As goes the habitat, so goes what lives in it. The fishery will become a consequence of what I call "Happy Water" and the best habitat. Your mission is to create habitat for the different sizes of the different species of fish you plan to manage. If you know what each species of fish need at their different life stages, you can mimic as much as that as possible. That's what everyone's advice above is basically telling you.

Even better news about your pond? If you get a few years down the road and you don't like where it's going, you can make major changes to fix it in one day. That's one of my favorite things about small ponds.
