The problem with pike and musky is they eat what is easiest for them, no necessarily what you want them to... Pike and musky may feed heavily on the gshad, but they may also feed heavily on your YP, walleye and other fish you really don't want them eating... I am not saying there isn't a place for pike or musky in pond management, but it is a very tricky balancing act with lots of room for error to happen. If you're going to use an esox species, use the tiger musky to prevent natural reproduction which may happen with NP. In a pond smaller than 5 acres, I don't think pike or musky should even be considered... In ponds 5 acres and bigger, stocking 1 or 2 a year or every other years is a possibility...
