摘要： Studies on aquaculture models currently focus on assessing single economic or ecological benefits, while the analysis of the combined economic and ecological benefits of different factory farming models has rarely been reported. Furthermore, there is a lack of comprehensive research on the combined effects of multiple farming models on the environment. Therefore, we used Meta-analysis to quantify and compare the economic and ecological benefits of different factory farming modes and their combinations under multidimensional conditions, including the Indoor super-intensive shrimp culture model (ISIC-S), Indoor super intensive biofloc shrimp culture (ISBIC-S), Indoor super-intensive recirculating shrimp culture (ISIRC-S), and the Indoor super-intensive fish culture model (ISIC-F). The results showed that the economic and ecological benefits of using a combination of multiple factory farming models were significantly increased by 38 % compared to a single factory farming model, with an 11 % increase in economic benefits and an 88 % increase in ecological benefits in a single benefit. Specifically, the economic and ecological benefits increased by 64.65 % for the combination of ISBIC-S, ISIRC-S and ISIC-F modes compared to ISIC-S. The combination of ISIRC-S and ISIC-F increased the economic and ecological benefits by 13.75 % compared to ISBIC-S. In terms of economic benefits, the cost structure of the four factory farming models was similar due to the similar farming technology, and the total cost of the combination of multiple factory farming models increased by only 6 %. However, due to the maturity of the farming technology, the ISIC-S model had the highest net profit of 182,778.75US$ ha- 1 as compared to the single model, which was better in terms of economic benefits. Regarding ecological benefits, the multiple factory model showed significant reduction in suspended solids compared to the single model. The analysis of bacterial diversity and carbon sink capacity indicated that the bacterial diversity and abundance in ISBIC-S and ISIRC-S modes were higher than that of ISIC-S, and the carbon emission per unit of production was highest in ISIC-F (1858.14 g kg- 1CO2), followed by ISBIC-S (1732.66 kg- 1CO2). In conclusion, adopting multiple synergistic factory farming models is a feasible and sustainable approach to enhancing economic returns while significantly improving the ecological environment. These findings provide a theoretical foundation for developing factory farming models that promote the sustainable development of aquaculture.
