Well put Norm. Each pond boss needs to decide the best way for them to spend thier funds. This is ofcourse a personal and unique decision. If someone is happy with spending the money on put and take let them do it, it is probably the most reliable way to manage a fishery.
There is a pond here in duluth,mn that is owned by the city. It has black nose dace, suckers and probably a few small brookies. Each spring the MN dnr stocks 500 10" brook trout in chester bowl. I heard that each fish cost over $10. Several thousand other 10" trout are stocked in other small ponds and streams in duluth parks to offer city kids a chance to catch keeper fish. This is a substantial investment for the very temporary but huge increase in catchable fish. But it fits the budget and managment goals of the MN dnr so they keep doing it year after year.
