Ocean acidification and ocean warming (OAW) are simultaneously occurring and could pose ecological challenges to marine life, particularly early life stages of fish that, although they are internal calcifiers, have poorly developed acid-base regulation. This study assessed the effect of projected OAW on key fitness traits (growth, development and swimming ability) in European sea bass (Dicentrarchus labrax) larvae and juveniles. Starting at 2 days post-hatch (dph), larvae were exposed to one of three levels of PCO₂ (650, 1150, 1700 µatm; pH 8.0, 7.8, 7.6) at either a cold (15°C) or warm (20°C) temperature. Growth rate, development stage and critical swimming speed (Ucrit) were repeatedly measured as sea bass grew from 0.6 to ~10.0 (cold) or ~14.0 (warm) cm body length. Exposure to different levels of PCO₂ had no significant effect on growth, development or Ucrit of larvae and juveniles. At the warmer temperature, larvae displayed faster growth and deeper bodies. Notochord flexion occurred at 0.8 and 1.2 cm ... : Ucrit data larvae sea bassUdrict data measured in the European sea bass larvae from 17 to 56 days-post-hatch (dph) reared at a combination of two temperature (15°C and 20°C) and three PCO2 levels (ambient, ~1000 µatm and ~1700µatm).ucrit4.csvUcrit data juvenile sea bassUcrit data measured in the European sea bass juvenile reared under a combination of two temperature (15°C and 20°C) and two PCO2 levels (ambient, ~1700µatm)ucrit_juv.csv ...
