R.I. Gen. Laws § 20-5-13
On or before the tenth day of January in each year, every person holding a permit pursuant to this chapter shall notify the department of environmental management in writing, under oath, what traps were placed under the permit during the preceding calendar year. Failure to furnish this information makes the permit null and void after that date. Failure to place a complete fish trap on a permitted location for a part of one calendar year may, in the discretion of the director of environmental management, make the permit for the fish trap null and void and the location will then become available for any suitable applicant. A permit for a fish trap location becomes null and void upon the removal of the holder from the state.
