I guess you could say Pike are Coyotes of the water having but two predators; man and Musky. Sure wouldn't be much left having both Musky and Northern Pike in the same lake.
Musky population, of course, can be controled through hybridation which uses the Pike in the raising thereof.
Northern have no problem with spawning in lakes, criks, rivers, etc, as other species do.
Always likened catching a Pike in a lake to that of fighting a log until that log surfaces, then yinz better have the drag set and set right.
Catch em on a live bait under float, tossing jigs, spinners, spoons, plugs and I think on a bare hook. Darn things will eat anything except weeds..... sorry.
Find shallow water holding dead weed over a hump along deep water and drop dead cut on the bottom through the ice; sit back, chew on some deer jerky while, enjoying a hot cup of Captain Morgan Coffee.
But don't take my word for any of this because, as easy as it sounds, I can't catch this stupid fish... either!
I do however, know about the Morgan Coffee and the deer jerky**.
** When provided by others..... stupid deer!
