There's no statewide closed season for carp in Illinois. There are some site specific lakes that have a season. Hard water puts a bit of a damper on carp shooting too.
we don't have a season here ,they have a bowfishing tourney ,come weigh them and whoever wants them get them ,and the rest are buired with a backhoe.O yes the tourney is all night.[8D][8D][8D][8D]some weigh in at 40 and 50 lbs.I love to catch them on light tackle ,then I release them .
