The requirement for cleaning vessels and boats shall be enforced regardless of the size or type of the vessel or boat and shall be uniform throughout the State.(b) Each vessel shall keep a written log which shall be available to the inspection service. Records of net boats shall show the time of each set.(c) No decomposed chum may be used for bait or in taking mackerel. All bait or chum used must be fresh (not over 24 hours old) unless it be salted or frozen.(d) High seas fishing boats, whether net or bait, shall keep a record of their catch and their methods of handling fish, including hold and water temperature.(e) The Department of Public Health or its authorized agent may require interested parties, including members of the laboratory staff, to appear when undue quantities of fish have been condemned. Inquiry shall be made of the fishermen to determine the methods used in fishing and handling.
