Description

Sockeye salmon genetic samples were collected at the Chignik River weir from 2014 to 2017. Annually, a total of six strata samples of approximately 190 fish were collected and used to quantify the contribution of the two temporally overlapping Black (early run) and Chignik (late run) lakes sockeye salmon stocks to the Chignik River escapement estimates. Stock composition results were used to make inseason management decisions in the commercial fishery and for run reconstructions to accurately build brood tables.

Project Benefit

The communities of the Chignik area depend on both early- and late-run sockeye salmon for subsistence needs. Results from this work will aid in the effective management and maintenance of Chignik sockeye salmon stocks, allowing stock-specific inseason management actions to ensure escapement needs for each stock are met and surplus fish are available for both early and late season subsistence fisheries.

Key issues addressed by genetic analysis research

Two genetically distinct populations of sockeye salmon have significant temporal overlap in their escapement timing to the Chignik River watershed. Both stocks are important subsistence resources for local harvesters, and inseason mixed-stock analysis provides managers with the best possible information to target run-specific escapement levels which provide run-specific opportunity for subsistence harvests. For three years, tissue samples were collected from 190 fish at each of six points within this overlap timing; these samples were analyzed within 24 hours and the results relayed to managers in order to adaptively manage harvests to ensure that escapement goals are met and subsistence resources are managed sustainably.
