Overcrowded pond question

[bassmaster1983]

One of the ponds I fish is about 10 acres in size. It is full of bass, but most are about 1 to 2 lbs. I just read that to have a premium bass pond you should eliminate the males. I was just fishing it last saturday and got tired of catching those size fish. What I would like to do is show the owner the article and try to convince him he has a problem. If he is agreeable I would have to know how to tell males from females. I would not want to totally eliminate the males, just put a dent in them. As I would think it would scare the owner into thinking there would be no reproduction. So, without any funny remarks about female fish (i.e. the ones with boobs, or something like that) is there any way to mark the difference between males and females? Thanks.
