The data of the article "Synergistic effect of abalone and macroalgae on carbon storage in a co-culture ecosystem"

Bivalves accelerate atmospheric carbon dioxide absorption at low and medium stocking densities, while the role of gastropods fed with macroalgae remains unclear. Here, we used mesocosm experiments were to quantify the carbon storage potential of the gastropod abalone in monoculture and in co-culture with the macroalgae Gracilaria.

Results showed that abalone monoculture acts as a source of atmospheric carbon dioxide, whereas the co-culture functions as a carbon dioxide sink. This transformation arose from higher net community productivity and the greater quantity of recalcitrant carbon in the co-culture system. When co-cultured, abalones and macroalgae exhibited synergistic effects on carbon storage due to abalones’ fertilization effect and the interaction between micro- and macroalgae.
