Bamber (1987)

Mean dry flesh weight of large (mean shell length 7.8 mm) clams (Venerupis decussata) grown for 8 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. Throughout the experiment seawater temperatures fluctuated between 11.0 and 11.7C. Reduced pH values were obtained by the addition of Analar sulphuric acid to filtered sea water.
