Since we are still waiting on the experts, I'll throw out my opinion.
You're catching fish, so that is a good thing. Too soon to say much more than that. It will take a year or so to figure out where you are at, unless to do an electo survey. My guess would be to start keeping 30-40# LMB/year if the previous owners didn't manage the pond.
Also lot of info under the managing fish forum.
