Well, the fact that we were still seeing clouds and clouds of FHM right up until the pond iced over, means that they were not being targeted by predators. Which means to me that no predators were present. Hard to put into words how much this bothers me. I've wasted a lot of time and money. My thoughts are now to just go to a BG and LMB stocking plan. Just like 99% of the rest of the ponds in Missouri. I can buy the fish a few miles from the pond, put them in myself, and know they are healthy.
12 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs) I think that's about all I should put in my little pond. Otter attack in 2023.
