"A genetic monitoring program for beluga harvested in Nunavik and Nunavut-Belcher Islands management units is ongoing at Fisheries and Oceans Canada (DFO). With this document, we aim to increase transparency in methods used and enable reproducible results in other laboratories analyzing similar tissues. This document presents 1) the extent of the tissue collection from Nunavik, 2) an improved haplotyping method, 3) an improved sex determination method, and 4) results for individual genetic assignment to the populations/stocks in the Hudson Bay-Strait Complex. Our results for the individual genetic assignment show that the updated genetic definition of the beluga summering in the distribution of the Eastern Hudson Bay designatable unit, recently identified as the Belcher Islands and Eastern Hudson Bay (BEL-EHB) stock, has led to increased uncertainty associated with this method. The high uncertainty makes this approach unsuitable for providing seasonal estimates of the number of BEL-EHB animals harvested in Nunavik and Nunavut-Belcher Islands. The alternative approach for annual updates of populations or stocks proportions harvested in Nunavik and Nunavut-Belcher Islands management areas is discussed"--Abstract, page vi.
