R.I. Gen. Laws § 20-5-14
Upon ceasing to use any fish trap as authorized, that structure shall at once be removed by the owner at the owner's expense and to the satisfaction of the director of environmental management. Failure to remove it shall be considered sufficient grounds for prosecution of the owner for maintaining a public nuisance or for revocation of the fish trap permit. Unless otherwise specified by regulations adopted by the marine fisheries council, all fish traps authorized in this chapter shall be completely removed by or before the last day of December of each year and no fish trap shall be reset before the first day of the following March. All submerged or broken stakes must be promptly removed. Any fish trap damaged or allowed to get into a dilapidated condition will be regarded as abandoned unless promptly removed or rebuilt. Failure to do this will subject the owner to prosecution and forfeiture of the trap.
