Experimental data from long-term elevated pCO2 exposure in Pacific herring. Datasets include measurements of enviromental treatment conditions, growth and developmental traits, and mortality data from a disease challenge.

This study evaluated the effects of ocean acidification on the health, survival, fitness, and disease susceptibility of early life stage Pacific herring. Wild larvae were reared from hatching under three pCO2 treatments [low (~650 μatm), intermediate (~1,500 μatm), and high (~3,000 μatm)] to determine the effects of elevated pCO2 on larval growth, yolk consumption, and foraging capabilities and to evaluate how chronic exposure to elevated pCO2 affects long-term growth and maximum swimming speed. After prolonged exposure (98 d), we tested how elevated pCO2 experienced during development altered the susceptibility of juvenile Pacific herring to VHS following water-borne exposure to VHSV. This directory includes datasets for: 1) daily pH and temperature measurements from replicate rearing tanks; 2) carbon chemistry measurements from discrete seawater samples; 3) morphometric and feeding data for larval herring (1 - 16 days post hatch); 4) standard length measurements from larval and juvenile samples (1 - 98 days post hatch); 5) All dry mass measurements from larval and juvenile samples (1 - 98 days post hatch); 6) survival statistics for whole experiment ( 1- 98 days post hatch); 7) maximum swim speed measurements on juvenile herring; 8) disease challenge mortality and viral titer data; 8) a README file containing information on the dataset.本研究评估了海洋酸化对太平洋鲱鱼（Pacific herring）早期生命阶段的健康状况、存活率、生存适合度以及疾病易感性的影响。研究人员将野生鲱鱼幼体从孵化阶段起，置于三种二氧化碳分压（pCO2，partial pressure of carbon dioxide）处理组——低浓度组(~650 μatm)、中浓度组(~1500 μatm)与高浓度组(~3000 μatm)——中进行饲养，以明确升高的pCO2对幼体生长、卵黄消耗与觅食能力的影响，并评估长期暴露于升高pCO2环境如何影响其长期生长与最大游泳速度。在经过98天的长期暴露后，本研究测试了发育阶段所处的升高pCO2环境，如何改变幼年太平洋鲱鱼经水体暴露于病毒性出血性败血症病毒（VHSV，Viral Hemorrhagic Septicemia Virus）后对病毒性出血性败血症（VHS，Viral Hemorrhagic Septicemia）的易感性。本数据集目录包含以下内容：1) 重复饲养养殖桶的每日pH值与温度监测数据；2) 离散海水样本的碳化学参数测量数据；3) 孵化后1~16日龄鲱鱼幼体的形态学与摄食相关数据；4) 孵化后1~98日龄鲱鱼幼体与幼鱼的标准体长测量数据；5) 孵化后1~98日龄鲱鱼幼体与幼鱼的全部干重测量数据；6) 整个实验周期（孵化后1~98日龄）的存活统计数据；7) 幼年鲱鱼的最大游泳速度测量数据；8) 疾病攻毒后的死亡率与病毒滴度数据；8) 包含数据集说明信息的README文件。
