Jumping from keeping fish in a now fairly regulated harvest system and comparing that to unregulated market hunting or slavery is a big jump. Just don't buy your catastrophe mindset for every species that someone can selectively harvest. If people cannot find longear sunfish they just aren't trying to find them. Gravel mining, bank erosion, cattle in streams, water quality degradation, etc., are far more likely to decimate this species than selective harvest. I won't shame someone on this site for using a legal method to harvest fish for the table. I see no evidence that Huntingducks117 is out there filling trash cans with fish or wantonly wasting these resources.
