WE Walleye, NP Northern Pike, don't need to apologize, the only stupid ?s are the ones not asked. I am puter challenged and don't know how to direct you but there is a list of abbreviations here that someone will probably guide ya to.
I don't think you can unstunt the fish, by adding predators and decreasing the YP #s you may enable the remaining fish to grow better.
You are already wise in thinking that fisheries will tell ya and sell ya anything. Probably be wasted money if the pond is way overstocked, to expect to establish minnows is doubtful but I'm not sure. A 1-2" minnow is the perfect size for your existing YP. Eliminate a bunch of small YP Yellow Perch and it lessens the predation of any minnows added. Any fish will expend as few calories to eat as possible. So a 16" WE would rather eat a 3-4" YP than 3 or 4 1" FHM Fat head Minnows.


Do nature a favor, spay/neuter your pets and any weird friends or relatives.
