Dense, shallow cover is a great start and you've already seen some results. If you have a dock you can pull umbrella nets around the edges and collect thousands of BG fry weekly with minimal effort. Cage them with small mesh [1/8"] and feed them daily. Add a few crayfish to each cage to help with the filamentous algae growth, they'll climb up and down the cage and keep it clean in my experience and you'll only lose occasional BG to them. Cages cost less than $50 and 1-2 hours of labor and you could easily raise 500 BG or more per 3x4' cage and release at year end. You have a free source of YOY BG and with periodic feeding can grow to 3-4" easily by end of season for release.
