SNP genotype dataset from brown and anadromous trout

Populations of anadromous brown trout, also known as sea trout, have suffered recent marked declines in abundance due to multiple factors, including climate change and human activities. While much is known about their freshwater phase, less is known about the species’ marine feeding migrations. This situation is hindering the effective management and conservation of anadromous trout in the marine environment. Using a panel of 95 single nucleotide polymorphism markers we developed a genetic baseline, which demonstrated strong regional structuring of genetic diversity in trout populations around the English Channel and adjacent waters. Extensive baseline testing showed this structuring allowed the high-confidence assignment of known-origin individuals to the region of origin. This study presents new data on the movements of anadromous trout in the English Channel and southern North Sea. Assignment of anadromous trout sampled from 12 marine and estuarine localities highlighted contrasting ..., All individuals were genotyped at 95 biallelic single nucleotide polymorphism (SNP) loci (Osmond, King, Stockley, Launey, & Stevens, 2023) on the Fluidigm EP1 Genotyping System using 96.96 Dynamic Genotyping Arrays and scored using the Fluidigm SNP Genotyping analysis software., , # SNP genotype dataset from brown and anadromous trout [https://doi.org/10.5061/dryad.1ns1rn92w](https://doi.org/10.5061/dryad.1ns1rn92w) Data for trout (*Salmo trutta*) samples genotyped at 95 single nucleotide polymorphism (SNP) markers (Osmond et al. 2023). Data consists of 3067 baseline trout samples, 435 known-origin individuals, and 371 anadromous trout caught in marine and estuarine areas. ## Description of the data and file structure The data file is a Microsoft Excel file, in GenAlEx format (Peakall & Smouse 2006, 2012), containing six tabs: Baseline_sample_info, Baseline, Known_origin_sample_info, Known_origin_samples, Marine&Estuarine_sample_info, and Marine&Extuarine. SNP data is coded as 1 - A, 2 - C, 3 - G, and 4 - T. Missing data is coded as zero. ### Tab: Baseline\_sample\_info A table presenting details of the rivers and hatchery populations from which brown trout were sampled to construct the genetic baseline, including river code name, country, repo...溯河洄游褐鳟（又称海鳟）的种群数量近期因气候变化、人类活动等多重因素出现显著下降。尽管学界对其淡水生活阶段已有较为充分的研究，但对该物种的海洋摄食洄游行为所知甚少，这一现状制约了溯河鳟在海洋环境中的有效管理与保护。 研究团队利用95个单核苷酸多态性（single nucleotide polymorphism, SNP）标记构建了遗传基线，结果显示英吉利海峡及邻近海域的褐鳟种群遗传多样性存在显著的区域遗传结构。广泛的基线验证实验表明，该遗传结构可将已知起源的个体高精度、高置信度地分配至其起源区域。本研究提供了英吉利海峡与北海南部海域溯河鳟移动模式的全新数据。对采自12个海洋及河口区域的溯河鳟进行遗传分型的结果显示出显著差异…… 所有个体均在Fluidigm EP1基因分型系统上，采用96.96动态基因分型阵列完成95个双等位基因单核苷酸多态性（SNP）位点的基因分型，并通过Fluidigm SNP基因分型分析软件完成分型评分（Osmond、King、Stockley、Launey及Stevens, 2023）。 # 褐鳟与溯河鳟SNP基因型数据集 相关DOI：https://doi.org/10.5061/dryad.1ns1rn92w 本数据集包含经95个单核苷酸多态性（SNP）标记完成基因分型的褐鳟（*Salmo trutta*）样本数据（Osmond et al. 2023），涵盖3067份基线褐鳟样本、435份已知起源个体样本，以及371份采自海洋与河口区域的溯河鳟样本。 ## 数据与文件结构说明 本数据集文件为Microsoft Excel格式，采用GenAlEx格式（Peakall & Smouse 2006, 2012），包含6个工作表：Baseline_sample_info、Baseline、Known_origin_sample_info、Known_origin_samples、Marine&Estuarine_sample_info以及Marine&Extuarine。 SNP数据编码规则如下：1代表碱基A，2代表C，3代表G，4代表T；缺失数据编码为0。 ### 工作表：Baseline_sample_info 该表格详细列出了用于构建遗传基线的褐鳟样本来源河流及孵化场种群信息，包括河流代码名称、国家、repo……
