Actually, Amur Pike were introduced in a small section of central PA years ago but the population is diminishing to the point where it's almost gone thankfully, we don't need an invasive with that much predatory potential.Well it's a northern pike obviously. There is only two esox species that has a name pike. It would be Northern and Black spotted (Amur) but northern pike are widespreading species that can be found in North America, Europe and Asia where Amur pike is strictly isolated to the Amur River systems in Siberia.
Divemaster99, Amur Pike that was introduced to PA is pretty much nonexistent right now and there are no reports of Amur Pike being caught for years. Amur pike was unable to outcompete our native esox species and they did hybridized with northern pike but eventually their genes were disappearing as well. Therefore that's why you can find Amur pike in their native range only as you won't find them in PA.Actually, Amur Pike were introduced in a small section of central PA years ago but the population is diminishing to the point where it's almost gone thankfully, we don't need an invasive with that much predatory potential.
