摘要： Sustainable "blue food" has raised new demands and challenges for aquaculture technology. Based on a "cradle to gate" life cycle assessment (LCA) covering aquaculture and the upstream stages, this study aims to analyze and evaluate the carbon footprint (CFP) of shrimp Litopenaeus vannamei farming which is currently booming in China, using the cases of four recirculating aquaculture systems (RAS) and two culture modes. Respiration carbon emission by cultured animals was also estimated in order to compare the biological greenhouse gas (GHG) contribution. The results showed that the CFP of shrimp culture ranged from 13769.32 to 14860.87 kgCO2-eq/t. Electricity consumption was the main contributor to CFP, accounting for 50.6-53.2 %, followed by biological carbon emissions (17.6-19.3 %), and feed (15.9-18.1 %) which was mostly contributed by the production of raw materials (2278.17 kgCO2-eq/t). Infrastructure was the fourth (9.52-11.47 %) CFP generator, mostly contributed by building materials (1100.26-1399.47 kgCO2-eq/t). Since the use of photovoltaic power (572.52 kgCO2-eq/t) and other green energy can greatly reduce aquaculture CFP, compared to traditional coal-based energy source (7340.01 kgCO2-eq/t), we believe that RAS can take advantage of more possibilities in site selection and make use of a full range of clean energy. By improving the efficiency of space use and waste water purification, and optimizing the farming mode and productivity, RAS may achieve the dual purpose of increasing production and reducing carbon emission, which is in line with sustainable development of "blue food".
