The director may:
A certificate of the director that service has been made under clause (14) shall be sufficient proof thereof. The supreme judicial or the superior court shall, on petition of the director, have jurisdiction in equity to enforce any such order and to restrain any violation thereof. If the director deems that a passage for anadromous fish should be provided, or if he finds that there is no fishway in or around a dam or obstruction where a fishway is required by law to be maintained, he may enter with workmen and materials upon the premises of the person required to maintain a fishway there and may, at the expense of the commonwealth, if in his opinion the person required by law to construct or maintain such fishway is unable to afford such expense, otherwise at the expense of the owner of or the person using or maintaining, such dam, improve an existing fishway, or cause one to be constructed if none exists, and may, if necessary, take the land of any other person who is not obliged by law to maintain said fishway. If a fishway has been constructed in accordance with this section he shall not require the owner of or the person using or maintaining the dam or other obstruction to alter such fishway within five years after its completion. All damages caused by taking land under this paragraph shall be recovered from the commonwealth under chapter seventy-nine. The amount so recovered shall be a charge against the person required by law to construct and maintain such fishway and shall be recovered in contract in the name of the commonwealth, with costs and with interest at the rate of twelve per cent per annum.
No order issued under this clause shall be deemed to prohibit the possession or use of any rifle during the daylight hours on any target range used primarily for target shooting purposes or the use of a primitive firearm with a rifled bore if authorized by the director with the approval of the board acting under the provisions of section five.
Whoever violates any order issued under the provisions of this clause shall be punished by a fine of not less than one hundred dollars nor more than five hundred dollars or by imprisonment for not more than six months.
