The best thing that I find if you should decide to keep Pike is to keep them dry,and away from water.Any moisture will cause the fish to expell the slime even more,diddo on walleye also.I spotted a guy last summer well at my cabin at shaws with 3 walleyes that were dripping slime,he seemed to be convinced the walleye were naturally slimey.I asked him if he had them in water,yep!!!I told him that just made them slimey for him.I dont think he ever did that again....
