Abstract
The kinematics of swimming behavior of Atlantic herring larvae cultured under three p CO 2 conditions (control — 370, medium — 1800, and high — 4200 μatm) were extracted at 34 days post-hatch (dph) from swim path recordings obtained using silhouette video photography. The swim paths were analyzed for move duration, speed and length, stop duration, and horizontal and vertical turn angles to determine the effects of elevated p CO 2 on fish larval behavior. The swimming kinematics and occurrence of S-postures in Atlantic herring larvae that had survived to 34-dph were unaffected by extremely elevated levels of seawater p CO 2 , indicating that at least some larvae in the population are resilient to ocean acidification . • We analyzed the behavior of herring larvae grown under elevated p CO 2 conditions. • Data on kinematics of the swim paths and display of feeding postures are reported. • Both swimming and display of feeding postures were unaffected by elevated p CO 2 .
