Connor you are giving me the itch to get to feeding my GSF better than I have been. After finding out my old pond was infested had GSF, decided to try and make lemonade out of lemons and I also am trying to grow the GSF up to good size. Now I return GSF back to the water that are over 6" and remove any smaller that I catch. Also have a modest feeding in this pond of about 2.5-3# per day and the pond is about an acre.
