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].
