I’m thinking that maybe the SMB just aged out? It’s been close to 10 years since we stocked them. I’ve added a lot of YP over the years, but haven’t added any SMB. We were catching a few smaller ones, so I thought I was getting some reproduction. Now I’m not so sure. This pic is from 3 1/2 years ago. Better days.
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.
