Interests in carbon markets worldwide have increased significantly due to the growing urgency of climate change mitigation, prompting a reassessment of nature-based solutions for reducing greenhouse gas (GHG) emissions. Wetland environments and forests have long been recognized as carbon sinks, but little is known about how aquaculture helps sequester carbon and how it may be included into carbon credit markets. With a focus on shellfish, seaweed, and integrated multi-trophic aquaculture (IMTA), this study examines the potential of aquaculture systems to sequester carbon. This study also examines how prepared various aquaculture systems are to take part in compliance and voluntary carbon markets. Through biological processes including carbonate shell formation, photosynthetic COâ‚‚ uptake, and sedimentary carbon burial, aquaculture can function as a blue carbon sink.
