I've been reading everything I can get my hands on about bluegill "biology".

Through my obsevations in the field and what I've read, I'm convinced that the two major factors involved in creating trophy 'gills is 'balance' with predators (read that largemouth bass)and a strong population of large male bluegill.

I know Rick Z. and probably others have some views on this. I'd be interested in any scientific or anecdotal evidence any of you could offer.

Rick, in the past you have alluded to the theory that there are two strains of bluegills. Are you speaking of 'cuckolders' and their offspring?

I've been following the studies in IL and MN and am aware of those in Nebraska and SD (though I haven't found much about them) I'd be interested in any information on other studies.
