Jason - Was out of town for several days. You can stop by anytime; it is best to call first to make sure that I am here and not out somewhere getting wet in somebody's pond.
The bigger the pond the more fish you will be able to grow. Obviously you will be able to grow more minnows in the 20x20 area. Depending on conditions and, if optimun ALL the time, you can grow up to approx. 2000 lbs per acre ( naturally fertile, unfertilized ponds grow about 250-300 lbs of fish/ac). 20'x20' is 400sqft = 0.009 ac = 18 lbs of fatheads.
18 lbs of fatheads at even best conditions will produce 1.8 lbs of bass weight.
