Greenhouse Emissions From Aquaculture

摘要

To quantify the carbon dioxide and methane fluxes in tropical earthen ponds, the authors used freshwater prawn farming managed according to different strategies as a model. Ponds with both nighttime aeration and artificial substrates released an average 3.3, 2.0 and 1.5 times more carbon dioxide than traditional ponds or those with aeration or substrates alone, respectively. The absorption of carbon dioxide occurred only in ponds using night aeration. Methane was released in the day and night.
