WOW you have alot of fish in a little one acre pond. 100 ribbons is allot of ribbons. We stocked 400 YP and only get at the most 20 ribbons that we see. I keep the plankton booming in our pond and can only see 12"-20" in the spring as the water warms up. When it hits 55+ it is basically 15"s of visibility all year till first ice.
I know. Live and learn. I probably would not have put so many in, had I spent a bit more time on this forum before stocking. There was a issue with survival rates on the initial stocking, so I believe I have a fraction of the original 1500 stocked. I did see a lot of ribbons though. Now that I know the GSH eat the YP fry, I'm thinking I do not get all that many through the first few weeks. I have not caught one, very small YP. Yet I have harvested at least 200 adult YP in the last 12 months.
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.
