ewest, it's really great that you're willing to take the time to research something for the benefit of others. I know you've been thanked many times but I would like to add my thanks to the list.
I'm glad that GSF are similar to BG in this aspect, not because that makes it any easier to manage, but because there's so much information about raising BG.
My pond will be small so seining might work for population control. Maybe I should keep the contour simple and without too much structure. What about removable structure? The maximum depth will probably be less than 6 feet. Also in a normal weather pattern I could lower the pond significantly and expect it to fill pretty quickly.
I did find research that said GSF commonly eat small LMB, fry and eggs. Maybe they would put pressure on their own fry as well. Is cannibalism a large factor in managing any other species? Would it make sense to stop feeding pellets after a spawn to encourage adults to eat the fry?
