My two big issues with gigging are length of season and lack of enforcement. If enforcement were better, then I would have no issue with the length of the season. There's no doubt in my mind that what happened in Ripley County also takes place on other Ozark rivers and could be largely curtailed with better enforcement and harsher penalties. Anyone who has fished much in the fall or winter has undoubtly caught smallmouth and other game fish with gig marks or open wounds on them as a result of being stuck and shaken off of a gig.
The problem I see with limiting gigging on trophy smallmouth water are the length of them. Generally speaking the trophy smallmouth areas tend to be longer in length than the trophy trout areas. Take Big River for example. The trophy smallmouth area pretty much extends the entire river. Though fine by me, if that were to happen it would limit the area that a person could gig to basically a couple of small sections of river around and upstream from Leadwood.
Also, not trying to pick a fight or argue but accidentally sticking a game fish is no different than someone shooting a spike buck thinking it was a doe. Though both happen, neither are acceptable. One of the ten commandments of firearms/hunter safety is positively identifying your target. That should apply to gigging as well.
