Wow... I had not really thought this through. Reading the older post in this thread was eye opening.
4" BG there are 144-181 in 8 to 10 lbs.
5" BG there 72 to 90 in 8 to 10 lbs.

To make is easy, let's just say 100 BG required per yr for one Bass. I put 25 HSB (2-4") in the 1 Acre pond in Nov 2015 with 25 LMB (2-4"). That's at least 5000 BG required per year not taking into account LMB spawning.

I had 750 BG and 100 RES with a bunch of Fatheads to start with. By mid summer 2016 you couldn't find a fathead. Two weeks ago I hooked my first HSB and it broke my line close to the bank (light tackle but what fun). I'm hoping it was at least 2 lbs.

I'm now intrigued by the thought of adding Tilapia to maybe allow some growth of the BG.
