Just an FYI, NeMo fish hatcheries in Perry MO used to stock YP, I�m not sure how the fish are. I bought FHM from them, and they did very well. I also bought HBG from them, and they�ve done well, except reproducing way more than I thought they would. I bought my YP from Rainman here on the forum. I believe he got them from South Dakota, but not sure. They�ve done very well.
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.
