水田単作から魚類との共作への転換は農家収入向上の一般的戦略である。本研究では、高価値種であるスッポンとの共作（RT）が温室効果ガス排出と経済性に与える影響を評価した。RTは米収量を有意に増加させないものの、スッポン販売による追加収入で純利益を増加させた。GHG排出への影響は農場により異なり、一方の農場では総CH4排出を36.5%削減し、総GHG排出を27.7%削減した。RTは経済的利益を高めつつGHG排出を削減できる可能性を示す。

Converting rice monoculture to co-culture with fish is a common strategy to increase farmers' incomes. This study evaluated the effects of rice–Chinese soft-shell turtle co-culture (RT) on economic benefits and greenhouse gas emissions. RT did not significantly increase rice yield but provided additional income from turtle sales, increasing net profits. GHG emission responses varied between farms; at one farm, RT reduced total CH4 emissions by 36.5% and total GHG emissions by 27.7%. RT can enhance economic benefit while lessening total GHG emissions.

📄 Abstract（原文）
Converting conventional rice monoculture to co-culture with fish is a common strategy to increase farmers’ incomes. The Chinese soft-shell turtle is a typical high-value species for paddy co-culture, but the effects of the co-culture system (RT) on greenhouse gas emissions (GHG) are poorly understood. This study evaluated the impacts of RT on economic benefits and greenhouse gas emissions. Our results showed that RT co-culture did not significantly increase rice yield, but it provided additional income from turtle sales, increasing net profits. GHG emission responses to RT differed between the two farms. In farm 1, RT increased CH4 emissions from the rice-cultivated area but decreased them from the turtle culture area, resulting in no net effect on total CH4 emissions. The reduction of CH4 emissions in the turtle culture area was associated with lower DOC content and reduced methanogenic gene mcrA abundance. In farm 2, RT reduced CH4 emissions from both areas, lowering total CH4 emissions by 36.5%, which was linked to less water flooding and higher methanotrophic gene (pmoA) abundance. Total N2O emissions were not significantly affected by RT at either farm. RT increased indirect GHG emissions, but these accounted for only 7.2–16.9% of total emissions. Overall, RT reduced total GHG emissions by 27.7% at farm 2, with no significant change at farm 1. These findings suggest that RT can enhance economic benefit while lessening total GHG emissions.
