Xunshan Group, an aquatic product company in Weihai, a coastal city in Shandong Province, has employed a three-layered ecological breeding model. The upper layer grows algae such as kelp, the middle layer breeds shellfish such as abalone and scallops, and the lower layer raises fish and sea cucumbers.
With this integrated multi-trophic aquaculture approach, multiple species are cultivated in proximity to create a more sustainable and balanced aquaculture system.
Algae and other marine organisms are vital in capturing and storing carbon through biological carbon sequestration. Through photosynthesis, algae absorb carbon dioxide from the atmosphere and transform it into organic compounds.
