Figure 3:

Viable hatch of Atlantic herring (Clupea harengus). Values are reported as mean ± SEM. Panel A: hatching success as percentage of fertilized eggs that hatch. Open bars: control PCO₂ (400 μatm), solid bars: high PCO₂ (1100 μatm). Panel B: Larval malformations as percentage of hatched larvae. Open bars: control PCO₂ (400 μatm), solid bars: high PCO₂ (1100 μatm). Different letters indicate statistical differences (P < 0.05) between temperature treatments, * indicates significant differences (P < 0.05) between CO₂ groups at the same temperature.
