Increase of Carbon Dioxide Affects Oysters

oysterOcean acidification tremendously affects oyster growth and survival. Animals like clams, mussels, oysters, and other bivalves construct calcium carbonate shells by using raw materials found in the sea. Due to an increase of carbon dioxide, oysters struggle to build shells. Oyster larvae have difficulty obtaining sufficient amounts of energy to build their shells. This is due to oceans obtaining more carbon dioxide. The increase causes a response which decreases the water’s pH. This could potentially be harmful to the shells. Also, it changes the accessibility of the compounds required to make shells. This is a major issue because the energy the oyster larvae needs to build shells gradually increases and the disappearance of carbon dioxide in the water also rises. This is a possible explanation for the decline of the oyster populations.
