Shan, My thought about adding fatheads to an existing pond: They are very prolific and provide protien to smaller bass, bluegills, etc. I have a 1/4 acre (in good times) pond that I have bluegills and fatheads in. I seine a couple of times a year to provide food for mine and a neighbors pond. My only concern is adding to the overall biomass.

Am I kidding myself about helping the smaller parts of the food chain to ultimately help the larger predators or should I shoot for a self sustaining body of water? Understand that after 2 DO crashes, I no longer fertilize.
