Hatching success, survival and growth in northern stock black sea bass reared at contrasting pCO2 conditions in laboratory experiments conduced with embryos from adults collected in Long Island Sound in 2022

We experimentally examined early life CO2-sensitivities of northern stock black sea bass (Centropristis striata), an ecologically and economically important fish that seasonally migrates from offshore overwintering grounds to coastal feeding and nursery areas. We produced embryos from wild spawners and reared them until 10 days post hatch (dph) at three contrasting pCO2 levels (~400, ~2200, ~3000 µatm), finding no statistical effects of pCO2 on hatching success (~25%) or survival to 10 dph (~11%). At the extreme pCO2 level, surviving larvae were 1.2× larger and grew 55% faster compared to control pCO2 conditions. This dataset contains hatching success, survival, and growth data from these experiments.

本研究针对北部种群黑石斑鱼（Centropristis striata）的早期生命阶段二氧化碳分压（pCO2）敏感性开展实验探究，该鱼种兼具重要生态与经济价值，会季节性地从近海越冬场洄游至近岸索饵与育幼区域。本研究获取野生亲鱼所产的受精卵，并在三个梯度差异显著的二氧化碳分压（pCO2）水平（分别约为400、2200、3000 µatm）下将其饲养至孵化后10天（days post hatch, 简称dph），结果发现二氧化碳分压对孵化成功率（约25%）及孵化后10天的存活率（约11%）均无统计学显著影响；在最高二氧化碳分压组中，存活幼鱼的体型较对照组大1.2倍，生长速率较对照组快55%。本数据集包含本实验产生的孵化成功率、存活率与生长相关数据。
