How do I know the number of fish I should be taking out over the summer to keep my balance in check? (I know, impossible question)

I only have BGs and LMB. One acre pond, put in 200 BGs in '07 and two dozen LMBs in '08. My main goal for my pond is to have decent sized of both, strictly for friends and their kids to have a little weekend fun. I just want to be sure my numbers aren't going to high and causing small fish and heavy bio load on my little pond. Is there a guide (probably by weight?) to know when/how many fish need to be removed before it gets too far?

Just looking for a generalzation based on size of my pond, amount of fish I put in, etc... like "you should be eatin' at least a dozen bass a month, and twice that many bream".

Thanks!
Jeff-

1 acre pond, slopes to 15ft depth. Has BG and few LMB plus a half dozen pesky sliders.
