The ocean provides us with more than 20％ of the protein source (half of which comes from aquaculture), and stores more than 60％ of the carbon sink in the earth. The world’s largest carbon storage does not come from the forest that people are familiar with, but from the vast ocean and deep seabed. The use of Blue Carbon Mixed Aquaculture in the farming process can establish friendly aquaculture and achieve carbon storage, carbon fixation, and cleaning farm pond substrate at the same time. With our technology, in addition to reaching the purpose of carbon storage, carbon fixation and friendly farming, we also provide our partners with aquaculture carbon database storage and carbon reduction methods based on blockchain technologies.
