This data set is linked to a study that sought to investigate whether a mid-duration exposure (92-days) to warming and/or acidification alters the response to visual or mechano-acoustic predator cues in the European sea bass Dicentrarchus labrax. Juveniles, aged between 283 to 316 days post hatching, were challenged in separate behavioural trials to assess their reaction facing either an overflying bird shadow (visual cue) or a bird swoop attack (mechano-acoustic cue). Abbreviations for the kinematic behavioural variables evaluated during the behavioural tests are available in the 1th tab. To follow the best practices of ocean acidification, the 2st and 3nd tabs show daily measurements of temperature and pH (in NIST scale). The 4rd tab shows weekly measurements of salinity, oxygen, total alkalinity, temperature and pH (in NIST and total scale) that were used to calculate the carbonate system parameters. Total body length (measured from the nose tip to end of caudal fin) was measured upon arrival in a sample of 74 individuals (5th tab) or in 165 individuals after the visual tests (6th tab) and in 201 individuals after the mechano-acoustic tests (7th tab). Data sets used to run the linear mixed-effects models for the visual tests or for the mechano-acoustic tests are shown in the 6th and 7th tabs, respectively.
