- Effects of Simulated Ocean Acidification on the Activity, Escape Response, and Muscle Physiology of Marine Threespine Stickleback (Gasterosteus aculeatus). Yoon, Gwangseok R Khodikian, Elissa Ren, Gary J Porteus, Cosima Animals Smegmamorpha Seawater Hydrogen-Ion Concentration Carbon Dioxide Escape Reaction Muscles Oceans and Seas Muscle, Skeletal Ocean Acidification Rapidly increasing anthropogenic CO can impose physiological challenges for fish species that are thought to be tolerant. We tested the hypothesis that elevated pCO will affect the routine activity and escape response by affecting energy metabolism and/or the muscle physiology of coastal fish. We exposed threespine stickleback (Gasterosteus aculeatus) to pCO of ~ 700 µatm (pH 7.9 representing current levels), ~ 1400 µatm (pH 7.6 representing upwelling events) and ~ 3500 µatm (pH 7.3 representing a future predicted scenario for coastal areas) for 2 weeks. Baseline activity was significantly higher in fish exposed to 1400 µatm compared to the control at both sampling points, while the escape response was lower (p 0.05), but lactate dehydrogenase activity was significantly higher at 3500 µatm compared to control fish after the first week (p
