Leo, pretty much the same in Michigan. If the pond has a permanent inflow or outflow, even if the outflow goes across a pasture to a culvert, they will not allow stocking of Tilapia.

With that said, I FINALLY received my license today in the mail, so I can start applying for pre-importation permits to stock fish in Michigan. It was a LONG road!!!!
