Book excerpt: This report serves as a first-year summary of progress of a contract study intended to document the timing and origins of chinook salmon, Oncorhynchus tshawytscha, stocks in the Copper River and adjacent ocean fisheries using DNA markers. The project is intended to investigate the genetic structure of chinook salmon from the Copper River drainage using both microsatellite and single nucleotide polymorphisms (SNPs). Identification of genetic stocks of chinook salmon within the Copper River drainage and knowledge of their run timing and migration patterns will provide valuable information to optimize management and provide for sustainable fisheries. The first objective of this contract study is to develop a DNA database to delineate major geographic and temporal stocks of chinook salmon within the Copper River. This objective requires collection of tissue samples as well as the laboratory DNA analyses of those tissues. A second objective is to investigate run timing and entry patterns within the Copper River through the analysis of radio-tagged and fishwheel samples from Baird Canyon. A third objective is to characterize the timing of Copper River stocks in the ocean fisheries and estimate the contribution to this fishery by stocks of non-Copper River origin. Finally, these data will be standardized and contributed to a coastwide DNA database so that Copper River chinook salmon can be tracked throughout their marine migration. This report reviews the first year of the study which concentrated on objective 1.

This book was released on 2017 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chinook salmon are harvested in subsistence, commercial, sport, and personal use fisheries throughout the Copper River drainage and in nearshore marine waters. This project was designed to estimate the stock-specific harvest of Chinook salmon in the Copper River District commercial drift gillnet fishery using genetics samples from 2013 through 2017. The Chinook Salmon Research Initiative identified the Copper River as 1 of 12 indicator stocks representing the diverse life history and migratory characteristics of Alaska Chinook salmon. Adult abundance information was identified as a fundamental knowledge gap, including the absence of programs to estimate stock-specific harvest in mixed stock commercial fisheries. This project applied the available baseline of genetic information representing Chinook salmon populations from within the Copper River drainage, around the Gulf of Alaska, and from southern populations to estimate the relative stock compositions of Chinook salmon harvests in the Copper River District commercial fishery. The results show that most of the fish in the Copper River commercial fishery originated from Copper River populations, which is consistent with findings from previous studies. A consistent temporal pattern in the composition of the commercial fishery harvests was observed across the 5-year study. As the season progressed, the proportion of Upper Copper River Chinook salmon decreased, and the proportion of Lower Copper River Chinook salmon increased. The unusually high proportions of nonlocal Chinook salmon in the commercial harvest occurring during 2 of the study years (2014 and 2015) align with other reports of large numbers of out-of-area Chinook salmon in commercial fisheries throughout the southern and southeastern seaboards of Alaska. The results support the historical commercial management approach of providing inriver passage for all temporal components of the run. Genetic data allow for estimating the stock-specific harvests of wild stocks or stocks (with and without coded wire tags) from other areas.

Book excerpt: This report summarizes progress in the development and implementation of genetic stock identification (GSI) in the Snake River basin for natural-origin steelhead and spring/summer Chinook Salmon for the 01/01/2020 to 12/31/2020 reporting period. Four objectives for the GSI project are addressed in this report: 1) the maintenance and evaluation of single nucleotide polymorphism (SNP) panels for high-throughput genotyping of steelhead and Chinook Salmon in the Snake and Columbia river basins; 2) the updating, maintenance, and testing of SNP baselines to describe genetic variation and for use as a reference in conducting GSI for both species; 3) the implementation of GSI to estimate genetic stock composition and life history diversity of steelhead and spring/summer Chinook Salmon passing Lower Granite Dam (LGR); and 4) the summarization of life history and genetic diversity information for steelhead and spring/summer Chinook Salmon detected at PIT tag detection systems. For both species, panels of up to 368 SNPs have been in use for GSI and parentage-based tagging (PBT) at both Idaho Department of Fish and Game’s Eagle Fish Genetics Lab, and its collaborating laboratory, the Columbia River Inter-Tribal Fish Commission’s Hagerman Genetics Lab. We present an updated Steelhead SNP baseline version 4, which consists of 43 collections and 2,719 individuals. Chinook Salmon SNP baseline v3.1 consists of 30 collections and 4,356 individuals. SNP baselines are used to describe genetic diversity and structure of natural-origin populations throughout the Snake River. Based on population structure we have defined 10 genetic stocks for steelhead and 7 genetic stocks for Chinook Salmon for GSI analysis at LGR. We summarize GSI results for returning adults and emigrating juveniles during 2019-2020 at LGR using v3.1 baselines as reference for both steelhead and Chinook Salmon. Finally, we describe the life history variation and genetic diversity of steelhead and Chinook Salmon detected at IPTDS. The information presented in this report provides critical data for viable salmonid population (VSP) monitoring of the Snake River steelhead DPS and the Snake River spring/summer Chinook Salmon ESU.

