10余年攻坚“良种芯片” ，南沙“院士鱼”养成记

Core Viewpoint - The article highlights the successful breeding and cultivation of the hybrid fish species He Fang Yan, developed by a team led by Chinese Academy of Engineering academician Liu Shaojun, showcasing its economic and ecological benefits in aquaculture [1][2][6]. Group 1: Breeding and Cultivation Process - The He Fang Yan fish, known for its rapid growth and high meat yield, was created through a decade-long research effort involving hybridization techniques [2][3]. - The breeding process involves meticulous selection of parent fish based on physical attributes and vitality, followed by precise environmental control during fertilization and hatching [3][4]. - The breeding team conducts seasonal migrations to optimize breeding conditions, starting in Hainan and moving northward as temperatures rise [3]. Group 2: Economic Impact and Market Integration - A 7-acre fish pond can yield over 30 million yuan in total output, with the fish being sold at a market price of 10 yuan per pound [1][5]. - The integration of technology in aquaculture, including automated systems for monitoring and managing water quality, enhances operational efficiency and data-driven decision-making [4][5]. - The He Fang Yan fish demonstrates adaptability to brackish water environments, achieving high fertilization and hatching rates, which supports sustainable aquaculture practices [5][6]. Group 3: Strategic Alignment and Future Prospects - The breeding and cultivation of He Fang Yan align with China's "14th Five-Year Plan" to strengthen seed innovation and promote the revitalization of the seed industry [1][2]. - The successful cultivation of this fish species not only benefits local aquaculture but also contributes to the high-quality development of the Guangdong fishery industry [6].
