There used to be a really interesting documentary on Amazon prime called The Frozen Chosen. Lake Winnebago, Wisconsin has a legal sturgeon season. It's only lasts 16 days on the ice and you have to sight fish and spear them for it to be legal. I recommend checking it out if you can find it.
That's a pretty accurate documentary. Poygan is an upriver lake in the Winnebago "chain" and spearing is the "event" on the ice and at the weigh stations and taverns around the area during the season. There used to be a radio broadcast with Polka Music (Jerry Schneider I believe) featuring updates and interviews from people around the lakes. Its a wonderful cultural event. Water clarity is a significant factor in the success rate. Spear fishers hang "decoys" of all shapes and sizes down the hole...primarily to guage the size of anything swimming by. There's even been a bit of drama the last few years...they busted a black market caviar ring. Caviar was being purchased in WI and sent to fancy eateries in Chicago...allegedly.
A few years ago, it was made clear in the angler's guide that one should not target lake sturgeon. That clause is no longer in the more recent annual guides. Instead, sturgeon has been listed as having a possession limit of 0.I believe it is now legal to target sturgeons then release them.
