Evaluating impacts of a flexible quota system on walrus harvesting / M.O. Hammill, A. Mosnier, R. Young.: Fs70-5/2016-112E-PDF
"Various model scenarios were run to determine the sustainability of a system allowing flexible catch limits of walruses involving carry-overs or credits between years over a five-year period. Two modeling approaches were examined. In the first, population numbers are projected over a period of 100 years with harvest rates based on PBR updated from estimates of the population every ten years. Results of model runs indicate that modelling scenarios with harvest debits or credits from year to year were not significantly different from the base model with no credit or debit between years. These results indicate that a flexible harvest limit system can be sustainable, as long as the five year total remains less than or equal to the total quota for the five years (i.e. five times the PBR), as was the case in our model runs"--Abstract, p. iv.
