ABSTRACT
Carbon sequestration is an important strategy in combating rising carbon dioxide concentration in the atmosphere. There is much attention is given towards increasing the soil carbon sequestration potential and adopting proper management practices Soil is the largest terrestrial carbon sink which contains 1100-1600 Pg. Most of the added feeds end up accumulating within the aquaculture systems or are being discharged into adjacent bodies of water. Aquaculture is classified as an extensive, semi-intensive and intensive culture based on various management practices adopted. Biochar is the carbonaceous product obtained by the thermal degradation of organic materials in the absence of oxygen. Biochar’s climate-mitigation potential primarily stems from its highly recalcitrant nature towards chemical and microbial oxidation and will persist in soil for hundreds to thousands of years. The ability of microalgae to grow heterotrophically is significant and important because this allows microalgae to sequester organic carbons present in wastewaters, which can eventually emit to the atmosphere if broken down by bacteria.
