Chris, This is one of those "it depends" moments, when will you plan to stock the other fish? How long will it take to fill up the pond with water? I'd say go buy 2-3 pounds for now and hold off for as long as you can wait to stock your pan fish, then wait even longer to stock your bass. Bring lots of scrap pvc pipe, scrap boards, drywall screws and cordless screwgun. Look for the baitfish and forage section, find the thread "pvc pipe" and read to see what structure should look like. Add any rock/rubble, stick piles, and larger logs and stumps. IMHO you should not put more than 30-40% of this. I have half of my pond with and the other side has no structure of any kind in it. Thats designated as swimming area. Make sure you put piles at different depts, keep it simple and dont spend big bucks. Fish cant tell if it was free or full price.
