well we keep a gallon pickle jar on the boat just in case ,you put a hole in the top of the lid and you tie a 1/4 in rope thru the whole with a knot on the end you put about a dozen crappie minnows inside the jar ,fill with water and lower over the side until you reach the depth of the inactive fish and sometimes this will trigger the crappie to start bitting if they are in a nonactive pattern.
