The present study analyzed the inputs, outputs, and accumulation of carbon in ecological compartments of earthen ponds for the grow-out of Amazon river prawn (Macrobrachium amazonicum) and tambaqui fish (Colossoma macropomum) reared in monoculture and integrated multi-trophic aquaculture (IMTA) systems, using recycled hypereutrophic water. A completely randomized experiment was designed with four treatments and three replications: PM- monoculture with 30 prawn m⁻², FM- monoculture with 3 fish m⁻², IMTA- fish-prawn polyculture with 30 prawn m⁻² and 3 fish m⁻² reared free-swimming, POLY-CAGE- fish-prawn IMTA with 30 prawn m⁻² reared free-swimming and 40 fish m⁻³ in net-cages. Animals, rain, water, feed, soil, gases, total suspended solids, settleable solids, and accumulated sludge were collected throughout the experiment to determine their total organic and total inorganic carbon contents and to calculate the carbon budget. Results showed that much of the carbon accumulated as solid organic material (∼55 – 84%) and animal biomass (∼4 – 18%). The remaining carbon was discharged to receiving water bodies in the outlet water during harvesting (∼6 – 8%) or emitted as carbon dioxide (CO₂) and methane (CH₄) (∼1 – 5%). Feed management appeared to influence the major biological processes in the aquatic carbon cycle, such as photosynthesis and aerobic decomposition. All systems showed absorption of atmospheric CO₂ (∼529 – 782 kg C-CO₂ ha⁻¹) that was higher than the emissions (∼35 – 93 kg C-CO₂ ha⁻¹) and CH₄ (∼14 – 123 kg C-CH₄ ha⁻¹). Furthermore, all of the culture processes in the present study removed ∼1,000 to 2,000 kg Total Carbon ha⁻¹ from the inlet water, and thus, these systems can provide important ecosystem services. The high accumulation of carbon in the settleable solids (∼69% of outputs) and the adequate water quality maintained in the IMTA demonstrate the resilience of this grow-out system to high allochthonous inputs of organic matter as feed. An increased prawn density or the addition of a mud-feeder species to the culture may enhance the incorporation of carbon from settleable solids into harvested biomass, improving the efficiency of the systems.

本研究分析了在单一养殖和综合多营养水产养殖（IMTA）中饲养的亚马逊河虾（Macrobrachium amazonicum）和tambaqui鱼（Colossoma macropomum）养殖的土池生态区隔中碳的输入，输出和积累。）系统，使用回收的富营养水。设计了具有四个处理方法和三个重复的完全随机实验：30个大虾m ^-2的PM单种养殖，3个大鱼m ^-2的FM单种养殖，30个大虾m ^-2和3个大鱼m-的IMTA-鱼虾混养^{。 2尾}自由游泳，POLY-CAGE-鱼虾IMTA，其中30只虾m ^-2养成自由游泳，网箱中养鱼40米^-3。在整个实验过程中收集动物，雨水，水，饲料，土壤，气体，总悬浮固体，可沉降固体和累积的污泥，以确定它们的总有机碳和总无机碳含量，并计算碳预算。结果表明，大部分碳以固体有机物质（〜55 – 84％）和动物生物质（〜4 – 18％）的形式积累。收获期间，剩余的碳被排放到出水的接收水体中（约6 – 8％），或以二氧化碳（CO ₂）和甲烷（CH ₄）（〜1 – 5％）。饲料管理似乎会影响水生碳循环中的主要生物过程，例如光合作用和有氧分解。所有系统都显示出大气中的CO ₂（〜529 – 782 kg C-CO ₂  ha ^-1）的吸收量高于排放量（〜35 – 93 kg C-CO ₂  ha ^-1）和CH ₄（〜14 – 123 ）的吸收量kg C-CH ₄  ha ^-1）。此外，本研究中的所有培养过程均去除了约1,000至2,000 kg总碳ha ^-1从进水开始，因此这些系统可以提供重要的生态系统服务。IMTA中可沉积固体中碳的大量积累（约占产出的69％）和适度的水质证明了该成长期系统对高异源输入有机物作为饲料的适应力。对虾密度的增加或向培养物中添加泥浆添加物的种类可能会增强将可沉降固体中的碳掺入收获的生物质中，从而提高系统效率。
