I thing truely the blue and flathead catfish are a more efficent preditor than the bass. I think this because the catfish can hunt in water that is muddy as coffee and still grow and stay healthy. Bass on the other hand have to have stained water or better to hunt well or they begin to loss weight and get stunted. Bass in clear water may can out hunt a blue cat but there is no way a bass can out hunt a flathead in any water clarity.
