Core Viewpoint - The article highlights the innovative "land-sea relay aquaculture" technique for salmon farming in Shandong, which successfully addresses the challenges of raising salmon in warm temperate marine environments [1] Group 1: Aquaculture Process - The land-sea relay aquaculture involves breeding high-quality salmon in freshwater before transferring them to seawater for further growth, marking a significant advancement in aquaculture technology [1] - A large-scale transfer of salmon is taking place at the central fishing port in Rizhao, Shandong, where salmon are being moved from land-based farms to large transport vessels for the fattening phase [3] - Prior to the transfer, salmon undergo health checks, including blood tests, to ensure they can adapt to the seawater environment after a 20-day acclimatization period on land [6] Group 2: Transportation and Survival Rates - The transport vessel is equipped with 12 fish tanks, each capable of holding 30,000 salmon, and maintains a continuous flow of seawater to enhance the survival rate during transportation [8] - The journey to the ocean is likened to a comfortable "marine high-speed train," ensuring the salmon arrive safely at their new habitat [8] Group 3: New Habitat and Production Capacity - The new marine habitat for the salmon, referred to as a "sea villa," is a large net cage measuring 89 meters long and 45 meters wide, with a water volume of approximately 60,000 cubic meters, capable of housing over 200,000 salmon [15] - The annual production capacity of this facility is projected to reach 1,000 tons of salmon, with plans to build four additional intelligent net cages, potentially increasing total annual production to 6,000 tons [17] - The factory-style, intensive, and smart aquaculture method reduces the average growth cycle of salmon by about 30%, making them more affordable and appealing to consumers compared to wild salmon [17]
