All of the much appreciated help has cause me to have two additional questions. #1 What difference does fertilization make? Are you fertilizing the plants so the little feeder fish have something to eat? #2 Would it make ANY sense at all to have one pond with Crappie as the only predator, and the other two ponds with the common combination of Blue Gill, Catfish and Largemouth Bass. P. S. I was told that Smallmouth Bass will not make it in our Texas heat. Thanks again for all of the help, Marty
