I think especially with FFS, something needs to be done. Every guide has one, and once the word gets out about a local little slough or Lake within 45 minutes of DL, they all swarm like buzzards.
I'm constantly flabbergasted by the fixation of perch. To spend money to transfer them from one body to another-- sloughs that were likely stocked with perch in the first place -- especially Devils Lake, just makes me shake my head.
