Effect of heatwaves on the fish Sparus aurata from the Iberian Peninsula: molecular data

Predicting responses of marine organisms to global change requires eco-physiological assessments across the complex life cycles of species. Here, we experimentally tested the vulnerability of a demersal temperate fish (Sparus aurata, collected from an aquaculture in Ayamonte, Spain) to long-lasting heatwaves, on larval, juvenile and adult life-stages. Fish were exposed to simulated coastal (18 ºC), estuarine (24 ºC) summer temperatures, and heatwave conditions (30 ºC) and their physiological responses were assessed based on cellular stress response biomarkers (heat shock protein 70 kDa, total ubiquitin, catalase, glutathione-S-transferase, superoxide dismutase, lipid peroxidation). Two different formats of the same data-set are provided.

预测海洋生物对全球变化的响应，需针对物种复杂的生活史开展生态生理学评估。本研究通过实验，评估了底栖温带鱼类金头鲷（Sparus aurata，采集自西班牙阿亚蒙特（Ayamonte）的一处水产养殖场）在仔鱼、稚鱼以及成体阶段对持续热浪的脆弱性。实验中将该鱼类分别置于模拟的沿岸（18℃）、河口（24℃）夏季水温以及热浪环境（30℃）中，并基于细胞应激响应生物标志物（70kDa热休克蛋白、泛素总量、过氧化氢酶、谷胱甘肽S-转移酶、超氧化物歧化酶、脂质过氧化水平）对其生理响应进行了评估。本数据集提供两种不同的存储格式。
