Fecundity of the common sea star Asterias rubens after exposure to two temperature and food ration conditions

this dataset reports the results of an experiment on the impacts of ocean warming and food ration on the fecundity of the sea star asterias rubens. males and females were acclimated for 26 weeks (from october 2nd 2023 to april 1st 2024 included) either to +0°c or +3°c compared to the usual seasonal temperature, and either to 1 or 3 mussels per sea star twice a week, in a controlled laboratory environment. biometric parameters (body weight, arm length, pyloric caeca weight, gonad weight, pyloric index, gonadosomatic index), gametes concentration (number of gametes per gram of gonad) and fecundity (number of gametes per individual) were assessed at the end of the acclimation period.data included are:1) calendar: information on the photoperiod and the temperature applied at each experimental week.2) live_mussels: numbers of uneaten mussels from the previous feeding session.3) biometric_parameters: biometric parameters (body weight, arm length, pyloric caeca weight, gonad weight, pyloric index, gonadosomatic index) measured for each sea star at the end of the experiment.4) female_fecundity: gamete concentration and individual fecundity of females at the end of the experiment.5) male_fecundity: gamete concentration and individual fecundity of males at the end of the experiment.

本数据集报告了一项关于海洋升温与食物配给对海星 Asterias rubens 繁殖力影响的实验结果。实验中，雄性和雌性海星分别于2023年10月2日至2024年4月1日期间，适应了相较于常规季节温度的+0°C或+3°C的环境条件，以及每周两次，每只海星摄入1或3只贻贝的饲养方案。在实验室的严格控制环境下，对海星进行了为期26周的适应性驯化。在驯化期末，评估了生物计量参数（体重、臂长、幽门盲囊重量、生殖腺重量、幽门指数、生殖腺体重指数）、配子浓度（每克生殖腺中的配子数量）以及繁殖力（每只个体的配子数量）。数据内容包括：1）日历：每个实验周的光周期和所应用的温度信息。2）活贻贝：上一饲养会中未被摄食的贻贝数量。3）生物计量参数：在实验结束时，对每只海星测量的生物计量参数（体重、臂长、幽门盲囊重量、生殖腺重量、幽门指数、生殖腺体重指数）。4）雌性繁殖力：实验结束时雌性配子浓度及个体繁殖力。5）雄性繁殖力：实验结束时雄性配子浓度及个体繁殖力。
