With all the talk about C&R vs. C&K, I started thinking about the epidemic of Whirling Disease that happened in Montana rivers, oftentimes, almost completely wiping out a trout river. C&R was blamed as the primary reason for spreading this disease. I am cuious, is it possible for something like this to happen to steelhead? After all, a steelhead is a rainbow trout that goes out to the ocean. Is Whirling Disease something we should be worried about here?
