You stated any season. I can take shovelnose sturgeon being a MN resident. Boarder water is still have MN. Give it time and the catch and release season will grow. Even possibly have a keep season like the boarder waters.Gorak, there is no open season on Shovelnose sturgeons in inland lakes/rivers, only border rivers. The only way you can keep them legally would be buy a captive bred sturgeon. There is a law for taking natives for home aquariums and sturgeons isn't on the list.
That law is indicating in water. The only way you can transport them in water for aquariums is that list and with kids.
If they are not in water when I transport them for my personal use, then I am legal. If they survive the trip there is no law that says they can't be place in an aquarium.
