Atlantic salmon are known for their strict requirements for water temperature and quality. To address that challenge, the vessel is equipped with China's first deep-sea water intake system for aquaculture ships, continuously drawing cold seawater from depths of 30 to 50 meters where temperatures remain between 10 and 16 degrees Celsius.

The ship also uses an intelligent feeding system capable of delivering multiple types of feed around the clock with precise timing and quantities, replacing much of the labor-intensive work associated with traditional fish farming.

Thousands of onboard sensors monitor the water temperature, salinity, dissolved oxygen levels and fish activity around the clock, helping reduce farming risks and improve efficiency.

Industry observers say the "mobile farming" model could reshape the future of deep-sea aquaculture by overcoming geographical and seasonal limitations while offering consumers a more stable and quality-controlled source of domestically produced salmon.
