Marine calcifiers exhibit mixed responses to CO2-induced ocean acidification

Eighteen marine species exposed to ocean acidification conditions for 60 days exhibited a wide range of responses. Ten of the 18 species were affected negatively with lower rates of net calcification and, in some cases, net loss of shell. Those species included temperate corals, pencil urchins, hard clams, conchs, serpulid ...

Ocean acidification and/or warmer temperatures may affect immune response, parasite abundance and diversity, and bacterial infection of blue mussels. (Laboratory study)

Ocean warming, more than acidification, reduces shell strength in a commercial shellfish species during food limitation

After six months exposure, warmer temperatures, but not ocean acidification, significantly reduced the shell strength of blue mussels, which were fed for a limited period of only 4-6 hours per day. The rising temperatures seemed to affect shell strength indirectly, as the mussels apparently re-allocated energy from shell formation to ...

Food supply and seawater pCO2 impact calcification and internal shell dissolution in the blue mussel Mytilus edulis

Blue mussels from the Baltic Sea grew less when raised for seven weeks under ocean acidification conditions and with limited food algae. Corrosion of the internal shell surface occurred at a range of ocean acidification levels when food supply was low. When food supply was high, corrosion occurred only in ...

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 ...

Food availability outweighs ocean acidification effects in juvenile Mytilus edulis: Laboratory and field experiments

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 ...

Moderate seawater acidification does not elicit long-term metabolic depression in the blue mussel Mytilus edulis

Shell growth of blue mussels from the Baltic Sea decreased under ocean acidification conditions. Data suggest that the reduced shell growth under severe acidification did not result from metabolic depression but from increased cellular energy demand and nitrogen loss. (Laboratory study)
