Have you set out a minnow trap to see what species of "minnow" you're seeing? If your Anderson fry did this well, you'd have a real rarity on your hand. It seems from other people's past experiences, stocking fry into a pond full of hungry bass rarely produces a viable population of golden shiners. Perhaps with all the wooded cover and such, your fry were able to find cover and you had a good plankton bloom to increase their growth and survival rates... If you haven't set a minnow trap out, give it a try... You can buy one for less than $10 and it'll be worth the money. The shiners you catch, if you do catch some can then be used for bait to do more "creel surveys"... Keep us posted! This is very interesting...
