Reproductive data of hydrothermal vent alvinocaridid shrimps collected in the Atlantic and Indian Oceans

Shrimps were collected from three hydrothermal vent fields: TAG and Snake Pit (Mid-Atlantic Ridge) and Kairei (Central Indian Ridge), during several cruises: the HERMINE cruise in 2017 on board RV Pourquoi pas ? (https://doi.org/10.17600 /17000200), the BICOSE 2 cruise in 2018 on board RV Pourquoi Pas ? (https://doi.org/10.17600/18000004), the YK01-15 cruise in 2002, the YK09-13 cruise in 2009 and the YK16-E02 cruise in 2016, all three on board RV Yokosuka (Jamstec). Size and sex of 4736 adult individuals belonging to Rimicaris exoculata (3793), Rimicaris chacei (147) and Rimicaris kairei (796) were determined. Reproductive characteristics including fecundity, egg developmental stage and egg size were analysed in 263 brooding females from the dataset. In addition, eggs of 60 R. exoculata brooding females from TAG and Snake Pit collected in 2014 during the BICOSE cruise (https://doi.org/10.17600/14000100), with sizes measured by Ivan Hernandez-Avila (available here: https://doi.org/10.17882/84112), were re-measured by P. Methou who produced this dataset for comparison with brooding R. exoculata collected in 2017 and 2018. New egg measurements of these 60 females are included here. Samples were preserved in ethanol or in formalin (followed by water washing and storage in ethanol) on board, then brought back to the laboratory for processing. They were analysed at the LEP (Laboratoire Environnement Profond, Ifremer, Centre de Bretagne, France; https://wwz.ifremer.fr/deep_eng/), as well as at the X-STAR Institute (Jamstec, Japan; https://www.jamstec.go.jp/xstar/e/). Results of the analysis of the dataset are available on BioRxiv: https://doi.org/10.1101/2021.09.10.456763, and are under review for Ecology & Evolution.
The dataset consists of two files: one containing the data itself, and one describing all used terms (measurements or metadata).

虾类样本采集自三个热液喷口场（hydrothermal vent fields）：TAG和Snake Pit（大西洋中脊，Mid-Atlantic Ridge）、Kairei（印度洋中脊，Central Indian Ridge），采集工作通过多个航次完成：2017年HERMINE航次（搭乘科考船RV Pourquoi pas?，https://doi.org/10.17600/17000200）、2018年BICOSE 2航次（搭乘科考船RV Pourquoi Pas?，https://doi.org/10.17600/18000004）、2002年YK01-15航次、2009年YK09-13航次及2016年YK16-E02航次（后三个航次均搭乘日本海洋研究开发机构（Jamstec）科考船RV Yokosuka）。共测定了4736只成体个体的体长与性别，这些个体分属Rimicaris exoculata（3793只）、Rimicaris chacei（147只）及Rimicaris kairei（796只）。本数据集对263只抱卵雌虾的繁殖特征（包括繁殖力、卵发育阶段及卵大小）进行了分析。此外，2014年BICOSE航次期间在TAG和Snake Pit采集的60只R. exoculata抱卵雌虾的卵，此前由Ivan Hernandez-Avila完成测量（数据可通过https://doi.org/10.17882/84112获取），本次数据集制作者P. Methou对其进行了重新测量，以与2017年和2018年采集的抱卵R. exoculata进行比较。这60只雌虾的新卵测量数据已纳入本数据集。样本在船上采用乙醇固定或福尔马林固定（福尔马林固定后经水洗并转入乙醇保存），随后带回实验室处理。样本分析工作在法国布列塔尼中心法国海洋开发研究院（Ifremer）深海环境实验室（LEP，Laboratoire Environnement Profond；https://wwz.ifremer.fr/deep_eng/）以及日本海洋研究开发机构（Jamstec）X-STAR研究所（https://www.jamstec.go.jp/xstar/e/）开展。本数据集的分析结果已在BioRxiv平台发布（https://doi.org/10.1101/2021.09.10.456763），目前正在《Ecology & Evolution》期刊审稿中。
本数据集包含两个文件：一个为数据文件，另一个为术语描述文件（涵盖所有测量指标及元数据）。
