Core Viewpoint - Shandong is leveraging its marine resources to enhance food security and economic growth through the development of a "blue granary" concept, focusing on both land and sea food sources [2][4]. Group 1: Marine Economic Development - Shandong aims to achieve a total aquatic product output of 9.53 million tons and a fishery economic output value of 490.4 billion yuan by 2024 [2]. - The province is transitioning from traditional fishing and aquaculture to a more sustainable "marine ranching" model, which has increased per-acre yields by over 30% compared to conventional methods [3]. Group 2: Technological Advancements in Aquaculture - The launch of the world's first 150,000-ton smart fishery vessel, "Guoxin 1号2-1," represents a significant upgrade in marine ranching capabilities, designed to produce approximately 3,600 tons of high-quality fish annually [4]. - Shandong has established over 2,800 gravity-type deep-water cages and 37 large-scale deep-sea aquaculture facilities, expanding its aquaculture water volume to 4 million cubic meters [4]. Group 3: Breeding and Processing Innovations - The province leads the nation with 17 national-level aquatic breeding farms and has formed a breeding consortium involving 26 leading enterprises and 30 research teams [5]. - Shandong's processing industry is enhancing the value of marine products, with the oyster industry alone generating a total industrial chain value of 10 billion yuan through various processed products [5].

Core Viewpoint - Shandong is promoting a "big food" concept that emphasizes sourcing food from both land and sea, aiming to establish the ocean as a "blue granary" to ensure food security and enhance the fishing economy [2][6]. Group 1: Aquaculture Development - The province aims for a total aquatic product output of 9.53 million tons and a fishery economic output value of 490.4 billion yuan by 2024 [2]. - Shandong is transitioning from traditional fishing and aquaculture to a "fishing husbandry" model, utilizing multi-layered aquaculture systems that increase per-acre yields by over 30% compared to traditional methods [3]. Group 2: Deep-Sea Aquaculture - Shandong is advancing into deep-sea aquaculture, exemplified by the delivery of the world's first 150,000-ton smart fishery vessel, "Guoxin 1号2-1," which can produce approximately 3,600 tons of high-quality fish annually [4]. - The province has established over 2,800 gravity-type deep-water cages and 37 large deep-sea aquaculture equipment, with a total aquaculture water volume reaching 4 million cubic meters [4]. Group 3: Seed Industry and Innovation - Shandong leads the nation with 17 national-level aquatic seed breeding farms and has formed a breeding consortium with 26 leading enterprises and 30 research teams [5]. - The province has developed 65 new aquatic species, accounting for 21% of the national total, focusing on species like oysters, sea cucumbers, and shrimp [5]. Group 4: Value-Added Processing - The province is enhancing the value of its aquatic products through deep processing, transforming fresh products into high-value goods [5]. - The oyster industry in Lushan, with a cultivation area of 600,000 acres and an annual output of 500,000 tons, has a full industry chain worth 10 billion yuan, with 65% of fresh oysters going to processing plants [5].
