NMFS plans-- based upon applications received from NMFS' Southeast Fisheries Science Center and Texas Parks and Wildlife Department--to issue proposed regulations to govern the unintentional taking of marine mammals incidental to survey activities conducted in support of fisheries management. The proposed regulations will set forth the permissible methods of taking; means of effecting the least practicable adverse impact on the affected species or stocks and their habitats and, if applicable, on their availability for taking for subsistence uses (i.e., mitigation); and requirements pertaining to the monitoring and reporting of such taking. Letters of Authorization issued under the regulations would authorize the take of marine mammals incidental to the specified activities for a 5-year period.
