Doesn't sound stunted to me either, sounds more like too much predation.

Adolescent bluegills will sex out earlier when there are no big bluegills to compare themselves to. They also pretty much quit growing once they sex out, too. When the bulls are present the adolescents keep growing until they compare to the largest fish and so sex out later; so no matter how you cut it bull gills require enough life expectancy to grow out to the larger sizes. Whether from human harvest or too much natural predation, if they can't live long enough there will never be enough big bluegills to measure against nor the life expectancy necessary to grow that big.

(It can take 8-10 years in the north country to grow a 1 pound bluegill, less of course in milder areas like Nebraska.)

I would say at least the wipers are too much for the 100 acres, if you also want big bluegills. Lots of smaller bluegills would be a very good forage source for healthy wipers though. The wipers being sterile hybrids can be controlled simply by stocking levels. FWIW when predation and harvest are curtailed you will find bluegills moving up in size toward what Lake B shows with a different predation pattern, and that is more likely to be a more natural size structure for bluegills that get enough life expectancy.
