I have ribbons! Unlike last year's unfertilized eggs, the ribbons are quite a bit smaller and scattered on submerged plants, rather than on branches. Instead of 2 or 3 like last year, I have dozens (deposited in the last 2 days). I am guessing these are from the 100 small YP stocked last year, rather than the much larger 25 fish stocked 2 years ago (based on ribbon size and number). Hopefully, these will be fertile.
