, which respectively substantially increased by 102% and 271% in moderate- and high-intensity aquaculture ponds, establishing them as potent estuarine DCF hotspots. Aquaculture reclamation enriched carbon-fixing microorganisms, and shifted their compositions from a "generalist" (characterized by aerobic and versatile taxa) to a "specialist" (dominated by strictly anaerobic taxa) type. This shift indicated a fundamental ecological change driven by habitat anaerobiosis, triggering a microbial energy reallocation from growth to maintenance. The proposed "aquaculture reclamation-induced thermo-carbon pump" concept describes how anthropogenic inputs enhance coastal carbon sequestration and its thermal sensitivity, representing a positive feedback mechanism in carbon-climate interactions.
