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 ...
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)
Calcification rates of the blue mussel and the Pacific oyster decline with increasing ocean acidification. Mussel and oyster calcification may decrease by 25 percent and 10 percent, respectively, by the end of the century. (Laboratory study)
The effects of ocean acidification on the growth and shell production by juvenile and adult shelled molluscs are variable among species and even within the same species, precluding the drawing of a general picture. This is, however, not the case for pteropods, with all species tested so far, being negatively ...
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)
Sea stars collected in Nova Scotia, Canada, grew more slowly under ocean acidification conditions, and their growth rate decreased further with a warmer temperature. In contrast, blue mussel grew more quickly with no response to temperature within the tested range. Predation of sea stars on mussels, measured as per-capita consumption ...
When larvae of blue mussels were kept in ocean acidification conditions predicted for 2100 (pH 7.6) there was no marked effect on fertilization, development, abnormalities, or feeding. However, although the mussel larvae were able to form shells, after two months of exposure they were 28 percent smaller than larvae raised ...
Blue mussels exposed to highly acidified seawater for sixty days were able to protect their body tissues involved in reproduction, digestion, and respiration. However, the physiological defenses take energy away from other life processes, meaning that long-term exposure to ocean acidification may result in reduced growth and health of blue ...
Blue mussels in pH 7.1 seawater for 44 days had reduced shell growth, and those in pH 6.8 virtually stopped growing. In less acidified water—pH 7.4 or 7.6—shell growth was not significantly reduced.
