This would be easy experiment since GFC and AM both Purina products. I woudl be willing to tie up 3 of my 4 ponds to test it out for a season. I would also like to see several brands tested. You can not tell what is in the feed from reading a bag so only real way to tell is fish growth. This would take into account paltaibility digestibility protein lipid content etc etc. So anyone got about 20 small ponds they are willing to stok bluegill for one season and see what happens, \:\)
