1,keep mobile, move every half hour or so, if you catch a jack or two consider waiting for a big girl in that swim.
2, try baits on the deck and mid water, trotted deads or paternoster float deadbait rigs work well for me.
3, try all areas in each swim, pike layed up in wait will often not move more than 6 foot or so for a meal
4, keep trying!
