Taku River Sockeye Salmon Genetic Stock Identification Analysis for Commercial Samples

This proposal involves genetic analysis of tissue samples anticipated from the in-river commercial sockeye fishery on the Taku River in 2019. This activity was first supported by the Northern Fund in 2008 and makes use of the baseline samples collected with Northern Fund assistance from 2007-12.

This will identify the composition of the commercial harvest by stock groupings. In addition, when coupled with escapement counts from headwater counting fences (weirs), it will permit estimation of drainage-wide abundance for comparison with the mark-recapture estimate or other assessment methodology.
