albino / "golden" trout (not same as golden subspecies) which would be a reason not to produce them.
