Zonal Advisory Meeting of the National Marine Mammal Peer Review Committee (NMMPRC): Baffin Bay Narwhal - Population level sustainable harvest calculation; April 1, 2011

Chairperson: Don Bowen


The National Marine Mammal Peer Review Committee (NMMPRC) held a zonal science peer review on April 1, 2011, via WebEx and teleconference. The purpose of this meeting was to determine (1) the Potential Biological Removal (PBR) calculation and associated Total Allowable Landed Catch (TALC) recommendation for the aggregate Baffin Bay narwhal population, and (2) what caveats are required to clarify the risks to individual summering stocks within the Baffin Bay population of managing the TALC at the population level. A draft Science Advisory Report was distributed prior to the meeting. Meeting participants included Fisheries and Oceans Canada (DFO) Science (National Capital, Newfoundland and Labrador, Maritimes, Quebec and Central and Arctic regions), DFO Fisheries Management, the Nunavut Wildlife Management Board, the United States National Oceanic and Atmospheric Administration – National Marine Fisheries Service and an independent expert from Portugal. A working paper was drafted and distributed prior to the meeting. During the meeting, participants discussed advice on abundance and sustainable harvest levels at the population level for Baffin Bay narwhal and the assumptions inherent in the advice. This proceedings report summarizes the relevant discussions and presents the key conclusions reached at the meeting. The Science Advisory Report will be published once it becomes available on the DFO Canadian Science Advisory Secretariat Website at
