I got my YP from Laggis fish farm which was just over an hour drive from me. That is not a large operation and he gets his fish from suppliers I think in Ohio or Indiana so he can't always fill orders either. It would be a long drive for you but probably cheaper than shipping and you could get larger size YP. How many were you hoping for?

Otherwise you can try Stony Creek near Grant MI as they often have a selection.

I am not familiar with it but there is a fish farm in Imlay City as well. That might be closer to you.

Wow, I might need to create some forage ponds in my back field and try to get a reproducing group of panfish, FHM, shiners, and maybe even YP to help fellow MI pond owners out. I'm not sure I would be allowed to sell them without license and fish testing but maybe I would donate them with hopes for a 'tip' from the customer.
