“无刺鲫鱼”有望端上餐桌

Core Viewpoint - The research team led by academician Gui Jianfang from the Chinese Academy of Sciences has developed a breeding technology system that creates a new candidate variety of silver crucian carp with high yield, disease resistance, and feed efficiency, while also eliminating the presence of small bones in the fish [1][2] Group 1: Breeding Technology and Innovations - The new breeding technology utilizes "molecular scissors" to edit the genetic code that controls the growth of small bones, significantly reducing their occurrence [1] - The candidate variety "Zhongke No. 6" shows substantial improvements in growth rate, survival rate in aquaculture, and feed utilization efficiency [1] - The breeding system is designed to produce sterile fish, preventing them from reproducing in natural environments, thus ensuring ecological safety [1] Group 2: Implications for Food Security and Agriculture - The innovations aim to enhance national food security and modernize agriculture, providing a strong foundation for China's agricultural development [2] - The advancements mark a shift in agricultural breeding from traditional methods to a more predictable and programmable "precision design" era [1]
