Here's a cool article from the Montana Department of Fish Wildlife and Parks about its 1974 decision to stop stocking trout in streams.
It bordered on heresy at the time, but proof of its success is nearly unargued. The state attracts trout anglers from all over the world and boasts not just a few hot fishing destinations, but a whole state full of rivers with healthy populations of wild trout.
There's a lesson there, no doubt, especially in state's like Idaho where millions are spent to stock trout in rivers during a time of tight budgets
Here's an excerpt from an article and Q&A about Montana's historic decision. You can read the whole thing in a link below.

Without stocking, many Montanans asked, what would happen to the state’s famous trout waters and the businesses that relied on legions of anglers arriving from across the country each summer?
