Or, you can check out a more recent PB article that recommends pike for ponds with overcrowded bass populations, and it was written by the same author who wrote the ealier article disrecommending them:
http://www.bassresource.com/fish_biology/walleye-bass-perch.htmlYears ago I stocked 20 - yes, 20 - 12" northern pike into a pond that might be three acres total in size, and which at the time was morbidly overpopulated with green sunfish; I stocked 40 yearling LMB that same year, and a year later 75 6" walleye (the pond has lots of water over 20' feet deep, some holes over 30'). The pond is an old phosphate pit and thus very fertile, so it probably carries more fish per acre than the average pond; but the pike didn't decimate the population of the pond, anything but; within three or four years the pond had some of the best LMB fishing, and bluegill fishing, of any pond I've ever fished, very large specimens of both species, and plenty of them. My best friend caught his personal best LMB, almost eight pounds; numerous LMB in the four- to six-pound range were caught; and my grandfather lost one that probably would've gone in the mid-teens - and these were northern-strain largemouth, not FLA's. A 36" NP was caught somewhere around that time, and a couple years after that a nine-pound walleye was caught from the pond.
Also, the article linked to above is anything but an exhaustive study - no data is given, and it would seem to be clear that none was known, about what the pond contained, if anything, other than the pike and green sunfish, at earlier dates, i.e. it's very possible that there was never a large population of green sunfish, or anything else; there's no evidence at all that bluegill or largemouth either one were ever even present in the pond. So to conclude that pike will invariably clean out a pond with bass and bluegill, based on a pond that may never have had either species, is not very sound.
Lastly, the article clearly states that in every body of water studied other than ones in which pike were present at extremely high densities (overpopulated), average bass size increased significantly with the presence of pike, and in most of the BOW studied, average bluegill size was high as well.
