摘要： In this study, we assess the greenhouse gas emissions and greenhouse effect potential of a Wuchang bream (Megalobrama amblycephala) aquaculture. We used the 'static opaque chamber-gas chromatography method' to determine in situ emissions of greenhouse gases in the 3-month growing season (CO2, CH4, and N2O) from bream culturing ponds. We detected emissions of all three gases from the ponds, with CO2 emission far exceeding the other gases in the 3-month growing season (CO2 = 278.54 +/- 36.41 g/m(2), CH4 = 23.73 +/- 5.27 g/m(2), and N2O = 1.69 +/- 0.32 g/m(2)). We calculated that in one growing season this ecosystem would have a total emission of CO2 equivalent of 15.86 t CO2/hm(2), indicating its ability to contribute to global warming via the greenhouse effect.
