Abstract

Small-scale aquaculture operation is increasing rapidly in the world, but its greenhouse gas (GHG) contributions are still poorly assessed. In this study, dissolved concentrations and fluxes of CO2 and CH4 were determined in three coastal shrimp ponds in southeastern China. The annual average CO2 an...
