Jeff, make sure you have YP spawning habitat in the pond. Their egg skeins don't do so well if they are laying on the bottom. They need to be up off the bottom so water can circulate all around them. Then once the eggs hatch, the fry and fingerlings need dense cover to hide in to avoid predation.
Lots of branches and American Pond Weed around the edges. We just see fewer and fewer ribbons every year. I restocked some small YP a few years ago, we are catching a few of them. Not keeping any.
