Maybe you guys already knew about this, but I just saw on the Kentucky Afield show on 6/21 that the KDFWR stocked the upper parts on the Cumberland River with lake sturgeon. I thought it was really interesting, but I can't seem to find much about it anywhere else. The only mention I found of it was from the Wisconsin State Journal (the fertilized eggs came from Wisconsin). Since they take 20 years to reach sexual maturity, they're planning on stocking some of them every year for 20 years, to establish 20 year classes. Pretty ambitious. It'll be interesting to see how it all turns out.
