Bob, if you're in the area everyday, keep a coffee can full of feed close and feed them small doses as often as possible. If you have an endless supply of food, maybe try 2 coffee cans, and see which one they prefer ! The Bgill/Readear will get very aggressive feeding, and grow fast. I hope you're a country boy and like to fillet & eat perch ! \:\) Otherwise, without predators, you will overpopulate in a hurry !
