I was told by Michigan DNR biologist (or I think it was) that for every acre
of water, it can support 50 1-pound bass, 25 2-pound bass, 12 4-pound bass,
etc., as long as there is adequate food (in our case 1000 bluegill per acre,
1000 perch per acre, 25 catfish for cleaning, (again I think it was) 200
gallons of shad. An incoming and out going water sources, or aerator system
(we used a water fountain, and have a good fresh incoming and outgoing water
source - spillway dam). Adequate cover (weeds, brush, trees, etc.) and
structure - that is in Michigan and Northern States in general, that fish
need at least one area of a pond that is deeper than 15-feet, to help them
survive the cold winter. We created a 1/2 acre 20-foot hole for this
purpose.
