I have a pond similar to yours - I based my stocking off your threads - 1/10 acre, SMB, YP, GS,FH. I have not seen YP ribbons on the shallow structure, but I have seen schools of yoy swimming around. I think they are using two big pine trees that I sunk in the deepest part of the pond ~25'.

I have not tried Tilapia yet, but if I can find a supplier I will try them this year. Check out the Stocking Tilapia - please weigh in thread. Sounds like even with a short growing season there is chance at a couple good spawns. They grow rapidly and spawn at ~4" -See Page 4 of thread.

Not sure where you would get them in NY, I am still looking for a place in MI.
