If you absolutely interested in LMB and cannot find single sex fish, I would absolutely get pellet trained LMB. With pellet trained LMB, this is my opinion of the number and combo for your quarter acre pond and stocking timing...
This early spring, stock FHM as soon as is feasible and they are available. Not too much after ice out and they should be capable of stocking. 2 lbs of FHM will get you off to a great start...
I'd wait until the late spring to early summer(June or so, when the water hasn't warmed up too much) when I would stock the HBG at 100-200 depending on just how many fish you plan to harvest to eat and if you want to stock them annually or every other year. Less if you are stocking them every year and more if you plan to eat more... 2"-3" fish should be a good size.
I would also stock the RES at the same time as the HBG. 50 fish should be a good number to get your off to a healthy start, again fish in the 2"-3" range would work well.
The following late summer to early fall(Sept or so) I'd stock 20 pellet trained LMB. You should be able to find them in the 4" range but larger ones up to 8" would work. At that size, they shouldn't be big enough to eat your HBG or RES as they should have put on a good bit of size through the summer growing months.
I would also stock 10-15 HSB with the LMB if you are interested in an added option to your pond. These fish will not reproduce and will need to be restocked every now and then, yearly, every other year or so... Even less numbers, say 10 or less if you plan to stock annually.
If you really want CC in your pond, I'd keep the stocking numbers low, around 10 and no more than 20. Do not allow them to grow huge. Harvest them when they reach no more than 18". After about that size they really can start to hog feed and cause problems.
This stocking plan is jut my opinion. Let's see what others have to say...
