The 150,000-ton Guoxin-1 2-2 is an aquaculture vessel invested in and operated by Qingdao Guoxin Group. Its primary mission is to conduct year-round continuous onboard farming experiments for Atlantic salmon and other salmonid species. The vessel is equipped with 15 standard farming tanks, with a total aquaculture water capacity of approximately 100,000 cubic meters. Each tank holds more than 6,000 cubic meters of water — equivalent to roughly two to three standard swimming pools. Harvest (per tank?) is  3,000 high-quality salmon weighing 12 tons.

High-quality salmonids such as Atlantic salmon require extremely strict temperature and water-quality conditions. Guoxin-1 2-2 uses a mobile onboard tank farming system, allowing it to move north and south along China’s coast during cultivation. This mobility enables the vessel to proactively avoid natural disasters such as typhoons and red tides.

The aquaculture vessel is also equipped with China’s first deep-water intake system. By continuously pumping cold seawater at temperatures between 10°C and 16°C from depths of 30 to 50 meters, the system overcomes the challenge of maintaining suitable temperatures for salmon farming throughout the year.

In addition, the vessel’s smart feeding system can accurately deliver multiple types of feed around the clock in precise amounts and at precise times, revolutionizing traditional manual aquaculture methods.

Thousands of sensors are installed throughout the ship, providing 24-hour intelligent monitoring of water temperature, salinity, dissolved oxygen levels, and fish conditions, significantly reducing aquaculture risks.
