Core Viewpoint - The development of large-scale deep-sea aquaculture equipment is breaking the geographical barriers of fish farming and reshaping the national seafood landscape in China [1][3]. Group 1: Deep-Sea Aquaculture Equipment - The "Jinghai 002" deep-sea intelligent net cage measures 68 meters in length and width, and 40 meters in height, enclosing 94,000 cubic meters of water, allowing for the cultivation of salmon in suitable winter conditions [2]. - The intelligent monitoring, feeding, and harvesting systems enable a small team of three to four people to manage the equivalent of what would traditionally require 200 people on land [2]. Group 2: Innovative Aquaculture Practices - The company has successfully implemented a "land-sea relay" model for salmon farming, achieving a total production of 2,000 tons in 2023, with 1,500 tons from seawater and 500 tons from land-based recirculating aquaculture [1][3]. - Various fish species are being cultivated using innovative methods, such as the "relay" farming of species like the yellow croaker and southern sea bream, which optimizes growth cycles and reduces environmental pressure on coastal areas [3]. Group 3: Future Development Plans - The company aims to expand its aquaculture scale and contribute to national initiatives like the "Marine Granary" project, while also exploring marine breeding, island tourism, and recreational fishing to achieve integrated development across industries [3].

Core Viewpoint - Yantai's deep-sea aquaculture equipment is breaking barriers in fish farming, reshaping the national seafood landscape by enabling the cultivation of seafood in a manner similar to greenhouse vegetable farming [1] Group 1: Deep-Sea Aquaculture Innovations - The introduction of the "Jinghai 002" deep-sea intelligent net cage allows for the cultivation of salmon in suitable winter sea conditions, with the potential for fish weights to double by June or July next year, reaching over 4 kilograms [2] - Yantai Jinghai Marine Fisheries has successfully implemented a new "land-sea relay" model for salmon farming, achieving a total salmon production of 2,000 tons this year, including 1,500 tons from seawater and 500 tons from land-based recirculating aquaculture [2][4] - The "Jinghai 002" net cage measures 68 meters in length and width, and 40 meters in height, enclosing 94,000 cubic meters of water, thus overcoming spatial limitations for wintering salmon [2] Group 2: Operational Efficiency and Technology - The use of intelligent monitoring, feeding, and harvesting systems allows a small team of three to four people to manage the equivalent of what would traditionally require 200 people on land [3] - Eight such intelligent net cages have already been deployed by Yantai Jinghai Marine Fisheries, enhancing operational efficiency in deep-sea aquaculture [3] Group 3: Broader Aquaculture Strategies - The company is also innovating with other fish species, such as the breeding of "Yushi Pingyu" and "Zhen Diao," to shorten farming cycles and alleviate nearshore environmental pressures [4] - Seasonal and geographical barriers in aquaculture are being dismantled, with practices like "land-sea relay" and "fish species rotation" being implemented to meet market demands across different regions [4] - The Shandong Province's 14th Five-Year Plan emphasizes the acceleration of deep-sea development, aiming to integrate marine breeding, tourism, and recreational fishing into a cohesive development strategy [4]
