For unique marking, I was thinking along the line of LMB, PKS, and YP. But whatever species you are interested in tracking. If you catch any LMB between now and ice up, I would especially like to see them marked uniquely.
You have a limited amount of time between now and ice up and it's more important to reduce your standing weight than it is to mark panfish. Don't let marking fish slow you down much. Maybe 5 or 10 of PKS and YP and only if it's not slowing you down. Honestly, for the panfish it can wait until spring. How much time do you have to reach your goal? How much time before ice up? So presently, with your estimate of population, there is about 116 lbs of PKS, YP, and GSH ... 50% of that weight is 58 lbs. Each day you fished and caught 60 fish, you caught around 10 lbs of fish. This catch per unit effort is going to decline as you remove fish so you may not make the full goal before the bite gets slow or your pond starts icing. Just get as much as you can without going over the goal.
For your FHM supplement, I would supplement ... at least ... what you took out (by weight) of panfish. So if you took out 40 lbs of panfish, then supplement at least 40 lbs of FHM. Don't expect high survival of them and hope that all get eaten by spring. It would probably be OK to supplement a little more if you wanted. But I probably would not supplement more than 15 lbs above the weight of panfish that you removed. If I had the choice of size grading, I would chose intermediate sized FHM. The cost is the same, I would want them to be in the 1.5" to 2.25". Wouldn't hurt to have some below those lengths but don't let them push aged adults on you if you have a choice. Smaller FHM have more potential for proportionate gain through the winter. Meaning that, they will provide more additional forage by growing. Also, they will be more inclined to benefit your less than 9" LMB than your two (possibly more) big ones. You are going to lose some FHM to the YP and PKS and to GSF that you were not yet able to remove ... but the LMB will respond to such a supplement, and I do expect that there will be a good boost to size and condition of the LMB that are averaging around 7.5" currently. The most gain (through April 15th) that you could expect would be around .40 lbs each. There is potential for some to reach 10". It will depend on competition for the FHM.
Anyways, good luck and keep us posted.
