That very nice bluegill in my experience would have been a bigger fish(BG) if using higher protein food. No easy, simple convenient way to measure the excess food / manure waste and excess plant growing nutrients when using original 32% protein vs higher 40%+ protein feed. Not enough good practical research has been published on this topic.
My associate at a high quality indoor fish growing facility operated with pure oxygen says he sees less fish manure, measurably better water quality, healthier fish, fewer fish deaths, and better resulting fish growth when using the best quality fish food that he can find. End cost for him in the end is better with better quality feed. Over the last few years he has used various fish food brands in his indoor facility. The current brand he uses is 48%protein 18% fat as his larger finish size pellet and this produces the best results from numerous comparisons and "out the door profit and results". This food brand can produce 14" walleye at one year old. No doubt in my mind that BG in the above picture could have been grown with best methods in just 2.5 years or less with better high quality food. In the end it is all about ones GOALS for the fishery.
