At the end of May, World’s first self-propelled deep-sea aquaculture vessel with a pollution-free seawater exchange system was successfully launched in Jiangmen, South China’s Guangdong Province. The vessel measures 155.8 meters in length, 44 meters in width and 24 meters in depth, with a maximum draft of 20 meters. It also uses an advanced all-electric propulsion system, equipped with four sets of Weichai 16M55 2250kW marine gen set to provide all the power for the entire ship, like a pair of powerful "fins", allowing the ship to move freely in the bay area.

Unlike ordinary fishing vessels, the underwater section of the vessel is not a closed structure. Instead, it comprises 15 columns assembled into an “underwater palace.” By suspending fishing nets within this structure, 12 independent aquaculture chambers are created, enabling the simultaneous cultivation of multiple fish species and significantly diversifying the types of aquaculture possible.

Upon completion, the vessel is expected to produce 5,000 tons of fish annually, serving as a key contributor to ensuring “fish freedom” for local residents in the Guangdong-Hong Kong-Macao Greater Bay Area.  marking the start of a new era of China’s deep-sea aquaculture industry featuring the “technological ocean ranching” that integrates intelligent aquaculture practices with energy conservation, environmental protection, and a combination of fishery and tourism.
