Bamber (1990)

The feeding rate of ~1cm oysters (Crassostrea gigas) grown for 30 days under normal and reduced pH conditions was determined by measuring the "pseudofaecal production" -- the fine particulate material remaining in the experimental sea water at the end of the experiment. Reduced pH values were obtained by the addition of Analar sulphuric acid to filtered sea water.

Lannig et al. (2010)

Pacific Oysters (Crassostrea gigas) were grown for 22 days in reduced pH seawater. Control pH was 8.07 and experimental pH was 7.68. CO2 was bubbled into the experimental tanks to reach the desired pH.

Lannig et al. (2010)

Pacific Oysters (Crassostrea gigas) were grown for 22 days in reduced pH seawater after which they were exposed to acute warming (+5C) for ~12 hours. Control pH was 8.07 and experimental pH was 7.68. CO2 was bubbled into the experimental tanks to reach the desired pH.

Lannig et al. (2010)

Pacific Oysters (Crassostrea gigas) were grown for 22 days in reduced pH seawater after which they were exposed to acute warming (+5C) for ~12 hours, followed by an additional warming of 5C for 48 more hours. Control pH was 8.07 and experimental pH was 7.68. CO2 was bubbled into the experimental tanks to reach the desired pH.
