Ocean acidification conditions and warmer temperatures reduced the survival, development, growth, and lipid synthesis of hard clam and bay scallop larvae. During the juvenile life stages, ocean acidification negatively affected juvenile eastern oysters and bay scallops, but not hard clams. Larvae were substantially more vulnerable to ocean acidication than juveniles ...

Blue mussels from the Kiel Fjord (Baltic Sea), where seawater pH tends to be low, were able to maintain growth rates when exposed to ocean acidification conditions (pH 7.7). in addition, juvenile mussels in the fjord settle mostly in summer when pH is lowest. The findings suggest that mussels may ...

Blue mussels grew and calcified 7 times faster in the Kiel Fjord (Baltic Sea), where low pH (ocean acidification) conditions prevailed, than at an outer fjord site where pH levels were higher In addition, the mussels were able to outcompete barnacles at the inner fjord, low pH site. Thus, blue ...

Hypoxia and acidification have additive and synergistic negative effects on the growth, survival, and metamorphosis of early life stage bivalves

In larval scallops,ocean acidification (pH 7.4–7.6) reduced survivorship by more than 50 percent. Low-oxygen water inhibited growth and metamorphosis. When exposed to both low oxygen and ocean acidification at the same time, scallops fared worse than under either one by itself. In early life stage clams, low oxygen led to 30 ...

Ocean acidification caused Eastern oysters and hard shell clams to accumulate more metal pollutants, which affected their physiology. (Laboratory study)

Blue mussels and ocean quahogs from the Baltic Sea appeared to tolerate wide ranges of seawater temperature and ocean acidification over a period of 13 weeks. (Laboratory study)

Immunomodulation by the interactive effects of cadmium and hypercapnia in marine bivalves Crassostrea virginica and Mercenaria mercenaria

Ocean acidification increased the negative effects of cadmium pollution on the immune systems of quahogs and eastern oysters, potentially making them more vulnerable to pathogens and disease. (Laboratory study)

Interactive effects of elevated temperature and CO2 levels on energy metabolism and biomineralization of marine bivalves Crassostrea virginica and Mercenaria mercenaria.

When quahogs and eastern oysters were exposed to a combination of warmer temperatures and ocean acidification for 15 weeks, shell hardness decreased in both species. By itself, ocean acidification had a small effect on the physiology and metabolism of both species, but it improved survival in oysters. (Laboratory study)
