“海上粮仓”依托规模化、智能化拓展发展空间 海水养殖从内湾走向深远海

Core Viewpoint - The deep-sea aquaculture platforms in Fuzhou, Fujian, are experiencing a bountiful harvest, particularly of "wild-like" large yellow croaker, indicating a successful aquaculture model that mimics natural conditions [1][5]. Group 1: Aquaculture Environment - The deep-sea aquaculture platform in Dinghai Bay is stable and well-constructed, measuring over 60 meters in length and 32 meters in width, equivalent to five standard basketball courts [4]. - The aquaculture area spans 500 acres, featuring a combination of deep-sea villas and various deep-water net cages, creating a picturesque marine landscape [4]. - The environment is ideal for fish growth, with a water depth of 30 meters and a strong water exchange, providing a "wild-like" habitat for the fish [11]. Group 2: Fish Quality and Harvest - The large yellow croaker being harvested weighs over 2.5 pounds each, with a streamlined body and firm texture, attributed to their growth environment [8][16]. - The fish are raised in conditions that simulate the wild, with a survival rate exceeding 90% even under extreme weather conditions [13]. - Compared to nearshore aquaculture, the platform-raised fish are longer and thicker, with wholesale prices 4 to 5 times higher than those from nearshore farms [16]. Group 3: Technological and Scale Advancements - The aquaculture operation is characterized by high levels of scale and intelligence, with the platform capable of holding 1.58 million cubic meters of water and raising 200,000 large yellow croakers [19]. - Smart devices for water quality monitoring and video surveillance allow for real-time management of the aquaculture operations from shore [19]. - By 2025, the combined output of the two platforms is projected to reach 600 tons, generating nearly 100 million yuan in revenue [19]. Group 4: Regional Development and Strategy - Lianjiang County is recognized as a significant aquaculture region in China, actively promoting deep-sea aquaculture projects to transition from inshore to deep-sea farming [21]. - The local government has invested in 11 deep-sea aquaculture platforms as part of the "Hundred Platforms, Ten Thousand Tons" initiative, aiming for large-scale and intelligent development in marine food production [21].
