I tell folks that I want to keep my fish dumb and not become "line smart" and my family is the only people that is permited to educate them. My pond remained drained for 20 years because I had lost total control of the fishing. Operating a retail business and owning a fish pond is incompatible and once you give an individual permission to fish they always seem to bring a friend and your permission is bestowed upon them in perpetuity. I have yet to arrive at a satisfactory solution to manage the harvesting of the fish in my pond. Just prior to retiring, I renovated, filled and stocked my three and a half acre pond along with fencing and gate.
