You can stock all the FHM you want but only so many fry will survive due to the right amount of plankton to grow them.
The first part of the hatch will be spawning before summer's end-if they have ample food.
Adult FHM are very seldom seen except for black head males guarding nests, and I am sure a few get consumed by YP but YP also take advantage of other items developing in the pond.
