Unless you're selling a quarter of a million bluegill every year I don't think that you will run out any time soon LOL.
I would be certain to do a few things first.
Number one, is I would draw the pond down and nuke it. There isn't much in this world that bothers me more than when people get a shipment of bluegill fry and end up with green sunfish in their pond. I hear about it happening all the time and if you nuke the pond you will be sure to have a fresh start.
Also, look at every bluegill by hand before stocking them. Its only 175 fish and you will be able to sort out any nonsense before it can become problematic.
Also, in a year's time, when the pond is chock full of bluegill...I would add ONE female largemouth bass to the pond. I mean, why not? LOL. She won't put a dent in your bluegill population, but won't it be cool to have an eight pound largemouth to stock in someone's pond?
