我国科研团队培育出“无肌间刺”银鲫

Core Insights - 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 intermuscular bones [1][2] - The new variety, referred to as "Zhongke No. 6," shows significant improvements in growth rate, survival rate in aquaculture, and feed utilization [1] - This innovation is part of a six-year project aimed at advancing agricultural breeding from traditional methods to a more predictable and programmable "precision design" era [1] Technology and Innovation - The research team utilized "molecular scissors" to edit the genetic code that controls the growth of intermuscular bones, significantly reducing their presence in the fish [1] - The breeding system also ensures that the new silver crucian carp is sterile, preventing it from reproducing in natural environments, thus addressing ecological safety concerns [1] Agricultural Impact - The advancements in breeding technology are expected to enhance food security and agricultural modernization in China, providing a more efficient way to produce high-quality protein with fewer resources [1][2] - The project is part of a broader initiative to create a strong "Chinese core" for national food security [2]
