Thanks . Some observations.

The LMB look in good shape and of various sizes. The small ones were probably eaten by the larger ones, stuck in the muck or went out the drain.

The lbs of LMB + CC are within the high normal range for predator carrying capacity for an unfertilized and un-fed pond your size (35 to 75 lbs). They would be close being normal for a fertilized pond ( 80 to 150 lbs).

8 lbs is large for a northern LMB. If you had no Fla LMB genetics and your neighbors did - that would explain the difference.

It does sound like your populations were a little out of balance (limited large BG).

Did you check the exit of the siphon for fish ?

WRT a stocking plan for your stated goals keep in mind that at 200% of normal carrying capacity you would have around 200 lbs of LMB. A high % of those will not bite a lure especially the big ones. On small ponds the catch rate for LMB should be considered.

For a LMB pond the more current stocking plans are much different than the standard plan which was established in the 1950s (Theo provided those). Most current advice is 10 lbs of FH per acre , 2000 BG/RES per acre and 75 LMB per acre (100 for a balanced pond and 50 for a trophy LMB pond)with the BG and LMB at 2 inch stocker size. BG and FH in summer or fall of year 1 and LMB in spring or summer year 2 ( 9 mths +- apart).

Lets see what others have to add. Guys your turn.
