Just as an update, we stocked 24 6"-8" Largemouth bass (a hybrid of Florida & Oswego), into the pond. 4 so far have died of shock, we presume, but the rest seem to be doing fine, as they're already feeding. With the bluegill spawn coming, we figure the bass will have plenty of food to thrive on. I'll keep updating as time goes by. Thanks for all the advice and info!
