Dusty,

Removing the large fish doesn't stunt the fishery, unless you are removing the majority of these large fish, and you have large numbers of other fish, and limited food or shelter. There are alot of factors beyond the removal of large fish. That is a big assumption that the large fish aren't being replaced by other slightly smaller fish. Again, it isn't the removal of the fish as much as it is the other characteristics of the pond or lake. The limted or overabundance of other fish and prey items is what will cause the stunting of the population.

My experiences are mostly in the south, and this isn't an issue. I could see this happening on farm ponds, but I don't see it happening these days on any moderate to large body of water.

Perch do the same thing, and are stunted very often due to competition for food resources. Overharvest of black bass at the magnitude needed to achieve what you've described (granted this may be possible in a small pond) isn't occuring.
