Raw data concerning the carbonate system and the sensory behaviour of juvenile Dicentrarchus labrax in response to mechano-acoustic and visual predator cues under ocean warming and acidification

This data set is linked to a study that sought to investigate whether a mid-term 92-days exposure to warming and/or acidification alters the response to visual or mechano-acoustic predator cue in the European sea bass Dicentrarchus labrax when it comes to detect and avoid simulated avian predator cues. Juveniles, aged between 283 to 316 days post hatching, were challenged in separate behavioural trials to assess their reaction facing either a shadow (visual cue) or a falling object (mechano-acoustic cue). These cues were intended to mimic an overflying bird shadow or a bird swoop attack, respectively. 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, which is also shown in the 3rd tab. Total body length (in cm, from the nose tip to end of caudal fin) was measured upon arrival in a sample of 74 alive individuals (5th tab) or in 165 dead individuals after the visual tests (6th tab) and in 201 dead individuals after the mechano-acoustic tests (7th tab). Data sets for both the visual tests (6th tab) and the mechano-acoustic tests (7th tab) were used to run the linear mixed-effects models.
