To study the effects of Ocean Acidification and Warming on the embryonic development of Atlantic herring (Clupea harengus), fertilized eggs were incubated to three temperatures (6-10-14°C) and two PCO2 (400 and 110 µatm) until hatch. At the 50% eye pigmentation stage, we measured whole-embryo oxygen consumption rates (MO2) and mitochondrial respiration (ETS and the relative contribution of Complex I and Complex II to it). At hatch, we measured hatching success, larval size and deformities.
