Respiration and calcium carbonate (CaCO(3)) production by the farmed short-neck clam Ruditapes philippinarum were calculated to assess their importance as carbon dioxide (CO(2)) sink/source in a lagoon of the Po Delta River (Italy). Biomass and calcimass were established by monthly harvests during a 1-year period (2009). The ratio of CO(2) released to CaCO(3) precipitated was calculated as a function of the near-bottom temperature. From our estimates, R. philippinarum sequestered [Formula: see text] for shell formation, but the CO(2) fluxes due to respiration and calcification resulted 22.7 and 5.56 [Formula: see text] , respectively. Clam farming seems therefore to be a significant additional source of CO(2) to seawater.
养殖菲律宾蛤仔（Ruditapes philippinarum）的呼吸作用和碳酸钙（CaCO(3)）产量的计算，以评估其在意大利波河三角洲泻湖作为二氧化碳（CO(2)）汇/源的重要性。在一年的时间（2009 年）内，通过每月的收获来确定生物量和钙存量。根据近底温度计算 CO(2)释放与 CaCO(3)沉淀的比值。根据我们的估计，R. philippinarum 为壳形成固定了 [Formula: see text]，但由于呼吸作用和钙化作用导致的 CO(2)通量分别为 22.7 和 5.56 [Formula: see text]。因此，蛤仔养殖似乎是海水的一个重要的额外 CO(2)来源。