This book was released on 2019 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes an updated genetic baseline for Upper Cook Inlet Chinook salmon that allows for the identification of more stocks in mixed stock fisheries than previously possible. Chinook salmon are harvested in commercial, sport, subsistence, and personal use fisheries in Upper Cook Inlet, Alaska. Harvests often occur in areas where stocks intermingle, highlighting the need for understanding stock of origin in fishery catches to improve fishery management. Mixed stock analysis (MSA) has been used to estimate the stock composition of harvests in Cook Inlet since 2013. However, MSA applications have been limited by inadequate genetic structure, making northern Cook Inlet stocks of management and fishery importance difficult to distinguish: west Cook Inlet, Yentna River, and western Susitna stocks were indistinguishable; and eastern Susitna River and Matanuska River stocks were indistinguishable. Here we use cutting-edge genotyping by sequencing techniques to produce a baseline containing 67 Chinook salmon populations and 413 genetic markers and examine the baseline for population structure and test for potential reporting groups (stocks) using new baseline evaluation methods. Tests of potential reporting groups revealed 10 groups with adequate genetic divergence to meet the criteria for reporting groups. The 10 groups identified were (1) West, (2) Susitna, (3) Deshka, (4) Yentna, (5) Knik-Turnagain, (6) Kenai Mainstem, (7) Kenai Tributary, (8) Kasilof Mainstem, (9) Kasilof Tributary, and (10) South Kenai Pen. The data presented in this report will allow for more accurate, precise and finer-scale reporting group estimates for MSA studies in Cook Inlet and improved fisheries management.

Book excerpt: Tissue samples suitable for genetic analyses are being collected from fish species in the Susitna River basin, Alaska, for conducting genetic analysis of chinook salmon, and establishing tissue repositories for all four other salmon species and 20 non-salmon fish species. Chinook salmon tissue will be used to characterize genetic population structure, examine genetic variation for use in mixed-stock analysis, and, if sufficient variation is found, estimate the contribution of chinook salmon originating upstream of Devils Canyon to select habitats in the lower River. Salmon and non-salmon tissue repositories will be used for future studies to characterize the genetic legacy and variation of species and populations of interest. This document details Alaska Energy Authority's status in implementing the study as set forth in the FERC-approved Revised study plan and as modified by FERC's Study plan determination issued February 1, 2013.

This book was released on 2019 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chinook salmon Oncorhynchus tshawytscha stocks support important fisheries in Cook Inlet, Alaska. Many Chinook salmon stocks in Alaska have been in decline since 2007. Stock-specific harvest of Chinook salmon in the Cook Inlet marine sport fishery was identified as one of many information gaps hindering an understanding of the reasons for these declines. Here we report genetic baseline evaluation tests for mixed stock analysis and select mixed stock analysis results using genetic and coded wire tag data (gcMSA) from Chinook salmon harvested in the Cook Inlet marine sport fishery from 2014 to 2017. Results of the baseline tests indicated adequate genetic variation to distinguish among 4 reporting groups of interest to management (Outside CI, Northern CI, Kenai, and S. Kenai Pen.). The gcMSA results were obtained from 4,780 Chinook salmon sampled from the Cook Inlet marine sport fishery. Stock composition and stock-specific harvests were estimated for the Upper Cook Inlet early fishery and Lower Cook Inlet summer and winter fisheries for all 4 years and Upper Cook Inlet late fishery for 2016 and 2017 only. The Outside CI reporting group dominated all fisheries. The contribution of Cook Inlet Chinook salmon stocks was greatest in Upper Cook Inlet and ranged from 10.1% to 24.7% in the early fishery and from 3.5% to 18.0% in the late fishery. In Lower Cook Inlet, Cook Inlet stocks contributed 1.0 to 3.9% in the summer fishery and less than 1.0% of the harvest in the winter fishery in all 4 years.

Book excerpt: Recent low runs of Chinook salmon Oncorhynchus tshawytscha in Alaska have resulted in an increased interest in developing a more comprehensive genetic baseline. A genetic baseline will allow for examination of potential impacts of fisheries on Chinook salmon stocks using mixed stock analysis. Potential hatchery contributions to fisheries will be determined using parental based tagging of Pillar Creek Hatchery Chinook salmon. There are several stocks in the Westward Region that do not have good representation in the genetic baseline, specifically on the north Alaska Peninsula and adjacent areas and near and on Kodiak Island. This document describes a plan to sample the Chinook salmon stocks in these areas to improve the genetic baseline.

