Clam farming generates CO₂: A study case in the Marinetta lagoon (Italy)
2012
Mistri, Michele | Munari, Cristina
Respiration and calcium carbonate (CaCO₃) production by the farmed short-neck clam Ruditapes philippinarum were calculated to assess their importance as carbon dioxide (CO₂) 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 CO₂ released to CaCO₃ 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 CO₂ 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 CO₂ to seawater.
