What species of "minnows" did you stock? If they are fathead minnows(FHM), they won't last much more than a couple weeks in a bass full of LMB. They do not handle predation well.
I would stock the shiners now rather than later. Give them a chance to pull off a spawn and possibly establish in your pond. 5 pounds may seem like a lot, but in a 2 acre pond with 5 pound bass and CC, most will be gone in short order. Most parts of OK, can support threadfin shad with winter kills only every few years. You may want to look into stocking threadfin shad into your 2 acre pond. It's kinda on the border for minimum size, but depending on fertility, they may work. Which brings up a question, do you fertilize your ponds?
