520 |a"Walrus in the Canadian Arctic have been divided into two genetic populations and seven stocks based on genetic, isotope, satellite tag, and elemental analysis. Two stocks, located in Foxe Basin, are managed as a single group. DFO Science has provided abundance estimates and sustainable harvest advice on four stocks and one partial stock: the Baffin Bay (BB), Western Jones Sound (WJS) and Penny Strait-Lancaster Sound (PS-LS) units belonging to the high Arctic population and for the Foxe Basin and the southeast Baffin Island portion of the Hudson Bay-Davis Strait (HBDS) stock, belonging to the central Arctic population. Owing to limited survey effort, walrus stocks are considered data poor with respect to the assessment of population status. DFO has used the Potential Biological Removal (PBR) method to develop advice about sustainable removals for marine mammals considered data poor. PBR refers to all human-caused mortality so estimating a Total Allowable Removal (TAR) provides the level of removals from all human-caused mortalities that should allow the population to maintain an optimal population size, or grow. The purpose of this document is to use recent aerial survey information to estimate TARs for these two walrus stocks"--p. 4.
