NMFS issues regulations to revise the at-sea scales program for catcher/processor vessels (C/Ps) and motherships that are required to weigh catch at sea. This action makes three major changes to current regulations. First, this action requires enhancements of daily scale testing for flow scales used to weigh catch at sea and requires electronic reporting of the daily flow scale test results. Second, this action requires that vessels required to use flow scales to weigh catch have electronics capable of logging and printing the frequency and magnitude of scale calibrations, as well as the time and date of each scale fault (or error) and scale startup. Third, this action requires that vessels use video to monitor the flow scale and the area around the flow scale. In addition, this action revises minor technical regulations related to equipment and operation regulations and removes certain regulations that are no longer applicable; and improves the accuracy of catch estimation by the C/Ps and motherships using at-sea scales and reduces the possibility of scale tampering. This action is intended to promote the goals and objectives of the Fishery Management Plan for Groundfish of the Bering Sea and Aleutian Islands Management Area, the Fishery Management Plan for Groundfish of the Gulf of Alaska, the Magnuson-Stevens Fishery Conservation and Management Act, and other applicable laws.
