Impact of ocean acidification on the biology of marine bivalves

Abstract

Ocean acidification, resulting from increased atmospheric CO₂ levels, poses a significant threat to marine ecosystems, particularly to shell-forming organisms such as marine bivalves. This review synthesizes current knowledge regarding the impacts of ocean acidification on bivalves, including oysters, clams, and mussels, focusing on their physiology, development, and ecological interactions. Acidification impairs shell formation, disrupts energy metabolism, alters feeding and respiration patterns, and inhibits the growth and recruitment of larvae. These changes can destabilize bivalve populations and impair the ecosystem services they offer, such as water filtration, habitat creation, and support for fisheries and aquaculture. The report discusses potential strategies to mitigate the impacts of climate change, including the reduction of carbon emissions, selective breeding, and habitat management. This underscores the necessity of interdisciplinary research to comprehend the long-term impacts of climate change and to promote sustainable resource management that benefits the environment.
