Ok, time to revisit after a year has gone by.
April of 2022, I added 150 2.5" to 3" Copper nose blue gill and 150 2.5"-3" Redear sunfish.
April of 2022, I added 5 bass from a local lake. 4#,3#, 3#, #2 and #2.
October of 2022, I added 100 2"-3" native bass and 100 2"-3" Hybrid specklebelly.
April of 2023, I added 10 bass from a local lake. Two in the 5# range, two in the 3# range and the rest 2-3#s

I have caught a ton of bull head that have been removed.
I have caught various sizes of channel cats. 3" to 22"
I have caught bass but feel like they are the ones I put in there. Still nothing smaller than 16"
Various other bluegill/sunfish that I'm not sure of.
A couple Green Sunfish. Why are they bad for a pond?

My questions are:

Have I messed anything up? What should I have done.
I now see a ton of 3 in catfish eating the floating food. I didn't see this last year. Why?
How should I proceed with stocking?
How long until the 3" bass I stocked in October be big enough to catch?
