国内首次！广东突破黄鳍金枪鱼人工配合饲料驯化

Core Viewpoint - Guangdong has achieved a significant breakthrough in the artificial domestication of yellowfin tuna using formulated feed, marking the first successful land-based cultivation of this species in China [4][7][62]. Group 1: Industry Context - Tuna is one of the most sought-after seafood products globally, and the exploration of artificial breeding has become a hot topic in the industry [2][3]. - The global tuna trade volume is projected to reach approximately 4 million tons in 2024, representing a year-on-year increase of 28%, with a total value of $15.67 billion, up 3.32% [54][55]. - The Asia-Pacific market is becoming increasingly active, with countries like South Korea, Thailand, and Malaysia purchasing between 30,000 to 40,000 tons annually [56]. Group 2: Technological Achievements - The Guangdong Agricultural Technology Promotion Center has successfully introduced a total of 263 yellowfin tuna, achieving a survival rate of 72% during domestication [5][6]. - The base has developed a specialized formulated feed primarily composed of eel powder, algae powder, vitamins, fish oil, yeast, and a small portion of miscellaneous fish, which has shown high acceptance by the tuna [18][19]. - The base has established a customized intelligent water circulation system to maintain optimal conditions for the high oxygen demand of yellowfin tuna [11][12]. Group 3: Future Prospects - The successful domestication of yellowfin tuna is expected to pave the way for artificial breeding experiments, which could significantly enhance the industry's sustainability and productivity [48][66]. - The Guangdong government aims to create a replicable "Guangdong Plan" for land-sea coordinated cultivation of tuna, contributing to the high-quality development of modern marine ranching [61][62]. - Future collaborations with research institutions are planned to expand tuna farming into deeper waters, enhancing the overall cultivation strategy [67].
