I don't think YP are available around mid Missouri.
My pond is loaded with FHM, so I'm not putting any in this year. They had all last year to multiply, I could walk across the pond on their backs. Thanks to PB member's advise...I stocked the FHM last year and put off the stocking of the game fish until this year. The pond is loaded with forage...FHM, tadpoles (wintered well, could even see them through the ice), and water bugs. It's a blasted buffet for the soon to come stockings.
