Ocean Acidification & Fish Behavior

Excess carbon dioxide from land-use changes, the combustion of fossil fuels, etc. has increased the amount of CO2 in the atmosphere. The ocean absorbs a portion of the excess CO2. This process was once believed to be beneficial as it slowed global warming but caused a drop in the pH of the seawater, commonly known as ocean acidification (OA). Initial OA studies focused on the impact this would have on marine calcifiers (ex: corals, shelled organisms). The lowered pH impacts shell formation and development, and causes deformities in calcifying organisms. Only recently have researchers begun to investigate OA effects on marine fishes.
