Pike eat a lot of fish per year, especially when larger. I often see fish farms saying stock a pike or two per acre and they'll not only thin out your stunted "whatever" but will also grow large themselves. In rare situations, this may be the case but it's unlikely. Pike, can if the conditions are right spawn in a pond. They do it and you're in for a stunted mess of pike and little else. So if you want a pike like species, I'd choose tiger musky or even pure musky over them.

Also, you're going to lose many of the stocker trout you stock to pike predation. That could get very costly! The likelihood of trout successfully reproducing and then recruiting to harvest size in your pond is unlikely. SMB can be managed by hook and line angling. I doubt you'll need help from pike.
