Introduction:
The Impact of Ocean Acidification on Shellfish Calcification
The health of the world's oceans is vital to the planet's overall well-being, as they play a crucial
role in regulating climate, supporting biodiversity, and providing resources and livelihoods to
millions of people worldwide. However, anthropogenic activities, particularly the burning of
fossil fuels, have led to increased carbon dioxide (CO2) emissions, resulting in the phenomenon
known as ocean acidification. This process involves the absorption of CO2 by seawater, leading
to a decrease in pH levels and alterations in the carbonate chemistry of the ocean.
Among the various marine organisms affected by ocean acidification, shell-forming organisms
such as shellfish are particularly vulnerable. Shellfish, including mollusks like oysters, clams, and
mussels, rely on calcium carbonate (CaCO3) to build and maintain their shells or exoskeletons.
As the acidity of seawater increases, it becomes more challenging for…
