snrub, something that can help you get an objective look at what to keep and what to release might be to keep details length, species, and weight (or wr) on the fish you catch. I use a spread sheet to track all that (and a few other things) so I can keep an eye on what my population looks like. My second biggest fear (after a dam blowout) is having a pond full of stunted fish. I cull small bass like crazy in this lake where I focus on l, they were stocked 5 years ago. Your stocking is a few years newer than mine, but it is never too early to keep records
Another option that may be useful later is to have an electro shock survey done to get an idea of your fishy population. Then you can move on to what you need to do to reach the goals you have set.
All that being said, enjoy the pond, enjoy sharing it with others, and enjoy eating those tasty fillets. People on this forum have proved that what was previously though unlikely or even impossible, can be done!
