How far North are you? LMB do have a northern range...if you're beyond it might be risky to attempt to build a fishery around them. Can you check with local waters and see what panfish [BG, PS] and whether they have SMB or LMB? Would help you make some decisions on what type of fishery to establish.
I'm pretty sure you'd be looking good with a YP, PS and SMB fishery, but you'd need to hammer the PS in order to keep their population in check and sizes optimal.
