I was a bit off in my above post. In WI a person can only use the fish on the same lake if you added water from that lake. You can still take the fish home in less than 2 gallons of water but if lake water was added you can only use them on the lake the water was added from.
Minnows and other Bait Fish Regulations
You may take live minnows purchased from a Wisconsin bait dealer (which includes Wisconsin registered fish farms) away from a waterbody if any of the following three conditions are met:
• Anglers can take purchased minnows away from a lake or river and use them again on that same waterbody.
• Anglers can also take purchased minnows away from a waterbody and use them elsewhere if no lake or river water or other fish were added to the bait container.
• Anglers can also take purchased minnows away from a waterbody for use elsewhere if they intend to preserve them as dead bait using approved methods.
