Core Insights - The article discusses the development of a modern marine ranch operated by China Communications Construction Company (CCCC) in Dandong, which aims to enhance marine resource utilization and ecological protection, aligning with national strategies for ocean development [1][2]. Group 1: Project Overview - The marine ranch project has a total planned investment of 5.2 billion yuan, focusing on marine resource development and ecological restoration [1]. - The project is located in a unique marine environment at latitude 39°, which is known for its low-temperature, clear waters, and strong self-purification capabilities, making it suitable for cultivating fish species [2]. Group 2: Fish Cultivation Techniques - The project has successfully implemented a "south fish, north breeding" strategy, selecting large yellow croaker and greenfin horse mackerel as trial species, achieving significant breakthroughs in fish farming [2]. - The farming density is controlled at approximately 3 kg per cubic meter, allowing fish to have more space to grow, resulting in firmer meat and a shape closer to wild fish [2]. Group 3: Technological Integration - The project incorporates a "deep sea + land" collaborative monitoring system to collect real-time data on water temperature and salinity, optimizing feeding and maintenance strategies [2]. - The large yellow croaker produced in this marine ranch is noted for its rich nutritional content and firm texture, showcasing the integration of ecological farming and smart technology [2]. Group 4: Government Support and Future Plans - The local government has provided comprehensive support for the project, facilitating its establishment and operation through dedicated services and planning [2]. - The first phase of the marine ranch plans to invest 589 million yuan, with the construction of 27 gravity-type net cages and 2 intelligent farming platforms, aiming to enhance fish habitats and contribute to marine ecological restoration [2][3]. Group 5: Financial Projections - The marine ranch is expected to generate an estimated revenue of 30 million yuan by the end of the year, reflecting the potential for growth in the marine economy [3].
