Could be good, could be bad. Look at what the Tiger Musky eat. Usually rough fish like carp, squawfish, etc. It would be interesting to see what the Pike are feeding on in the Pond Oreille.
HUGE difference between the two. Tiger muskie are genetically sterile. Pike are not. Tiger muskie are planted by the state in an attempt to control other species(tench, carp, etc.) and eliminate a stunted population(perch,etc.). Pike will eat anything they can get ahold of. They are ambush predators. In the PO they eat just about everything. The largemouth fishery's decline has been blamed on the pike. I personally love fishing for pike, but if they reach the lower columbia they will put an end to salmon and steelhead fishing the way it is now.
Pike and Musky are both ambush predators and will both eat anything they can get ahold of. They are planted to remove problem fish because theres so many of the problem fish it presents a greater opportunity for the Musky to eat them. The Musky in Curlew eat both Largemouth and Rainbow Trout which are NOT target species.
Tiger Musky are sterile and that is why they are used to control problem fish, their populations can be managed. Pike obviously are not. The Columbia has very few areas in which Pike could successfully breed. It would be interesting to see if the Pike mainly feed on trash fish that are in the river in greater abundance most of the time, or the salmon.
