“…GHG emissions from agricultural land use contributed 19-20% to global GHG emissions, including those from chemical fertilizer and land preparation and intensive tillage (Rahman et al 2021). Aquaculture ponds stocked with freshwater bream (Megalobrama amblycephala) exhibit GHG emissions and greenhouse effect potential of 15.86 t CO 2 /hm 2 , suggesting their ability to contribute to global warming (Zhu et al 2016). Changing climate is a vital social issue which can be managed by the combination of reduced emissions and mitigation strategies by enhancing natural carbon (C) storage in the ecosystem, i.e., biosequestration.…”

In an aquaculture system, estimates were made of soil organic carbon content, carbon burial rate, soil structure and algal productivity with the intention of examining the synergistic effects of both greenhouse gas (GHG) induced temperature and manure-driven carbon reduction potentials in sediments that depend on productivity as well as tilapia spawning responses under greenhouse mimicking conditions during winter. Different manure treatments such as cattle manure and saw dust (T1); poultry droppings and saw dust (T2); vermi-compost and saw dust (T3); mixture of cattle manure, poultry droppings, vermi-compost and saw dust (T4); iso-carbonic states maintained with vermi-compost (T5); and with poultry droppings (T6) were applied three times (frequency of application) in the tank during the course of investigation. Different parameters like soil organic carbon, carbon burial rate, algal productivity and water quality were examined in aquaculture system. GHG effect impacted on the enhanced carbon reduction potential (44.36-62.36%) which was directly related with soil organic carbon (38.16-56.40 mg C/g) dependent carbon burial rate (0.0033-0.0118 g/cm 2 per 100 days). Average carbon burial rates for different manure treatments at GHG impacted temperature (0.0071 g/cm 2 per 100 days) was as high as 27.90% than at ambient air temperature (0.0054 g/cm 2 per 100 days). Residual carbon or sink in soils has been increased by 8.49 to 43.11% in different treatments or 23%, on an average attributed to almost 6 °C rise in GHG mediated atmospheric temperature. The low carbon footprint potential in different treatments was conspicuous inside the polyhouse (maximum 62.36%) due to greenhouse driven temperature compared. As a positive impact of the study, breeding of tilapia occurred where in T3 100% survival occurred in close polyhouse and also exhibited maximum carbon burial rate. In this study it has been observed that one degree rise in atmospheric temperature resulted in a ~ 4% rise in residual carbon in the experimental tank. However, future work can be conducted on other different treatments and large scale application. Highlights• Raised temperature impacted enhanced decomposition of manure.• Synergistic effects of temperature and GHG increase the primary productivity.• Simulated mesocosm induced the spawning of fish tilapia during winter. • Carbon burial rates at GHG impacted treatments were 27.90% higher.• Carbon reduction potential of soil was enhanced by about 23% due to GHG effect.