Book excerpt: Recent low runs of Chinook salmon Oncorhynchus tshawytscha in Alaska have resulted in an increased interest in developing a more comprehensive genetic baseline throughout the state. An updated genetic baseline will allow for additional spatial resolution when examination of potential impacts of fisheries on Chinook salmon stocks using mixed stock analysis. These sampling efforts resulted in surveys of 33 areas, 27 of which resulted in new Chinook salmon collections, with 15 of those with sufficient samples (>70 individuals) to add representation to the genetic baseline. This work increased the department's knowledge regarding the abundance and distribution of Chinook salmon on the Alaska Peninsula and Kodiak Island.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the application of genetic techniques to the management and conservation of anadromous salmonids (steelhead Oncorhynchus mykiss and spring-summer Chinook Salmon O. tshawytscha) in the Snake River basin. In 2010, Idaho Department of Fish and Game, in collaboration with the Columbia River Inter-Tribal Fish Commission, initiated two BPA-funded projects (2010-026-00 and 2010-031-00) to test and implement genetic monitoring programs for Snake River basin steelhead and spring-summer Chinook Salmon utilizing two genetic technologies that identify origins of hatchery and wild fish. The first technology, called parentage‐based tagging (PBT), involves annually sampling and genotyping all hatchery broodstock which are added to a genetic baseline of candidate parents. The genotyping of broodstock permanently genetically “tags” all of their offspring. A non‐lethal tissue sample from any offspring of these broodstock can be genotyped and analyses can be completed to assign parentage, thereby identifying hatchery of origin and age. The second technology is called genetic stock identification (GSI) and involves creating a reference genetic baseline from all contributing wild stocks. Wild fish of unknown origin can then be non-lethally sampled, genotyped, and assigned to a stock of origin via assignment testing. Over the last decade, these projects have demonstrated the accuracy, efficiency, and utility of these technologies for monitoring both wild and hatchery stocks throughout the Snake River and Columbia River basins. For hatchery stocks, PBT addresses objectives established by the Bonneville Power Administration (BPA) Fish and Wildlife Program which involves marking hatchery stocks, conducting hatchery evaluations and reform, and enforcing salmonid fishery management measures. For wild stocks, GSI provides unprecedented tools for monitoring wild stock abundance, productivity, and genetic diversity, which are required for NOAA ESA status assessments. These two projects were combined by BPA in 2021 (2010-031-00), with ongoing goals of keeping PBT and GSI baselines up-to-date in the Snake River basin, to maintain and enhance SNP genetic marker panels, and to continue projects that use these PBT and GSI baselines to address conservation and management issues of importance to the Northwest Power and Conservation Council and state, tribal and federal fisheries managers. Combined there are eight objectives addressed in this report: 1) the maintenance and evaluation of single nucleotide polymorphism (SNP) panels for high-throughput genotyping of steelhead and Chinook Salmon in the Snake and Columbia river basins; 2) the updating, maintenance, and testing of SNP baselines to describe genetic variation and for use as a reference in conducting GSI for both species; 3) annual sampling of hatchery broodstock and creation of genetic parental databases; 4) utilization of PBT and GSI baselines to estimate genetic stock composition and life history diversity of steelhead and spring-summer Chinook Salmon passing Lower Granite Dam (LGR); 5) application of PBT baselines to estimate the stock composition of steelhead in the Columbia and Snake River tribal and sport fisheries; 6) the monitoring of integrated hatchery programs for Chinook Salmon; 7) the summarization of life history and genetic diversity information for steelhead and spring-summer Chinook Salmon detected at PIT tag detection systems; and 8) the development and application of grandparentage technology for use in the Snake River basin.

This book was released on 2012 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncertainty about the magnitude, frequency, location, and timing of the nonlocal harvest of sockeye and chum salmon was the impetus for the Western Alaska Salmon Stock Identification Program. The program was designed to use genetic data in mixed stock analysis to reduce this uncertainty. A baseline of allele frequencies in spawning populations is required for use in mixed-stock analysis to estimate the stock of origin of harvested fish. This report describes the methodology used to understand the population genetic structure among chum salmon populations and to build and test a baseline for use in mixed stock analysis of chum salmon. Of the 35,921 fish from 434 collections selected to be genotyped, the final baseline was composed of 32,817 fish from 402 collections representing 310 populations. Average population sample size was 106 fish. Reporting groups were determined through a combination of stakeholder needs and identifiability using genetic information, as measured using proof tests. The final reporting groups included Asia, Kotzebue Sound, Coastal Western Alaska, Upper Yukon River, Northern District (Alaska Peninsula), Northwest District (Alaska Peninsula), South Peninsula (Alaska Peninsula), Chignik/Kodiak, and East of Kodiak.
