Abstract: In response to the challenges of global climate change and to help my country achieve the “Dual Carbon” goals, the aquaculture industry is accelerating its green and low-carbon transformation. This paper systematically explains the innovative application of probiotic technology in the field of carbon emission reduction in aquaculture systems and its mechanism of action. It is mainly reflected in three dimensions:(1)In terms of carbon input regulation, by improving feed utilization, improving host health and reducing drug use, regulating water quality and reducing energy input for water quality maintenance, the system carbon input source is reduced;(2)In terms of carbon emission inhibition, the host ammonia nitrogen emissions are reduced through metabolic regulation pathways, the activity of methanogens is inhibited by regulating the microecology, and the mineralization of organic matter is accelerated.(3)In the carbon sequestration enhancement link, the growth of large algae and filter-feeding shellfish is promoted through nutrient recycling, and a multi-level carbon sink system is constructed. The comprehensive application of compound probiotics can effectively reduce the carbon footprint and carbon emission intensity of the aquaculture system, providing an important theoretical basis and technical support for the low-carbon transformation of the aquaculture industry.
