If you give the forage fish a year to get their numbers up, you will have countless numbers of frogs and amphibians as there are no predators.
I plan on giving the forage species a year's head start. Probably not the threadfin shad and the gizzard shad won't be added until AFTER there are large bass in the pond.
I would consider putting mud puppies in with the initial stocking of forage if I could find HUGE adults, but I would never intentionally add frogs without predators in the water. I would not want 50,000 frogs in my pond next season LOL.
