Core Viewpoint - The delivery of the "Suhai No. 1," the world's first self-propelled closed salmon farming vessel, marks a significant advancement in deep-sea salmon farming in China, with the potential to produce 8,000 tons of salmon annually, aiming to replace imports and lower prices for consumers [1][2]. Group 1: Vessel and Technology - "Suhai No. 1" is designed by the Chinese Academy of Fishery Sciences and built by China Shipbuilding Industry Corporation, featuring self-navigation capabilities and the ability to operate year-round by relocating to optimal water temperatures [2][3]. - The vessel can travel at speeds up to 18 km/h and has a range of 20,000 nautical miles, allowing it to evade adverse weather conditions, thus enhancing the safety and stability of salmon farming [3][4]. - The closed farming system simulates natural conditions, ensuring optimal growth environments for salmon, with 15 closed compartments that allow for intelligent management of water, oxygen, feed, light, and waste [3][4]. Group 2: Production and Market Impact - The first batch of salmon from "Suhai No. 1" is expected to be available for sale around the Dragon Boat Festival in 2024, with the potential for a stable and sufficient supply of salmon in the market [5]. - The vessel's design allows for multi-functional use, enabling the farming of various high-value fish species, which could further enhance the seafood supply chain in China [5]. - The integration of an automated salmon processing facility onboard allows for efficient processing, with a capacity of 100 tons for fresh processing and 5 tons for quick freezing, ensuring freshness and quality that can compete with imported products [4][5]. Group 3: Industry Transformation - The successful delivery of "Suhai No. 1" represents a shift in the fishing industry from nearshore capture to deep-sea intelligent manufacturing, setting a new industrial standard for future aquaculture projects [4][5]. - The innovative design and construction methods used in building "Suhai No. 1" have improved efficiency, reducing the construction cycle to 28 months and achieving a 35% increase in design efficiency and a 16% increase in construction efficiency [4].
