If it's white growths it's most likely a fungus that occurs while spawning. When the fish spar in preparation for mating they incur sores that tend to get fungus on them when they are in high densities and under certain conditions. When I lived in Utah, there were entire age classes of browns that this happened to on the Provo and it is a yearly problem. It was thought that extra catching/handling of the fish while they are spawning can make it worse through slime removal.
When I was at the South Fork a few weeks ago, I sat down and watched a group of browns on redds and noticed a couple that had some fungus spots on them but none that looked terminal.
