At the top of any list of northern
pike fishing tips, you should learn this one first - how to handle a pike after you have caught one. There are few freshwater fish that compare to the fight you will have with a northern pike once you have one on the hook. However, unlike you would when largemouth bass fishing, you don't want to bring a northern pike into the boat to unhook it.
The reason is that northern pike have razor sharp teeth and gills and will start thrashing around in the bottom of the boat at the most inopportune time, i.e. when you are trying to get your lure unhooked and out of its mouth. Imagine a fish that is all muscle with three treble hooks hanging out of its razor-sharp mouth thrashing wildly in the bottom of your boat, or worse, canoe. You could get in trouble fast.
In fact, old-timers might tell you to bash the pike in the head if you get one in the boat with you. (For example, maybe you weren't even
pike fishing but you or a companion in the boat brought one in unknowingly.)
However, if you do in fact want to go pike fishing and want to know how to properly unhook one so that you don't hurt yourself or the fish, the best suggestion is to find a guide or friend who is knowledgeable about pike fishing to help you learn how to unhook a northern pike in a way that doesn't harm the fish or, more importantly, yourself or those with you in the boat.
A good fishing guide can show you how to unhook the smaller pike from the side of the boat, keeping the fish in the water, while showing you techniques to bring a larger one into a place on the shore to safely unhook, take pictures, and release the fish.
Pike are tremendous fun to catch but that fun can turn ugly quick if you don't know how to handle one. Seek the advice of someone that can show you a safe way first before you try to unhook one yourself.
