JEC :

Welcome to the PB forum. Good first post. It sounds almost like a college fisheries science test question. First when was the recent stocking mentioned in para. one? What are MM (mud minnows)? Were all these recent fish small fingerlings? What is the background of the "Fish Farm Guy" ? Has an assessment been done by seine , cage/trap ,or other ? What are your goals for the pond? What was the status just before you put in the recent fish? What size LMB are feeding in shallow water as described? Time of year for the RW data?

For example if you had LMB of all sizes and put in 300 3in. CC they may well have been eaten. They are slow easy prey for LMB and their recruitment is minimal in pond with LMB. Another point most all the fish stocked from 96 back are well past their life expct. if still there (probably dead by now). As a result determining past recruitment of the fish and status just prior to the recent stocking is key. Another point if within the last year you stocked the additional BG and water fertility is low those BG could be not getting enough to eat. Some of the info seems contradictory. Example "BG yearling to 9", but I would expect a larger ratio of small BG"- Yet I assume you recently put in small BG. Basing small BG counts on visual info only is risky. BG 3in. or less can be almost invisible. Seining or trapping would give much better data.

With the current info I can't say that I agree with the assessment or plan. In small ponds with LMB and BG in the mix I have never seen or heard of a pond that is balanced and self sustaining. They require population mgt. especially among year classes/sizes. I am not aware of any LMB/BG ponds which are stock , fish and forget ponds that stay balanced and healthy. If there is little fishing and minimal fish cull that is what you have described other than adding fish once in the last 10 years. Using just the basic info provided you have said :

LMB all sizes healthy only a few sm. ones seen
BG all sizes larger ones under weight (as per creel survey)
FC smallish for the species
small minnows ok
CC likely gone

Last but very important are the known fish predators. Of the river otter, osprey, heron, storks, cranes, anhinga two of these can cause considerable harm to a 3 acre pond. Otters and anhinga ( these are often water turkeys or cormorants) are best kept out.

For what it is worth my WAG at this point is near balanced as a result of the recent stocking but not enough food for the large BG , possibly near out of balance predator crowded (FC and LMB) at small end of the food chain. This speaks volumes for the need/benefit of year class info. This is the only way I know to account for out of balance one way at the top end and out of balance the other direction at the bottom (small) end. Post more info if available and we can guess some more.
