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.
