Mytilus edulis growth rates from a three-month mesocosm experiment, Sylt, 2022

This dataset contains individual-level measurements of the blue mussel Mytilus edulis collected during a controlled mesocosm experiment at Sylt, Germany. Data were collected over a three-month period from 2 April 2022 to 27 June 2022. The experiment comprised twelve mesocosms, with four maintained at ambient temperature, four maintained at +1.5°C above ambient, and four at +3 °C above ambient. Observations include shell length, shell-length growth rates, and multiple biomass fractions, including total wet weight, wet tissue mass weight, shell-free dry weight, and ash-free dry weight, from which weight-based growth rates were calculated. All measurements were obtained using standard, traceable laboratory and field instruments. The dataset documents individual-level growth responses of M. edulis under controlled warming conditions and provides a reproducible resource for studies on physiological responses of coastal bivalves to temperature changes.

本数据集包含于德国叙尔特岛（Sylt）开展的受控中宇宙实验（mesocosm experiment）中采集的蓝贻贝（Mytilus edulis）个体水平测量数据。数据采集周期为2022年4月2日至2022年6月27日，历时三个月。本次实验共设置12个中宇宙实验单元，其中4个维持环境温度水平，4个维持较环境温度高1.5℃的升温条件，剩余4个维持较环境温度高3℃的升温条件。观测指标涵盖壳长、壳长生长速率，以及总湿重、软组织湿重、去壳干重与无灰干重（ash-free dry weight）等多种生物量组分，并基于上述组分计算得到了基于体重的生长速率。所有测量均采用具备可溯源性的标准实验室与野外仪器完成。本数据集记录了蓝贻贝（Mytilus edulis）在受控升温条件下的个体生长响应，可为沿海双壳类对温度变化的生理响应相关研究提供可复现的学术资源。
