You may be right about the NH stuff. I may have read it wrong, but I think they don't allow ice fishing for salmon.
The VT info I heard from the state. The lakes where stocking was eliminated had at least 90% wild populations. There are other lakes up there that are still going to be stocked that are 70% to 90% wild. Check for fin clips in Crystal, Wiloughby, Seymour..... That will tell you the origin.
