I'm in favor of small mouths. Island lake north of Smoky lake was stocked years ago. No reports of them in there now but I saw some come out of there a few years after it was stocked. So they can survive, for at least a few years. I would bet there are still some in there today. Think the locals are keeping it quiet. I think they should stock Hastings lake with them. What harm could happen there?
All the shrimp get eaten.
