Methane and nitrous oxide have separated production zones and distinct emission pathways in freshwater aquaculture ponds

•Extensive freshwater aquaculture ponds are a CH4 hotspot but emit minor N2O;•Ebullition is the primarily pathway for CH4 transport;•N2O is produced in water column and can diffuse downwards to be consumed;•Carbon supply and redox condition control the spatiotemporal variations of N2O flux. Aquacult...
