I've been meaning to try fishing w/ crawfish (I've read people using them here, and heard they're really good for spring bass fishing). I was wondering if I caught them in my local lake and used them in another, if that could spred something or if it's unacceptable for any reason? Do bait shops do something to them to know they're safe? This may sound like a dumb question. I always wash my waders before going to differant places, and I just don't want to do anything that could be damaging. I live in estes park, and don't know of a bait shop anywhere close or I would have asked them. Some people on this site have talked about catching them and saving them for later fishing days, and never said if they were going back where they caught them to fish. ??? Sorry again if this is a dumb question.
