Arianna Martini is a researcher at CREA Zootechnics and Aquaculture.
Her main activity is the creation of Life Cycle Assessment models for the evaluation of potential environmental impacts associated to aquaculture production activities. In particular, his work has focused on Italian shellfish farming and on the potential role of shell formation as a carbon sink.
Ecosystem services of mussel farming: when potential carbon sequestration is possible
Among the ecosystem services provided by mussel farming, the carbon sequestration that occurs during shell formation is scientifically debated.
The shell is formed through the reaction between a calcium ion and two molecules of dissolved carbon dioxide.
This leads to the formation of calcium carbonate (the shell) and the release of a carbon dioxide molecule. As many local physico-chemical parameters affect the ability of mussel farming to act as a carbon sink, these impacts of mussel farming should be considered as locally as possible.
