What fish are in them now? What I would do is get some bluegill and a few bass. 5-1 gills and what ever you do is stay away from crappie. A couple of albino catfish "2" in each pond will help clean up crap. Just remember as those albino grow they will eat your spring spawn quickly.

I have a half dozen of the albinos in a 3 acre pond and last year we caught one that was OVER 48" and he/she was less than 10 years old.......needs to eat alot.

Use IDNR as a resource as they are very good at helping people with ponds.

Finally........ you need to fertilize a pond like a food plot........the fish are eating plant life from the pond. Best thing I do is put lime on the pond!
