Are you talking about manual hand spawning?
If so it's really simple. There's the dry method and the wet method.
If this is what you're asking about I can easily explain in here.
But a lot of rainbow trout farms no long bother. They buy eyed eggs from a farm that specializes in producing them. No need to keep brood stock around and handle fish in frigid water.
