Genetic Stock Structure of Herring in Prince William Sound, 2012-2015, EVOS Herring Program

These data are part of the Herring Program of the Exxon Valdez Oil Spill Trustee Council, project numbers 12120111-P, 14120111-P, and 16120111-P, which is a multi-faceted study to determine why herring populations in Prince William Sound (PWS) remain depressed since the early 1990s.

The purpose of this study was to examine the genetic stock structure of herring within PWS and the connections to herring stocks outside of PWS. Herring were collected from 2012 to 2015 in eastern and western PWS, and several locations adjacent to PWS, including Southeast Alaska, Yakutat and Kayak Island, Cook Inlet, Shelikof Strait, and Kodiak Island for genetic analysis. Bering Sea herring collected from 2005 to 2008 were included as outliers.

This dataset is a single comma-separated values (csv) file containing genetic information obtained from thirteen microsatellite loci and mtDNA cytochrome b (cytb) sequences. Genetic analyses was conducted at the NOAA- Alaska Fisheries Science Center, Auke Bay Laboratories in Juneau, Alaska. Analyses of the microsatellite loci show that allele frequencies of herring collections in eastern PWS are homogenous among bays, between year classes, and over years. Collections from Montague Island and Evans Island (western PWS) indicated a weak signal of differentiation from eastern PWS collections. PWS herring are genetically similar to herring east of PWS (Kayak Island and Yakutat), but are significantly different than herring west of PWS (Kodiak, Cook Inlet, and Shelikof Strait). Bering and Gulf of Alaska herring are highly divergent genetically.

本数据集为埃克森瓦尔迪兹溢油赔偿委员会（Exxon Valdez Oil Spill Trustee Council）鲱鱼项目的组成部分，对应项目编号为12120111-P、14120111-P及16120111-P。该多维度研究旨在探明1990年代初以来，威廉王子湾（Prince William Sound，简称PWS）内鲱鱼种群数量持续低迷的成因。

本研究的核心目标为解析威廉王子湾内部鲱鱼的遗传种群结构，以及其与湾外鲱鱼种群的遗传关联。研究团队于2012至2015年间，在威廉王子湾东西部及周边多个区域采集鲱鱼样本用于遗传分析，采样区域涵盖阿拉斯加东南部、亚库塔特（Yakutat）、凯阿克岛（Kayak Island）、库克湾（Cook Inlet）、谢利科夫海峡（Shelikof Strait）与科迪亚克岛（Kodiak Island）。此外，本数据集纳入了2005至2008年间采集的白令海鲱鱼样本作为外类群。

本数据集为单个逗号分隔值（CSV）文件，包含从13个微卫星位点（microsatellite loci）与线粒体DNA细胞色素b（mtDNA cytochrome b，cytb）序列中获取的遗传信息。遗传分析工作由位于阿拉斯加朱诺市的美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）阿拉斯加渔业科学中心奥克湾实验室（Auke Bay Laboratories）完成。微卫星位点分析结果显示，威廉王子湾东部采集的鲱鱼样本的等位基因频率在各海湾间、不同龄组间以及不同采样年份间均保持同质。来自蒙塔古岛与埃文斯岛（威廉王子湾西部）的样本则表现出与东部样本微弱的遗传分化信号。威廉王子湾鲱鱼与湾东侧的凯阿克岛、亚库塔特海域鲱鱼遗传特征相似，但与湾西侧的科迪亚克岛、库克湾及谢利科夫海峡海域鲱鱼存在显著遗传差异。白令海与阿拉斯加湾鲱鱼则呈现高度的遗传分化。
