Herring Infection Prevalence Data, 2007-2023, EVOS Herring Program

The project was designed to assess the prevalence and intensity of several pathogens (viral hemorrhagic septicemia virus (VHSV),viral erythrocytic necrosis (VEN), and Ichthyophonus) in herring populations from 2012 to 2023 in Prince William Sound (PWS). Other reference herring populations from Sitka, Alaska were periodically sampled outside PWS. The dataset is 20 tabular data files in comma-separated values (csv) format containing standard headers including fish length, weight, positive / negative data for each pathogen, and pathogen loads, when applicable. Files are organized by year (2012 to 2023) and sample location (Stika and PWS). Additionally, a single csv file contains a summary of infection prevalence ratios (VHSV, VEN, and Icthyophonus) for PWS from 2007 to 2016. Data from 2007 to 2011 were collected under the EVOS PWS Herring Disease Program, project numbers 070819 and 10100132-I. These data are part of the Herring Program of the Exxon Valdez Oil Spill Trustee Council, project numbers 070819, 10100132-I, 12120111-K-21120111-K, which is a multi-faceted study to determine why herring populations in Prince William Sound remain depressed since the early 1990s.本项目旨在评估2012至2023年间威廉王子湾（Prince William Sound, PWS）内鲱鱼种群中多种病原体的感染率与感染强度，涉及的病原体包括病毒性出血性败血症病毒（viral hemorrhagic septicemia virus, VHSV）、病毒性红细胞坏死症（viral erythrocytic necrosis, VEN）以及Ichthyophonus。此外，研究团队还定期于威廉王子湾外部采集了来自阿拉斯加锡特卡（Sitka）的对照鲱鱼种群样本。本数据集包含20个逗号分隔值（Comma-Separated Values, CSV）格式的表格数据文件，所有文件均带有标准表头，内容涵盖鱼体体长、体重、各病原体的检测阳性/阴性结果，以及适用场景下的病原体载量。这些文件按照采样年份（2012至2023年）与采样地点（锡特卡与PWS）进行分类整理。此外，另有一个CSV格式文件汇总了2007至2016年间威廉王子湾内三种病原体（VHSV、VEN与Icthyophonus）的感染率统计数据。2007至2011年的相关数据由埃克森瓦尔迪兹石油泄漏赔偿委员会（Exxon Valdez Oil Spill Trustee Council, EVOS）下属的威廉王子湾鲱鱼病害项目采集，项目编号分别为070819与10100132-I。上述数据隶属于埃克森瓦尔迪兹石油泄漏赔偿委员会的鲱鱼研究项目，对应项目编号包括070819、10100132-I、12120111-K与21120111-K；该项目为多维度研究，旨在探明自20世纪90年代初以来威廉王子湾鲱鱼种群数量持续低迷的原因。
