A couple of thoughts:
First, what do you enjoy? You and only you can define your goals.
Second, you have a pretty complicated mixture. Just on the surface, the crappie, hybrid rockfish (?), etc. aren't that desirable. The fact that you catch fish without trying sounds like underfed due to lack of forage or a never fished pond with ignorant fish.
I believe I might get a pro to do an analysis. It might be prudent to rotenone and start over.
Keep your checkbook handy.
