Over-harvesting is a good point. I honestly hadn't considered it too much for bass (even though some few keep them), but I guess catching & keeping their food sources has an effect on their size & population also.
I don't use graphs but I do love my baitcasters and fancy lures and can't imagine knowing half the stuff I know without the internet.
Does anyone know anything about wildlife management? I see stuff about it all the time on KY Afield, an outdoors TV program here in KY, and I always think to myself "should this stocking and shocking etc really be necessary?" For those lakes with great fish populations and little pressure in Canada, Minnesota, and Wisconsin, do we know if they are managed by the government at all? I used to swim in the lake by our family lake house and look up at the trees and think "this must look just like it did hundreds of years ago" only to realize later in life the lake was "created" in 1969. Kind of took some of the mysterious wonder out of it for me.
