I have cleaned both rainbow trout and yellow perch caught from my pond with snails in their stomachs. In neither species of fish were the snail shells broken. If I recall correctly, the innards of the snails had been digested.
Over the years we've been seeing and catching fewer and fewer YP, most likely due to predation by the GSF and LMB that live in the pond. And, anecdotally, the snail numbers have risen. I haven't identified the snail species. There are some with their spiral like a cinnmamon roll; others spiral like a soft ice cream cone.
I have never identified any grubs in the flesh of the fishes I've eaten from the pond-GSF, BG, HBG, LMB, YP, BCP.
My strong desire is to source some pumpkinseeds to stock. But in more than 10 years, I've been unable to locate a source for these beauties.
