Carbon dioxide and methane fluxes from feeding and no-feeding mariculture ponds.

???displayArticle.abstract???
The CO2 and CH4 fluxes at the water-air interface were measured in shrimp (Marsupenaeus japonicus) monoculture ponds (S) with feed supply and shrimp-sea cucumber (Apostichopus japonicus) polyculture ponds (SS) without feed supply. During farming seasons of the whole year, cumulated CO2-C fluxes were -5.69 g m(-2) (S) and 11.23 g m(-2) (SS), respectively. The cumulated CO2 emissions from S and SS did not differ significantly. The cumulated CH4-C emissions from S (0.57 g m(-2)) were significantly higher than those from SS (0.068 g m(-2)). S absorbed C from the atmosphere with a mean absorption rate of -5.12 g m(-2), whereas SS emitted C to the atmosphere with a mean emission rate of 11.30 g m(-2). Over 20-year horizon, the compressive global warming potentials (cGWPs) were 33.55 (S) and 47.71 (SS), respectively, indicating both feeding and no-feeding mariculture ponds could promote global warming.
