Sockeye Sample Inventory

The project sponsor (IDFG) purchased the Progeny database software, which is a multi-user relational genetic database for cataloging genetic samples and storing genotypes. They subsequently catalogued over 6,000 samples as part of Redfish Lake Sockeye captive broodstock program, over 3,000 samples as part of the Chinook salmon captive rearing project, and over 12,000 samples as Genetic Stock Identification (GSI) and Parentage-Based Tagging (PBT) programs for Snake River steelhead and Chinook salmon.

They used the Progeny to manage genotypes for all of these samples (both microsatellite and Single Nucleotide Polymorphism data) and reported that all deliverable were completed as proposed.

The software allows for the cataloging of unlimited quantities of phenotypic and genotypic data into a single, secure, multi-user relational database.

All genetic samples as part of the ESA-listed Snake River sockeye salmon captive broodstock program are inventoried using the Progeny database. In addition, the genetic data that is stored and managed in the database is used to address research, monitoring and evaluation needs associated with: Identifying the source of out-migrants in Redfish Lake (whether these fish were produced by non-listed kokanee or ESA-listed residual sockeye), evaluating relatedness among returning anadromous adults to guide broodstock management, building spawning matrices to avoid inbreeding and maintain genetic diversity, tracking the effective population size of the captive broodstock population and returning anadromous adults, Evaluating program release strategies using parentage analyses, determining the composition of O. nerka (sockeye and kokanee) in nursery lakes to evaluate population abundance and productivity, and determining the composition of O. nerka (sockeye and kokanee) in annual creel surveys for ESA permitting issues.

No deviations were reported. Please see the final report attached to this project record for more details.

PCSRF funding for this project would benefit all listed and non-listed anadromous salmonid stocks in Idaho (Snake River sockeye salmon O. nerka, Snake River Spr/Su/Fall Chinook salmon O. tshawytcha, Snake River steelhead O. my kiss, etc). More specifically, the genetic software purchased for this project will be used to construct and follow pedigrees of Snake River sockeye broodstock, which will allow managers to preserve genetic resources and monitor hatchery effectiveness. This software will also be used to manage and track samples and genetic data as part of genetic stock identification and Parentage Based Tagging monitoring programs for Snake River steelhead and Chinook salmon. These programs will benefit these ESA listed species by reducing critical uncertainties related to estimating stock composition and stock-specific abundance, escapement, catch, and age distribution.
