"That all fish, frogs and other aquatic life in privately-owned ponds are, and shall remain, the private property of the owner or owners of such privately-owned ponds, and that such fish, frogs and other aquatic life in such privately-owned ponds may be caught, taken or killed by such owner or owners at any time."
Well that seems to answer my original question. Since the frog came from my pond, according to this then it is my property.
From what I've read so far it just says, "wild animals, wild birds, both migratory and resident, and all fish, amphibians, and all forms of aquatic life." I haven't seen anything at all about reptiles. Lot of stuff about hunting in there. It's all very confusing to me.
But like I said, I bought four out of five of my snakes from pet shops. So how is it illegal for me to have bought them but not for them to have sold them to me in the first place? Anyone can go in and buy any animal in the store. No questions asked. I didn't just buy from one store either.
