Studies suggest that ocean acidification (OA) adversely affects various biological processes in marine organisms, including reproductive capacity, larval development, biocalcification, metabolism, immune and antipredator responses, and behavioral changes. Mollusks, particularly the classes Gastropoda and Bivalvia, are notably sensitive to OA. This chapter also explores the disruption of reproductive processes in mollusks due to elevated CO2 levels, focusing on hatching, fertilization, and larval development, and discusses how genetic expression analysis provides insights into the reproductive impacts of OA on mollusks. Finally, it addresses the adaptive reproductive strategies of mollusks in response to acidification pressures and the cultivation of stress-resistant varieties to cope with changing marine environmental conditions.
