Even with the addition of an automated feeder to the pond, would tilapia stocked at a lower density (5-10 lbs per acre) be an efficient way to maximize available forage for green sunfish? Also, since any fish over three inches long is out of the mouth gape range of the all but the largest green sunfish, could tilapia cause biomass issues in the pond? One of my concerns if that even though tilapia are tolerant of lower DO levels, my other fish could be put in jeopardy due to more pounds of fish in the water and, consequently, more oxygen being used up.
